NVIDIA Research org chart — with rosters

1 · TL;DR

2 · Explore the org

Click any row to open its roster. Search filters people across every group at once; the tier chips switch evidence levels on and off.

3 · What this pass corrected

4 · How reliable each number is

• Tier A (309) — on an official roster, or the person's own page names the group. Treat as fact.
• Tier B/C (40/42) — strong or weak inference from bios and affiliations.
• Tier D/E (20/6) — reconstructed from co-authorship alone. All of RVP and much of Cosmos and ADLR sit here.
• The 400+ figure traces to one TechCrunch article (12 Aug 2025). NVIDIA's own about page still says "more than 200 scientists" and is stale. The 448 profiles are not a headcount — Sanja Fidler, Bryan Catanzaro and Mark Ren have no profile at all, while departed people remain listed.
• 46 duplicate placements were removed where a person appeared in both a parent org and one of its groups; the group placement wins.

5 · Per-group caveats

Learning and Perception Research (LPR) — lead Jan Kautz · page

• RVP vs SRL: RESOLVED IN FAVOR OF LPR. The LPR landing page explicitly enumerates 'Robotic Visual Perception Research (RVP)' as one of the five named LPR teams. Stan Birchfield does NOT appear in the Seattle Robotics Lab 'Members' widget (SRL is led by Yashraj Narang as Team Leader) - he only shows up in SRL's publication author index because he co-authors heavily with SRL people. His own site says he leads a small CV+robotics group but never names it. So: RVP is under LPR; the SRL author-index hit is a false positive. Residual ambiguity: RVP is the only LPR team with no page/link at all, and Birchfield is Seattle-based and co-publishes constantly with SRL, so functionally the boundary is blurry.
• Zhiding Yu's group has NO public roster. The only tier-A fact is his own bio ('research lead at the LPR Group'). Everything about who is IN the group is inference from the Eagle / Eagle 2 / Eagle 2.5 / LocateAnything / FB-BEV / Hydra-MDP author lists. Highest-confidence members: Zhiqi Li and Jindong Jiang. Wonmin Byeon and De-An Huang are plausible but unproven.
• A large fraction of the recurring Eagle co-authors are NOT LPR: Andrew Tao and Bryan Catanzaro (ADLR VPs), Guilin Liu (Principal RS & Team Leader, multimodal LLM - reads as a peer ADLR team lead), and the Nemotron-VL applied cluster (Karan Sapra, Nadine Chang, Subhashree Radhakrishnan, Amala Sanjay Deshmukh, Tuomas Rintamaki, Matthieu Le, Ilia Karmanov, Lukas Voegtle, Philipp Fischer, Timo Roman, Max Ehrlich, Tyler Poon). None of these have research.nvidia.com/person pages. I deliberately did NOT list them as LPR members.
• Shiyi Lan (11 co-authorships with Zhiding Yu, incl. Hydra-MDP and FB-OCC) is a Senior Research Scientist on the NVIDIA AV Applied Research team, not LPR.
• SEVERAL research.nvidia.com/person/<slug> pages EXIST but return HTTP 403 'Access denied - You are not authorized to access this page' (unpublished nodes): de-an-huang, guilin-liu, hongxu-danny-yin, shiyi-lan, orazio-gallo, xin-dong, shizhe-diao. I set nvidia_page to '' for those rather than emit a broken link.
• The cached persons.json has a broken 'name' field (every entry is the literal string 'People'); the slug is the only usable identifier. Its 'labs' field is also very sparse - only 7 people are tagged 'LPR' even though LPR is one of the largest orgs.

NVIDIA Spatial Intelligence Lab (formerly the NVIDIA Toronto AI Lab) — lead Sanja Fidler · page

• RENAME CONFIRMED: https://research.nvidia.com/labs/toronto-ai/ now serves a JS redirect to https://research.nvidia.com/labs/sil/. The SIL homepage states: 'We have joined forces with the Dynamic Vision and Learning Group, the High-Fidelity Physics Research Group, the Applied Autonomous Vehicle Research Group, and were previously named the Toronto AI Lab.'
• KEY QUESTION - ARE DVL AND PRL INSIDE FIDLER'S ORG? YES, and there is a direct primary statement, not just a LinkedIn post. The Toronto AI Lab / SIL homepage read (archived 2025-06-11 and 2025-08-13 at web.archive.org/web/20250813112504/https://research.nvidia.com/labs/toronto-ai/): 'As of April 2024, we have proudly joined forces with Ken Museth and his physics research team. Since December 2024, we also welcome the addition of Laura Leal-Taixe's team to our lab.' The current SIL site repeats the merge in the present tense. Stronger still: the SIL Members page (people.js) lists ALL PRL and DVL people in one single roster with Sanja Fidler pinned at the top - they are not shown as a separate collaborating lab.
• The SIL roster (members/people.js) has 83 entries. This file lists the 54 that are NOT in the PRL block or DVL block; those 15 + 12 are in prl.json and dvl.json respectively. Total across the three files = 83 minus overlaps, plus 2 SIL-only interns broken out.
• A THIRD team was absorbed that the brief did not mention: the Applied Autonomous Vehicle Research Group (AVAR) led by Jose M. Alvarez. It is named on the SIL homepage and confirmed independently by Rafid Mahmood's homepage. Its people (Alvarez, Maying Shen, Nadine Chang, Shiyi Lan, Alex/Xinglong Sun, Rafid Mahmood) overlap with the separate NVIDIA lab page /labs/av-applied-research/ - coordinate with whoever covers that lab to avoid double-counting.
• CONTRADICTION: Haithem Turki is on the SIL members roster, but his own homepage says he is in the AI-Mediated Reality and Interaction (AMRI) group. He also has an NVIDIA /person/ page. Flagged as ambiguous.
• STALE/DEPARTED CANDIDATES: Seung Wook Kim's listed homepage now redirects to a KAIST lab page; Michal Tyszkiewicz's homepage still describes him as an EPFL PhD candidate; Jenny Schmalfuss's university page only documents NVIDIA internships. Several people on the Aug-2025 Toronto AI Lab roster (Huan Ling, James Lucas, Jonah Philion, Tobias Pfaff, Jianfei Guo) are absent from the current SIL roster and appear to have left.

