Researcher

Fei Xia

Fei Xia is a robotics researcher whose work spans simulation for embodied agents and language-guided robot control. He earned a bachelor's degree at Tsinghua in 2016 and a Stanford electrical-engineering PhD in 2021, coauthored Gibson Env and iGibson, and announced plans to join Robotics at Google. His work includes SayCan, RT-1, PaLM-E, RT-2 and Open X-Embodiment; AdaFDR won the RECOMB Best Paper Award in 2019, and he coauthored a 2024 study of physically grounded vision-language models. As of October 2026, he is a Member of Technical Staff at Anthropic, after research roles at Meta and Google DeepMind.

Timeline

  1. 2016–2021

    Gibson Env and iGibson

    He earns a bachelor's degree at Tsinghua in 2016 and begins a PhD in electrical engineering at Stanford. In 2018, he coauthors Gibson Env, a simulation that virtualizes real spaces for embodied agents; in 2019, AdaFDR wins the RECOMB Best Paper Award, and iGibson 1.0 launches in December 2020 with 15 interactive home-sized scenes and 108 rooms. In March 2021, he announces plans to join Robotics at Google as a research scientist that fall, and in May 2021 he defends his thesis on large-scale simulation for embodied perception and robot learning.

  2. 2022

    SayCan and RT-1

    SayCan grounds language-model instructions in feasible robot skills, and he coauthors the 2022 RT-1 paper, a Robotics Transformer for real-world control.

  3. 2023

    PaLM-E, RT-2 and Open X

    He coauthors PaLM-E, which incorporates visual and continuous sensor inputs into a language model. RT-2 combines a pretrained vision-language model with robot data for action, while Open X-Embodiment pools data from 22 robot types.

  4. 2024

    Physically grounded vision-language models

    He coauthors the ICRA 2024 paper “Physically Grounded Vision-Language Models for Robotic Manipulation,” which introduces PhysObjects, an object-centric dataset of 39.6K crowd-sourced and 417K automated physical-concept annotations of household objects.

  5. As of October 2026

    Member of Technical Staff

    He is a Member of Technical Staff at Anthropic after working as an AI Research Scientist at Meta and a Senior Staff Research Scientist and Tech Lead Manager on Google DeepMind's Robotics team.
