I am a fifth-year PhD candidate at the Department of Electrical Engineering, Stanford University. I am co-advised by Silvio Savarese
and Leo Guibas
. I am supported by Stanford Graduate Fellowship
and Qualcomm Innovation Fellowship
. During my PhD, I have done research internships with Dieter Fox
at Nvidia, and Alexander Toshev
and Brian Ichter
at Google. I obtained my bachelor's degree from Tsinghua University in 2016.
My mission is to build intelligent embodied agents that can interact with complex and unstructured real-world environments, with applications to home robotics. I approach this problem from 3 aspects: 1) Large scale and transferrable simulation for Robotics. 2) Learning algorithms for long-horizon tasks. 3) Combining geometric and semantic representation for environments.
On weekends, depending on availability, I voluntarily host office hours for students (especially underrepresented groups and junior students) who want to get into the field of and develop a career on Machine Learning, Computer Vision, and Robotics. Each slot is 20-minute long. If you want to get advice from me, please fill out this questionnaire.
2021.5 I defended my PhD Thesis titled "Large Scale Simulation for Embodied Perception and Robot Learning".
2021.3 I will join Robotics at Google as a Research Scientist in the Fall.
2021.3 ReLMoGen accepted to ICRA2021.
2020.12 The wait is over! iGibson v1.0 was released! It comes with many new features and fully interactive environments, checkout the website for more details.
2020.4 iGibson was released! It is a large scale interactive environment for robot learning.
2020.3 I am co-hosting CVPR Challenge "Sim2Real Challenge with Gibson". It is the first Sim2Real challenge in CVPR.
2019.7 AdaFDR was accepted to Nature Communications.
2019.5 Will Shen and I won Qualcomm Innovation Fellowship as a team. Thank you Qualcomm!
2019.5 AdaFDR won best paper award at RECOMB2019.
2018.4 We will host a demo for Gibson Env at CVPR'18. Come and check it out!
2018.2 One paper accepted to CVPR'18 (spotlight).