NVIDIA Cosmos Lab (formerly Deep Imagination Research, DIR) — lead Ming-Yu Liu · page

• The lab publishes no roster. research.nvidia.com/labs/cosmos-lab/ has no Members widget (neither does the archived /labs/dir/ page from 2023 or 2025), so no member here is tier A by the 'lab page members widget' rule. Every tier-A claim below rests on the person's own homepage or their research.nvidia.com bio.
• The org was renamed: /labs/dir/ (Deep Imagination Research) now 301-redirects to /labs/cosmos-lab/. Both names are still used in the wild - some homepages say 'NVIDIA Cosmos Lab', others still say 'NVIDIA Deep Imagination Research'. The site-wide nav on research.nvidia.com still says 'Deep Imagination' and links to /labs/dir/, i.e. the nav is stale.
• FINLAND / HELSINKI GROUP VERDICT: Tero Karras, Miika Aittala, Samuli Laine, Timo Aila, Jaakko Lehtinen and Janne Hellsten are NOT in this org. Evidence: (a) none of them appears on the Cosmos Lab or Deep Imagination pages; (b) they are absent from every Cosmos technical report author list (Predict1/Transfer1/Reason1/Predict2.5/Transfer2.5/Cosmos 3); (c) of 67 publications on the official Cosmos Lab publication list they appear on only 3 (FUNIT 2019, eDiff-I 2022, llm-for-image-gen 2025) and always as collaborators, never as the senior author; (d) their own lineage (StyleGAN2/3, EDM, EDM2, autoguidance) never includes Ming-Yu Liu; (e) their NVIDIA bios are graphics-rooted (Karras: 'pivotal role in the development of NVIDIA's RTX technology'; Laine: 'photorealistic and real-time rendering, voxel-based graphics, GPU ray tracing'; Aila: 'real-time rendering ... hardware architectures'), and persons.json tags Laine and Aila with 'RTR'. They sit in the graphics-research line (Timo Aila's Helsinki group, historically under David Luebke's graphics research, adjacent to the Real-Time Graphics lab), not under Ming-Yu Liu.
• CAVEAT on the Finland group: they do not appear on the current Real-Time Graphics (rtr) Members widget either, so 'Real-Time Graphics' is an inference from their bios and history rather than a verified roster entry. The only safe statement is: not Cosmos Lab, and graphics-research lineage.
• CONFIRMED DEPARTURES (former Cosmos Lab / Deep Imagination, do not count as current members): Shitao Tang (now Rhoda AI; his site says 'founding member of Cosmos World Foundation Model and core contributor to Cosmos 1, 2 and 3'), Fangyin Wei (now Tesla AI; 'previously senior research scientist at NVIDIA CosmosLab'), Haoxiang Wang (now Luma AI; 'core contributor to NVIDIA Cosmos'), Yunhao Ge (previously RS at NVIDIA Deep Imagination Research), Yu Zeng (now Toyota Research Institute), Xian Liu (now xAI). Older Deep Imagination alumni visible in the lab publication list: Arun Mallya (9 pubs) and Xun Huang (8 pubs), neither of whom has a current NVIDIA person page.
• CROSS-LAB COLLABORATORS who appear in Cosmos reports but belong to other orgs, so they are excluded from members: Sanja Fidler + Spatial Intelligence Lab / ex-Toronto AI (Huan Ling, Xuanchi Ren, Tianchang Shen, Jiahui Huang, Kevin Xie, Seung Wook Kim, Tianshi Cao); Jan Kautz + LPR (Sifei Liu - her homepage explicitly says 'I work with the LPR team led by Jan Kautz'; Zhiding Yu; Shiyi Lan; Hanzi Mao is ambiguous); Marco Pavone + AV lab (Boris Ivanovic, Xinshuo Weng, Wenhao Ding, Yulong Cao, Boyi Li, Yan Wang, Wenjie Luo, Ed Schmerling - all on the avg Members widget); Dieter Fox + Seattle Robotics Lab (Kaichun Mo - bio says 'Research Scientist at Seattle Robotics Lab', Yashraj Narang, Alperen Degirmenci, Hugo Hadfield, Xuning Yang, Wei Yang, Anqi Li, Fabio Ramos); GEAR (Jim Fan, Yuke Zhu, Joel Jang, Scott Reed, Shuran Song); ADLR/Nemotron (Wei Ping, Boxin Wang, Mohammad Shoeybi, Mostofa Patwary, Deepak Narayanan, Bryan Catanzaro); Efficient AI (Song Han, Han Cai); Healthcare/MONAI (Daguang Xu, Dong Yang, Yufan He, Nic Ma).

NVIDIA Applied Deep Learning Research — lead Bryan Catanzaro · page

• Q1 ANSWER: Bryan Catanzaro's title is confirmed current as 'Vice President, Applied Deep Learning Research' at NVIDIA (NVIDIA's own developer-blog author page, and an April 2026 HumanX speaker bio that adds 'leading the Nemotron team building open foundation models'). He still leads ADLR. No source found suggesting a successor or a change.
• Q2 ANSWER: Nemotron is BOTH. (a) It is the model/dataset family that ADLR produces - ADLR's own project index hosts Nemotron-CC, Nemotron-MIND, Nemotron-CrossThink, Nemotron-CORTEXA, Nemotron-H and NVIDIA Nemotron Nano 2. (b) Since ~Dec 2025 it also has its own lab microsite (research.nvidia.com/labs/nemotron/) that appears as a separate entry named 'Nemotron' in NVIDIA's Research Labs listing, carrying the Nemotron 3 Nano/Super/Ultra, Nemotron-Cascade, LatentMoE and QAD posts. The direct source tying them together is Catanzaro's HumanX 2026 bio: 'VP of Applied Deep Learning Research at NVIDIA, leading the Nemotron team building open foundation models' - i.e. the same person leads both, and the Nemotron site is best read as a productized spin-out surface of ADLR's foundation-model line rather than an independent lab. Note the personnel shift: the Nemotron-site posts (LatentMoE, RL speculative decoding) are authored largely by a hardware/architecture co-design group (Bita Rouhani, Ritika Borkar, Venmugil Elango, Ran Zilberstein, Tiyasa Mitra), not by the classic ADLR names, so the Nemotron 3 effort is broader than ADLR.
• Q3 / persons.json: persons.json is UNUSABLE for name matching - every one of the 448 records has name == 'People' (the scraper grabbed the page header, not the person name). I matched on slugs instead. Of ~66 roster names, only THREE have a research.nvidia.com/person/ page at all: Siddharth Gururani, Ali Hatamizadeh and Chao-Han Huck Yang - and the latter two are arguably LPR/NV-Research rather than ADLR. Bryan Catanzaro, Mohammad Shoeybi, Mostofa Patwary, Wei Ping, Andrew Tao, Rafael Valle and Jared Casper all return HTTP 404 on research.nvidia.com/person/<slug>. None of them appears in people.html either.
• Q4 ANSWER (visibility): ADLR's own landing page says its work 'is less connected to publication cycles' and that 'some of our best and most impactful work could never be published due to lack of academic novelty'. The consequence is structural: the ADLR lab site has NO members widget, no /people, /team or /author pages (all 403/404), and no publication list rendered (research.nvidia.com/labs/adlr/publications/ is an empty page). The same is true of the Nemotron site. There is no roster anywhere on research.nvidia.com. Estimate: the Nemotron-H project page alone credits ~197 distinct named contributors, of whom only 8 have a research.nvidia.com person page - and all 8 belong to OTHER labs (LPR, DLER, Efficient AI). So roughly 95-98% of the people doing ADLR/Nemotron work never appear on research.nvidia.com at all. The only reliable public surface for ADLR affiliation is developer.nvidia.com/blog/author/<handle> bios and personal homepages; that is where every tier-A datum in this file comes from.
• STALE/CONTRADICTORY: Rafael Valle's NVIDIA developer-blog bio still describes him as a current 'senior research scientist at NVIDIA', but his own site says he has since gone to Meta Superintelligence Labs and is now Chief Science Officer at Rime. Treat the NVIDIA bio as stale. Similarly Raul Puri (Megatron-era ADLR) is now at OpenAI per his NVIDIA blog bio.
• CHIP DESIGN CAVEAT: ChipNeMo is NOT primarily an ADLR paper. Its lead authors (Mingjie Liu, Nathaniel Pinckney, Haoxing Ren, Brucek Khailany) sit in the EDA / 'ASIC & VLSI Research' group - persons.json tags Mingjie Liu with labs=['EDA'] and Khailany's bio says he 'leads the ASIC & VLSI Research group'. Mingjie Liu's current NVIDIA blog bio in fact places him on the Learning and Perception Research team now. ADLR's chip-design people are Rajarshi Roy, Jialin Song, Jonathan Raiman, Robert Kirby and Teodor-Dumitru Ene (PrefixRL, CircuitVAE, Nemotron-CORTEXA), with Catanzaro as a ChipNeMo co-author bridging the two groups.

Efficient AI — lead Song Han · page

• Roster read directly from https://research.nvidia.com/labs/eai/people/ on 2026-07-29: Members > Principal Investigators: Song Han; Researchers: the other eight.
• EAI is NOT Pavlo Molchanov's group. Pavlo leads DLER, a separate LPR team. The two co-author heavily (VILA/NVILA/OmniVinci), which is the usual source of confusion.
• Yao (Jason) Lu: no homepage emitted - sites.google.com/site/yaolubrain returned 200 but contained zero occurrences of his name, so it was dropped rather than guessed.
• Only Song Han and Han Cai have research.nvidia.com/person pages; the other seven do not.
• Song Han's bio also names an 'NVIDIA Singapore Lab' that he co-leads - an org not present in the research-labs listing. Unresolved whether it is a research org or a site.

NVIDIA Autonomous Vehicle Research Group — lead Marco Pavone · page

• Roster taken verbatim from the 'Meet the Team' widget on https://research.nvidia.com/labs/avg/ : Members 23, Faculty Scientists 3, Current Interns 17, Alumni 33 (alumni not included in members).
• NO sub-team leads are published for the four research thrusts (Next-Gen AV Architectures, AV Foundation Models, Simulation, AI Safety for AVs). The thrust->person mappings in 'subgroups' are tier-E inference from bios/publications, NOT stated by NVIDIA.
• Boris Ivanovic is the only member whose NVIDIA bio carries a management title ('Senior Research Scientist and Manager'). No one in AVG is described as Principal/Distinguished/Director except Pavone himself.
• STALE PAGE: Wenhao Ding's AVG author page still says 'Research Intern ... concurrently pursuing a Ph.D. at CMU', but his research.nvidia.com/person page says 'research scientist in the autonomous vehicle research group'. Treated as Research Scientist.
• STALE PAGE: Xinshuo Weng's AVG author page still describes her as a CMU PhD student / research intern; her /person page title is 'research scientist'. Treated as Research Scientist.
• Yurong You has NO research.nvidia.com/person/ page (404) despite being a full member with a Research Scientist bio; his lab page is https://research.nvidia.com/labs/avg/author/yurong-you/ .

NVIDIA Seattle Robotics Lab — lead Yashraj Narang · page

• LEADERSHIP RESOLVED. Dieter Fox is no longer at NVIDIA. He founded the Seattle lab in 2017 and was NVIDIA's Senior Director of Robotics Research; GeekWire reported on 2025-07-10 that he left NVIDIA for the Allen Institute for AI (Ai2) to lead a new robotics initiative, and that his NVIDIA position 'has been taken over by NVIDIA Robotics Research Manager Yash Narang'. His own UW homepage now says 'I am now sharing my time between UW and Ai2' with no current NVIDIA role, and Crunchbase/LinkedIn list him as Senior Research Director at Ai2. So it is not a 'Fox kept a larger robotics org while handing SRL to Narang' arrangement — he left the company outright and Narang took over.
• Corroborating negative evidence: Dieter Fox does not appear anywhere in the 448-person research.nvidia.com people directory crawl, and https://research.nvidia.com/person/dieter-fox now returns HTTP 403 while every other person URL tested returns 200 or a clean 404 — consistent with the page being pulled. He is also absent from the SRL 'Members' widget.
• STALE ARTIFACT: the SRL site still has a legacy author page https://research.nvidia.com/labs/srl/authors/dieter-fox/ that lists him as 'Director / NVIDIA / University of Washington'. That page is an auto-generated publication-author stub, not a roster entry, and its title is out of date.
• Fox is still a co-author on 2026 SRL papers (DexMachina, GraspGen, PEEK, Robometer). These are external/academic collaborations (UW + Ai2) or work in the pipeline from before he left, not evidence of an NVIDIA role.
• ORG RELATIONSHIP: SRL, GEAR and DAIR are three distinct groups. SRL is its own top-level NVIDIA Research lab (it is the entry listed as 'Robotics' at research.nvidia.com/labs, url /labs/srl). GEAR (Generalist Embodied Agent Research, led by Jim Fan and Yuke Zhu) and DAIR (Data-Driven AI for Robotics, led by Umar Iqbal) are BOTH teams inside the Learning and Perception Research (LPR) organization led by Jan Kautz — the LPR page names its teams as GEAR, Data-Driven AI for Robotics, RVP, DLER and GenAIR, and the DAIR page says 'We are part of the Learning and Perception Research (LPR) organization'. SRL is not under LPR. Overlap is topical (all three do robot foundation models / manipulation / humanoids) and collaborative (e.g. SRL and GEAR both contribute to Isaac Lab-Arena), not organizational.
• ROSTER CORRECTION vs the brief: the Members widget currently has 19 entries, not 17+1. The brief's name list omitted Yixuan Wang. Full widget = Yashraj Narang (Team Leader) + Alexander Lefort (Lab Technician) + 17 researchers; plus Tucker Hermans under a separate 'Faculty Scientists' heading (counted in members here, giving 20). Interns 2026 has 13 people, not 11.

NVIDIA Real-Time Graphics Research (formerly Real-Time Rendering Research; internally NVR-RTG) — lead Aaron Lefohn · page

• NAME OF THE LAB HAS CHANGED: the site title and Lefohn's current bio say 'Real-Time Graphics Research' (and Saeed Hadadan's bio uses the internal abbreviation NVR-RTG). Many members' bios still say 'real-time rendering research group' - stale text, same team. The old Drupal person page for Lefohn also still says 'Real-Time Rendering Research team'.
• FINLAND GENERATIVE-MODELS QUESTION (answered from the graphics side): Tero Karras, Miika Aittala, Samuli Laine, Timo Aila and Jaakko Lehtinen are NOT members of RTR. Evidence: (1) none of the five appears in the RTR lab page's own Members or Interns widget (tier-A negative); (2) none appears in the RTR publication-author roster in lab_rosters.json (50 slugs, all accounted for as members, interns, or external academic co-authors); (3) they DO have research.nvidia.com/labs/rtr/author/<slug>/ pages, but those pages are auto-generated stubs with NO bio and NO 'NVIDIA' role line, and list only legacy co-authored papers (Noise2Noise 2018, Interactive Reconstruction/Recurrent Denoising Autoencoder 2017, Appearance-Driven Automatic 3D Model Simplification 2021, MesoGAN, Texture LOD for Real-Time Ray Tracing) - that is tier-E co-authorship evidence only.
• FINLAND QUESTION, cause of the false positive: persons.json shows labs:['RTR'] for samuli-laine and timo-aila. That field was derived from the 'Research Area(s)' block on their Drupal person pages, which lists the TOPIC tag 'Real-Time Rendering' (alongside 'Generative AI', 'Computer Vision', 'High Performance Computing', etc.). It is a subject tag, not a team. Tero Karras, Miika Aittala and Jaakko Lehtinen have labs:[] entirely. Do not read RTR membership out of that field.
• FINLAND QUESTION, where they actually sit: the generative side. research.nvidia.com/labs/dir (Deep Imagination Research) now issues a permanent redirect to research.nvidia.com/labs/cosmos-lab - i.e. Deep Imagination has been rebranded/absorbed into the Cosmos Lab, and Ming-Yu Liu's person page still reads 'Vice President of Research at NVIDIA... leads the Deep Imagination Research group... focuses on deep generative models'. Karras's own bio says 'Senior Distinguished Research Scientist... current research interests revolve around deep learning, generative models, and digital content creation... primary author of the StyleGAN family'; Aila's says 'currently working on machine learning, with a special focus on generative models such as StyleGAN'; Laine's says 'Currently Dr. Laine focuses on deep learning'. CAVEAT: the current Cosmos Lab landing page publishes no members widget at all, so I could NOT positively confirm their listing on a Cosmos/Deep-Imagination roster - my claim is a strong tier-A negative for RTR plus a tier-B/C positive inference for the Deep Imagination / Cosmos generative org. Jaakko Lehtinen is additionally a professor at Aalto University and has historically been a part-time NVIDIA researcher.
• Miika Aittala appears once on the GenAIR (Fundamental Generative AI Research, Arash Vahdat) lab page - as a co-author on 'Align Your Flow' (NeurIPS 2025) with Karsten Kreis / Arash Vahdat / Morteza Mardani, not in the GenAIR Members widget. Another data point that his collaboration network is the generative-AI org, not RTR.
• SUB-TEAM STRUCTURE IS LARGELY UNPUBLISHED. The RTR lab page names exactly one role: Lefohn as 'Team Leader'. No other member carries a role label. The only sub-team lead I could evidence is Chris Wyman (Research Director, Redmond WA, 'leading a small group') and that comes from his own homepage, not from NVIDIA. Everything else in the 'subgroups' array below the Redmond entry is a geographic or thematic clustering I inferred - treat accordingly.

AI-Mediated Reality and Interaction Research Group — lead Shalini De Mello · page

• STRUCTURAL FINDING - AMRI is NOT part of LPR. Confirmed four independent ways: (1) AMRI's own lab page never names a parent org, unlike DAIR's page which explicitly says 'We are part of the Learning and Perception Research (LPR) organization within NVIDIA Research'; the archived AMRI page of 2025-03-25 instead said AMRI sits 'within the larger NVIDIA Research orgnization [sic]'. (2) LPR's own lab page enumerates its constituent teams - GEAR, Data-Driven AI for Robotics (DAIR), RVP, DLER, GenAIR - and AMRI is absent from that list. (3) research.nvidia.com/labs lists 'AI-Mediated Reality and Interaction' as a top-level lab, peer to 'Learning and Perception'. (4) Shalini De Mello's bio uses the past tense for LPR.
• EXACT SELF-DESCRIPTION (from $SCRATCH/persons/shalini-de-mello.html, current): "Shalini De Mello is a Director of Research, New Experiences, leading NVIDIA's AI-Mediated Reality and Interaction (AMRI) Research group. Previously, she was a Distinguished Research Scientist in the Learning and Perception Research group at NVIDIA."
• DATING THE SPLIT (Wayback captures of research.nvidia.com/person/shalini-de-mello): 2022-09-25 = 'Principal Research Scientist and Research Lead in the Learning and Perception Research group'; 2023-09-28 = 'Distinguished Research Scientist in the Learning and Perception Research group'; 2024-04-15 through 2025-10-07 = 'Director of Research, New Experiences and a Distinguished Research Scientist at NVIDIA, where she leads the AI-Mediated Reality and Interaction Research Group. Previously, she was a researcher in the Learning and Perception Research Group at NVIDIA, FROM 2013 TO 2023.'; from 2026-01-14 onward the dual title is dropped and only 'Director of Research, New Experiences' remains. So: she left LPR at the end of 2023, AMRI was stood up as its own group in late 2023/early 2024 (the AMRI lab site's first Wayback capture is 2024-04-14), and the residual 'Distinguished Research Scientist' half of her title was retired between Oct 2025 and Jan 2026.
• WHAT IS 'NEW EXPERIENCES' - it is a RESEARCH org inside NVIDIA Research, not a product-side org. It predates AMRI: Ben Boudaoud's NVIDIA bio says he 'joined NVIDIA in January 2018 as research staff in the New Experiences Research group' and Joohwan Kim's says he 'is a vision scientist in Nvidia's New Experience research group'. Both are now listed on the HPX (Human Performance and Experience) lab page, i.e. HPX is the renamed/continuing core of New Experiences Research. External profiles of David Luebke (VP of Graphics Research, NVIDIA Research) describe him as running a group of ~35 researchers focused on 'New Experiences'. Luebke reports to Bill Dally (Chief Scientist / SVP of Research). Corroborating: David Luebke is a recurring senior co-author on AMRI papers (Play4D, QUEEN, AI 3D Selfie, Avatar Fingerprinting, Real-time 3D Visualization of Radiance Fields), which he was not on the older LPR-era AMRI work. CAVEAT: NVIDIA has never published an org chart, so 'New Experiences reports to Luebke' is tier-B inference from person bios plus third-party profiles, not a first-party statement.
• AMBIGUITY: 'New Experiences' is also used by AMRI as the name of one of its four 2024-era research thrusts ('New Experiences: enabled by AI (3D video conferencing, content creation, XR, LLMs)'), which makes the org name and the thrust name easy to confuse on the archived pages.
• LPR AUTHOR INDEX: NO current AMRI member appears on the LPR author index. I paged the full index (research.nvidia.com/labs/lpr/authors/, 19 pages, 186 author slugs) and none of the 10 AMRI members is present - including Shalini De Mello herself. NUANCE: legacy per-author term pages still resolve (HTTP 200) for /labs/lpr/author/shalini-de-mello/, /koki-nagano/ and /michael-stengel/, but they list only pre-2025 LPR-era papers (SimAvatar, CosAE, Avatar Fingerprinting, Dream-in-4D, GAvatar, RegionGPT, etc.) and are orphaned from the index. So the LPR site retains AMRI members' historical publications but no longer counts them as LPR people.

Human Performance and Experience Research Group — lead Joohwan Kim · page

• CORRECTION to the task brief: 'hpx' is NOT High-Fidelity Physics. research.nvidia.com/research-labs maps 'High-Fidelity Physics' -> /labs/prl/ (page title 'NVIDIA High Fidelity Simulation Research') and 'Human Performance and Experience' -> /labs/hpx/. So HPX does not duplicate PRL; they are different labs.
• /labs/hpe/ does not exist (S3 403). There is no 'hpe' lab.
• The lab page shows no titles or role labels for members, only research-area badges and Google Scholar links.

Perception, Action and Reasoning Research (NVIDIA Research Israel / Tel-Aviv Lab) — lead Gal Chechik · page

• PAR expands to 'Perception, Action and Reasoning' per research.nvidia.com/research-labs; the lab site brands itself 'NVIDIA Tel-Aviv Lab' / 'NVIDIA Research Israel AI Lab'. Same org.
• Shai Cohen (research.nvidia.com/person/shai-cohen) is tagged PAR in the cached persons.json but does NOT appear in the lab page Members widget - excluded, flagged.
• Yuval Atzmon's yuvalatzmon.github.io returns 200 but shows only 'Under construction...' - dropped rather than cited.
• The 'labs' tag field inside the cached persons.json is unreliable (e.g. it tags pure circuits researchers as 'EDA'); only lab-page Members widgets were trusted as tier A.

NVIDIA Research Taiwan (Taiwan Research Lab), founded 2022 — lead Yu-Chiang Frank Wang · page

• The TWN page also lists 19 Alumni (Sheng-Yu Huang, Ci-Siang Lin, Chien-Yi Wang, Yun Da Tsai, Shih-Yang Liu, Hsu-kuang Chiu, Mu-Yi Shen, Shun-Cheng Wu, Yen-Ting Lin, Kris Wu, Chunghyun Park, Kai-Po Chang, Miran Heo, Yoonwoo Jeong, Zhen Wan, Xiaoqian Shen, Huck Yang, '(Design Automation Research) Wen-Hao Liu', Joe Yang). Several of these (Huck Yang, Chien-Yi Wang, Yun Da Tsai, Shih-Yang Liu, Wen-Hao Liu) still have active NVIDIA person pages - 'Alumni' here appears to mean 'left the Taiwan lab', not 'left NVIDIA'.
• A naive scrape of the Members widget returns 40 names because Members + Current interns + Alumni share one widget; correct split is 12/9/19.
• labs/twn.html was NOT in the pre-fetched cache; I fetched it fresh.

NVIDIA Design Automation Research Group (Electronic Design Automation Research) — lead Haoxing (Mark) Ren · page

• The lab landing page's nav links to '#people' but the fetched HTML contains NO people widget - the members section appears broken/removed. The roster above was reconstructed from /labs/electronic-design-automation/index.json, which contains exactly 11 individual author profile pages (plus the group profile); every one lists affiliation 'NVIDIA'. Mingjie Liu added separately as tier D.
• The lab's /authors/ index (4 pages, ~34 names) is a publication-author index and includes external academics - Sung Kyu Lim (Georgia Tech), Zhiru Zhang & Niansong Zhang (Cornell), Cunxi Yu, Yibo Lin & Runsheng Wang (Peking), Mark Po-Hung Lin, Pruek Vanna-Iampikul, Kishor Kunal, Anthony Agnesina, Johannes Maximilian Kuehn etc. Those are NOT members.
• Distinct from the NVIDIA Circuits Research group (Tom Gray) and ASIC & VLSI Research group (Brucek Khailany), even though the cached persons.json mis-tags several circuits researchers (Brian Zimmer, Brent Keeth, Matt Fojtik, John Wilson, Stephen Tell, Walker Turner, Xi Chen, Trey Greer, Angad Rekhi, Ben Lee, Li Xu, Youssef Elasser) as 'EDA'.
• research.nvidia.com/person/haoxing-mark-ren and /person/mark-haoxing-ren both 403 for automated fetches; both are indexed by search engines. Slug included but unverified.

NVIDIA Conversational AI (NeMo) Research — lead Boris Ginsburg · page

• The conv-ai site is an MkDocs site with only Home / Research Notes / Publications. It publishes NO member roster and NO named lead. Site self-description: 'The Conversational AI NeMo team works on ASR, Speaker Diarization, Text To Speech, Speech Enhancement and Speech Translation research. Our work is the foundation for NVIDIA Riva.'
• Content is stale: the Research Notes and Publications archives stop at 2024.
• Lead attribution to Boris Ginsburg is tier C - it comes from third-party profile aggregators (Crunchbase/RocketReach/Wiza list him as 'Senior Director, Conversational AI' at NVIDIA) and from his authorship on NVIDIA NeMo technical blog posts. He has NO research.nvidia.com/person page. Do not treat as confirmed.
• Because there is no roster, no members are listed rather than guessing from publication author lists.

Digital Biology Labs / Digital Biology Research — lead · page

• The DBR site is a JavaScript content hub (papers / blogs / demos backed by content.json, 19 items). It has NO people page, NO member roster and NO named lead anywhere in the HTML or the JSON. I could not establish a lead from any primary source - left empty rather than guessed.
• Of the 177 distinct authors in the site's content.json, only 6 have research.nvidia.com/person pages: Kieran Didi (8 items), Arash Vahdat (5), Tomas Geffner (3), Zuobai Zhang (3), Karsten Kreis (3), Xi Chen (2). Most frequent authors overall (Christian Dallago 10, Martin Steinegger 6, Milot Mirdita 4, Zhonglin Cao 4, Emine Kucukbenli 4, Alejandro Chacon 4, Micha Livne 3, Danny Reidenbach 3) are NVIDIA product/engineering staff or external collaborators (EMBL-EBI, Seoul National Univ., Univ. Mainz) - tier E only.
• The overlap with GenAIR (Vahdat, Kreis, Geffner, Zhang) suggests digital-biology *research* is largely done inside the Fundamental Generative AI Research group rather than by a separate research lab; DBR looks like a cross-org publishing surface. Flagged as inference, not verified.

Applied Research in Autonomous Vehicles (AV Applied Research) — lead Jose M. Alvarez · page

• YES, it is a separate lab from AVG. research.nvidia.com/research-labs lists 'Autonomous Vehicles' (/labs/avg/, Marco Pavone, Director of Autonomous Vehicle Research) and 'Applied Research in Autonomous Vehicles' (/labs/av-applied-research/, Jose M. Alvarez) as two entries. Alvarez's team is described as maximizing the impact of research advances on the AV product; Pavone's is the fundamental AV research lab.
• No member of this lab has a research.nvidia.com/person/ page - the whole roster is only on the lab's own site (which is hand-written HTML, not the standard Wowchemy template).
• Alumni listed on the page (former team members): Jonhathan Howe, Jiwoong Choi, Yashar Asgarieh, Barath Lask... (list truncated in fetched HTML).

Data-Driven AI for Robotics (DAIR) — lead Umar Iqbal · page

• Roster is complete and exactly matches the 12 names given for verification plus the lead. The DAIR Members widget lists exactly 13 people; no missing members and no extras were found.
• https://research.nvidia.com/labs/dair/ returns 403 to a plain curl but 200 with a browser User-Agent. The cached $SCRATCH/labs/dair.html in the shared brief was a 403 error page (303 bytes) - it has been replaced with the real page.
• Xue Bin (Jason) Peng: he holds a genuine dual appointment - NVIDIA Research Scientist AND Assistant Professor at Simon Fraser University. He is listed in DAIR's main Members widget as a regular member, not segregated into a 'Faculty Scientists' section the way NVIDIA's Seattle Robotics Lab does for Tucker Hermans. Verdict: NVIDIA staff with a concurrent faculty position, NOT an external academic collaborator. Kevin Xie is a similar case (NVIDIA Research Scientist while a UofT/Vector PhD student).
• NAME COLLISION: research.nvidia.com/person/haotian-zhang is a DIFFERENT Haotian Zhang - 'Senior Research Scientist at NV Cosmos', PhD from University of Washington, GLIP CVPR 2022 Best Paper Finalist. The DAIR Haotian Zhang did his PhD at Stanford under Kayvon Fatahalian and works on human motion. The DAIR member has NO /person/ page; nvidia_page deliberately left empty.
• SITE BUG: the DAIR author page for Jiefeng Li (https://research.nvidia.com/labs/dair/author/jiefeng-li/) serves Karsten Kreis's social/homepage links in its icon bar (karstenkreis.github.io, twitter.com/karsten_kreis, Kreis's Scholar ID). Jiefeng Li's real homepage https://jeffli.site/ was recovered by search and verified 200.
• STALE PAGE: Umar Iqbal's /person/ bio still reads 'Senior Research Scientist ... part of the Machine Learning and Perception group headed by Jan Kautz'. His DAIR page (newer) correctly says 'Sr. Research Manager ... leading DAIR'. The DAIR title is used.

Deep Learning Efficiency Research (DLER), NVIDIA Research — lead Pavlo Molchanov · page

• ANSWER TO THE CORE QUESTION: DLER and EAI are TWO DISTINCT GROUPS, not one group under two names. DLER = Deep Learning Efficiency Research, led by Pavlo Molchanov, founded 2023, sits under Jan Kautz's LPR (research.nvidia.com/labs/lpr explicitly lists 'Deep Learning Efficiency Research (DLER)' as one of LPR's teams alongside GEAR, DAIR, RVP and GenAIR). EAI = Efficient AI, research.nvidia.com/labs/eai, led by Song Han (Distinguished Scientist / research director at NVIDIA, associate professor at MIT). Their published rosters are DISJOINT: EAI's own people page lists Song Han (PI) plus Yao (Jason) Lu, Enze Xie, Han Cai, Ligeng Zhu, Zhijian Liu, Yukang Chen, Yujun Lin, Yuyang Zhao — none of whom appear on the DLER team page, and none of the DLER members appear on EAI's. The two teams DO co-author heavily (VILA, NVILA, VILA-HD, OmniVinci all carry both Molchanov/Yin and Song Han/Yao Lu), which is almost certainly the source of the confusion.
• HONGXU (DANNY) YIN: he is NOT a co-lead of DLER and does NOT lead a separate team. The DLER team page lists him under plain 'Members'; only Molchanov carries the 'Team Lead' label. His actual title, from his own site, is 'Principal Research Scientist & Research Lead at NVIDIA' — i.e. research lead of the multimodal/VILA thrust within DLER. LPR's team list contains no Yin-led team.
• PAVLO MOLCHANOV'S TITLE: he is a Research Director / Director of Research, NOT a Distinguished Research Scientist. Sources: his own site ('I'm a Research Director at NVIDIA leading DLER team'; bio: 'he is now a Research Director leading a deep learning efficiency team') and his LinkedIn headline ('Director of Research at NVIDIA'). He is a manager. CONTRADICTION: his official research.nvidia.com/person/pavlo-molchanov bio is stale and still reads 'currently holding a senior research scientist position' — that text predates the 2023 founding of DLER.
• STALENESS WARNING: nv-dler.github.io is the only official DLER roster and it is stale — footer says '© 2024' and the newest news item is May 2025. It therefore misses at least one confirmed current member (Hanrong Ye) and still lists two people who have LEFT NVIDIA (below).
• DEPARTED MEMBERS (were on the DLER team page, no longer at NVIDIA — deliberately excluded from the members list): (1) Xin Dong, formerly on-device/efficient LLMs and project lead of the DLER RL paper — his site simonxin.com now says he 'leads a research team on LLMs training at Seed @ ByteDance' and 'previously worked at NVIDIA'. (2) Shizhe Diao, formerly Senior Research Scientist (data quality/efficiency, CLIMB) — shizhediao.github.io now says 'I am a member of technical staff at Thinking Machines Lab. Previously, I was a senior research scientist at NVIDIA Research.' Both of their research.nvidia.com person pages now return 'Access denied' (unpublished), consistent with departure.
• research.nvidia.com/labs/dler returns 403 Forbidden (both the cached copy and a fresh fetch with a browser UA), including labs/dler.authors.html — so there is no NVIDIA-hosted DLER members widget or author index to cross-check against. The GitHub Pages site nv-dler.github.io is the only working official roster.

NVIDIA Dynamic Vision and Learning Group — lead Laura Leal-Taixé · page

• MERGE CLAIM CONFIRMED (December 2024), primary source, not LinkedIn: the NVIDIA Toronto AI Lab / SIL homepage stated 'As of April 2024, we have proudly joined forces with Ken Museth and his physics research team. Since December 2024, we also welcome the addition of Laura Leal-Taixe's team to our lab.' Archived at http://web.archive.org/web/20250813112504/https://research.nvidia.com/labs/toronto-ai/ (also present in the 2025-06-11 snapshot; ABSENT from the 2024-11-27 snapshot, which mentions only the Museth merge - so the DVL line appeared between Nov 2024 and Jun 2025, consistent with a December 2024 date).
• SECOND INDEPENDENT CONFIRMATION: every DVL member appears in the single SIL Members roster at https://research.nvidia.com/labs/sil/members/ (members/people.js), and the current SIL homepage says 'We have joined forces with the Dynamic Vision and Learning Group ... and were previously named the Toronto AI Lab'. Shengyu Huang's homepage independently says 'Nvidia Dynamic Vision and Learning Group, part of Nvidia Spatial Intelligence Lab'. So DVL is INSIDE Fidler's org, not a peer lab.
• The December 2024 date is the date the TEAM merged into Fidler's lab. It is NOT the date Laura Leal-Taixé joined NVIDIA - she left her TUM tenure-track post in 2022 and was already running DVL at NVIDIA well before then (DVL publications under NVIDIA affiliation predate Dec 2024). Do not conflate the two.
• The cached lab_members.json parse of 'dvl' had 20 people with names broken (all rendered as '">'). Verified against the raw HTML: the 20 slugs and roles are correct. I split them 12 members / 8 research interns using the roles printed in NVIDIA's own Members widget.
• The three PhD students (Sven Elflein, Alessandro Burzio, Benjamin Missaoui) are listed by NVIDIA under 'Members' on the DVL page but are tagged status:intern in the SIL people.js. I kept them as members and flagged the conflict per-person. Cristiano Saltori has the same conflict but his own NVIDIA bio explicitly says Research Scientist, so he is a member without qualification.
• 'Half of the group is currently still located at the Technical University of Munich' - DVL lab page. The group is Europe-based (Munich/Zurich), unlike SIL's Toronto core.

Generalist Embodied Agent Research — lead Linxi "Jim" Fan and Yuke Zhu (co-leads) · page

• ORG QUESTION RESOLVED, tier A: GEAR is INSIDE LPR, not a peer org reporting to Bill Dally. research.nvidia.com/labs/lpr states in body text: "Welcome to the homepage of NVIDIA's Learning and Perception Research (LPR) group, led by Dr. Jan Kautz. ... LPR consists of multiple teams: Generalist Embodied Agent Research (GEAR), Data-Driven AI for Robotics, Robotic Visual Perception Research (RVP), Deep Learning Efficiency Research (DLER), Fundamental Generative AI Research (GenAIR)." This is a declarative sentence, not a related-labs sidebar.
• Corroboration for the LPR parent: (a) the sibling DAIR page says "We are part of the Learning and Perception Research (LPR) organization within NVIDIA Research"; (b) the GenAIR page says the same; (c) GEAR people (Johan Bjorck, Jing Wang, Yinzhen Xu, Qi Wang, Spencer Huang, Yizhou Zhao, Valts Blukis) all have research.nvidia.com/labs/lpr/author/<slug>/ pages, i.e. GEAR publications are indexed under LPR; (d) Jan Kautz is a named co-author on GR00T N1/N1.5/N1.6, DreamGen, FLARE, NitroGen and is one of three joint advisors (with Fan and Zhu) on Vesta - a pattern consistent with him being the org lead above GEAR, not an outside collaborator. LPR in turn sits under NVIDIA Research (Bill Dally), so Dally is the grandparent, not the direct parent.
• Countervailing signal worth naming: Jim Fan's and Yuke Zhu's public titles are both "Director", which some coverage reads as an independent org. No source was found placing GEAR outside LPR. Treat the LPR parent as established and the "Director" titles as level, not reporting line.
• GEAR publishes NO member roster: research.nvidia.com/labs/gear/ has only Home / Publications / Blog; /labs/gear/team/ and /labs/gear/people/ 404. The /labs/gear/publications/ page is a Next.js SSG route whose data payload is literally {"publicationsData":{}} - i.e. the publications list is empty/broken as of this crawl. This roster was reconstructed from the per-project pages instead (/gr00t-n1_5, /gr00t-n1_6, /dreamgen, /flare, /vesta, /egoscale), which do carry full author blocks.
• The single strongest roster proxy is the GR00T N1.6 page, whose byline reads "Authors (alphabetical): *GEAR Team, Allison Azzolini, Johan Bjorck, ..." - 58 named individuals badged collectively as the GEAR Team. But that list demonstrably over-collects: it includes Jan Kautz (LPR head), Zhiding Yu (LPR research lead), Ajay Mandlekar and Valts Blukis (Seattle Robotics Lab), and Yunhao Ge. Do not treat N1.6 authorship alone as GEAR membership.
• Jim Fan's title could NOT be verified on any nvidia.com surface. research.nvidia.com/person/linxi-jim-fan still says "Senior AI Research Scientist" and jimfan.me still says "Senior Research Scientist / Lead of AI Agents" - both stale. "Director of AI & Distinguished Scientist" comes from his LinkedIn headline; his X profile says "Director of Robotics & Distinguished Scientist". The two self-reported titles disagree with each other and with NVIDIA's own pages. Reported, not confirmed.

Fundamental Generative AI Research (GenAIR) Group — lead Arash Vahdat · page

• Roster is complete and exactly matches the 8 names given for verification plus the lead. No missing members were found: the GenAIR Members widget lists exactly 9 people (Arash Vahdat as Team Lead + 8).
• GenAIR explicitly states on its own page that it is part of the Learning and Perception Research (LPR) organization, and the LPR page reciprocally lists GenAIR as one of its five teams (GEAR, DAIR, RVP, DLER, GenAIR).
• Zuobai Zhang appears in BOTH the Members widget and the 'Current and Past Interns' list (Mila, 2024-2025). He converted from intern to full-time Research Scientist after his 2026 PhD; counted once as a member.
• Chao Liu: no bio and no personal homepage on either the GenAIR author page or his /person/ page. His /person/ publication list skews toward 3D portrait/avatar work (with Xueting Li, Shalini De Mello, Koki Nagano) while his GenAIR publications are video generation. NVIDIA itself links the GenAIR author entry to /person/chao-liu, so they are treated as the same person, but 'Chao Liu' is a common name at NVIDIA - flagging as a possible identity conflation.
• Morteza Mardani's /person/ page and his GenAIR author page both link to http://web.stanford.edu/~morteza/ which now 404s. Replaced with his current live homepage https://mortezamardani.github.io/morteza/ (verified 200) found via search.
• The four 'subgroups' listed are research themes on the GenAIR landing page, not formally named subteams with declared leads. Only Arash Vahdat carries an explicit leadership title on the site.

NVIDIA High-Fidelity Physics Research Group — lead Ken Museth · page

• HPX IS NOT THIS LAB. The brief's premise is wrong. https://research.nvidia.com/labs/hpx/ is the 'Human Performance and Experience Research Group' - esports, applied perception, HCI, display technology (Ben Boudaoud, Joohwan Kim, Josef Spjut, Ekta Prashnani, Ruth Rosenholtz, Peter Xenopoulos, Alex Zook, Jaehyun Jung). The NVIDIA lab index confirms two distinct rows: 'High-Fidelity Physics' -> /labs/prl/ and 'Human Performance and Experience' -> /labs/hpx/. HPX does NOT report to Sanja Fidler; it sits with the graphics/perception side of NVIDIA Research. There is zero personnel overlap with PRL.
• APRIL 2024 CLAIM CONFIRMED, primary source: the PRL lab page's own News section reads 'April 2024 - We are excited to join forces with Sanja Fidler and her AI research team' and links to research.nvidia.com/labs/toronto-ai/. The reciprocal statement is on Fidler's side too: the Toronto AI Lab homepage read 'Since April 2024, we are happy to join forces with Ken Museth and his physics research team' (archived 2024-11-27, web.archive.org/web/20241127014754/https://research.nvidia.com/labs/toronto-ai/), later reworded to 'As of April 2024, we have proudly joined forces with Ken Museth and his physics research team'.
• KEY QUESTION - INSIDE FIDLER'S ORG OR PEER LAB? INSIDE. Beyond the two reciprocal merge statements, every PRL member is listed in the single SIL Members roster at https://research.nvidia.com/labs/sil/members/ (members/people.js) with Sanja Fidler pinned first, and the SIL homepage lists the High-Fidelity Physics Research Group among the teams it 'joined forces with'. The SIL 'Physics Simulation' research area is this team. It is a subgroup, not a collaborator.
• COUNT CORRECTION: the cached lab_members.json had 15 members for prl. The live page has 16 - it is missing David I.W. Levin. Visiting Faculty (Denis Zorin, 1) and Interns (4) match. I list 17 in 'members' because I folded Denis Zorin in with an explicit Visiting Faculty flag; strict headcount is 16 members + 1 visiting faculty + 4 interns.
• AMBIGUOUS AFFILIATIONS: Eftychios Sifakis (Professor, UW-Madison) and David I.W. Levin (Associate Professor, U. Toronto) are both on the Members list; Levin's own bio confirms a Principal Research Scientist role at NVIDIA, Sifakis's does not mention NVIDIA at all. Denis Zorin is explicitly Visiting Faculty. Matthew Cong's bio says he works 'on the Omniverse team' while the members widget places him in High-Fidelity Physics.
• Francis Williams straddles PRL and the SIL core: he is on the PRL members widget and is the fVDB point of contact on two SIL pages, but he is absent from the current SIL people.js roster. Counted once, here.

Robotic Visual Perception Research (RVP) — lead Stan Birchfield

• PARENT ORG RESOLVED: RVP sits under LPR, NOT under SRL (Seattle Robotics Lab). Direct evidence: https://research.nvidia.com/labs/lpr/ states 'LPR consists of multiple teams' and lists exactly five - GEAR, Data-Driven AI for Robotics, Robotic Visual Perception Research (RVP), DLER, and GenAIR. Counter-evidence checked: the SRL Members widget (Yashraj Narang, Team Leader) does NOT contain Birchfield, Tremblay, Tyree, Blukis or Bowen Wen; SRL's only faculty scientist is Tucker Hermans.
• RVP HAS NO WEBSITE AT ALL. This is not a 403/UA problem. On the LPR page, GEAR, DAIR, DLER and GenAIR are hyperlinks; 'Robotic Visual Perception Research (RVP)' is the ONE entry rendered as plain text with no href. Every URL variant returns 403/404 with a browser UA: /labs/rvp/, /labs/rvp/index.xml, /labs/rvp/sitemap.xml, /labs/rvp/author/stan-birchfield/, /labs/rvp/publication/, /labs/robotic-visual-perception/, nv-rvp.github.io, nvidia-rvp.github.io. The Wayback Machine has ZERO snapshots of research.nvidia.com/labs/rvp/ (archived_snapshots: {}). url is therefore an honest empty string.
• CONSEQUENCE: there is NO tier-A evidence available for any RVP member. No lab Members widget exists, no /person/ bio anywhere in the 448-person cache mentions 'RVP' or 'Robotic Visual Perception' (grepped, zero hits), and the personal homepages of Bowen Wen, Stephen Tyree and Stan Birchfield were fetched and none names a sub-group. The member list below is RECONSTRUCTED and every entry is tier D or E.
• RECONSTRUCTION METHOD: co-authorship frequency with Birchfield as senior/last author, computed from his /person/ publication list (60 papers) and cross-checked against the 2025-2026 list on sbirchfield.github.io. Ranked NVIDIA co-authors: Jonathan Tremblay 33, Stephen Tyree 14, Bowen Wen 11, Valts Blukis 6, Charles Loop 6. Each candidate was then filtered on (a) having a research.nvidia.com/person/ page (= NVIDIA staff, not intern), and (b) a bio consistent with robotic visual perception.
• DELIBERATELY EXCLUDED, with reasons: Charles Loop (6 shared papers, but his bio places him in graphics/geometric modeling - Loop Subdivision, GPU font rendering - not robot perception); Wei Yang, Yu-Wei Chao, Fabio Ramos, Clemens Eppner, Adithyavairavan Murali, Balakumar Sundaralingam, Xuning Yang, Hugo Hadfield, Ankit Goyal, Yashraj Narang, Dieter Fox (all confirmed Seattle Robotics Lab members or SRL-side robotics, co-authoring GraspGen / cuRobo / RoboLab with Birchfield across org lines); Jan Kautz (LPR org head, senior author by role); Alex Zook (recurring co-author on 3D-Generalist, GRS, VoLo, RoboLab but his /person/ page has no bio and his work sits in simulation/games - ambiguous, flagged not assigned); Greg Heinrich (LPR efficiency/RADIO team); Jiefeng Li and Ye Yuan (confirmed DAIR members, appear on CARI4D).
• Bowen Wen title conflict: his /person/ bio says 'Senior Research Scientist', his own site says 'Staff Research Scientist'. Used the self-reported (newer) title.

6 · Candidate direct reports to Bill Dally

Everyone in the 448 profiles carrying a VP, director, distinguished or fellow title, with the org they appear to lead. Dieter Fox is excluded — he left in 2025. Reporting lines are inferred; NVIDIA publishes none.

7 · Still unresolved

• Who leads NVIDIA robotics research after Dieter Fox's 2025 departure to Ai2. The SRL lab page still lists Fox as an author; no successor is named anywhere public.
• Steve Keckler vs David Nellans: both /person bios claim to lead the Architecture Research Group. Cannot determine which is current from public sources.
• David Luebke vs Aaron Lefohn: both are described as 'VP of graphics research'. The actual split of the graphics org is not published.
• research.nvidia.com/person/{sanja-fidler, dieter-fox, haoxing-mark-ren, mark-haoxing-ren} all return HTTP 403 to both curl (browser UA) and WebFetch, while /person/william-dally returns 200. Search engines have these URLs indexed. Cannot tell whether the pages were removed or are selectively blocked.
• Digital Biology (DBR) has no published lead or roster.
• Conversational AI (conv-ai) has no published lead or roster; the site's content stops in 2024.
• Whether Arash Vahdat (GenAIR), Song Han (EAI), Shalini De Mello (AMRI), Jose M. Alvarez (AV Applied), Jean Kossaifi (AI for Scientific Simulation), Joohwan Kim (HPX), Haoxing Ren (EDA), Tom Gray (Circuits) and Brucek Khailany (ASIC & VLSI) report to Dally directly or through a VP. NVIDIA publishes no org chart; every 'direct report' claim above is an inference from 'X leads group Y inside NVIDIA Research'.
• Rama Akkiraju is 'vice president of AI for IT' and appears in the research people directory, but AI-for-IT is an NVIDIA IT function, not NVIDIA Research - deliberately excluded from direct_reports.
• Joel Emer's directory title reads 'director of microarchitecture' - this is a mis-scrape of his bio sentence about his former Intel role ('Director of Microarchitecture Research' at Intel). He is a Senior Distinguished Research Scientist / MIT Professor of the Practice in ARG, not a director at NVIDIA.
• org_count_estimate = 29 is: the 21 labs listed on research.nvidia.com/research-labs, plus 8 named research groups that have no /labs/ page (Architecture Research, Circuits Research, ASIC & VLSI Research, Programming Systems and Applications, Security & Privacy, Quantum Chemistry/Computing, Wireless/6G research, AI for Scientific Simulation). NVIDIA's own research-labs page says research spans '26 disciplines'. Treat 29 as +/- 5.
• Where the Helsinki generative-models group (Karras, Aittala, Laine, Aila, Lehtinen) sits. Two agents independently ruled out Cosmos Lab; they are also absent from the Real-Time Graphics member widget. Verified claim: not Cosmos.
• Zhiding Yu's multimodal group has no public roster. Only he is tier A; the rest is reconstructed from the Eagle and FB-BEV author lists.
• Jim Fan's title conflicts across three sources — LinkedIn says Director of AI & Distinguished Scientist, X says Director of Robotics, NVIDIA's page and his own site still say Senior Research Scientist.
