About me

I'm a Senior Research Scientist at Google DeepMind where I work on the Robotics team. I received my PhD degree from the Department of Electrical Engineering, Stanford University. I was co-advised by Silvio Savarese in SVL and Leo Guibas. I was supported by Stanford Graduate Fellowship and Qualcomm Innovation Fellowship. During my PhD, I have done research internships with Dieter Fox at Nvidia, Alexander Toshev and Brian Ichter at Google. I obtained my bachelor's degree from Tsinghua University in 2016. [formal bio in EN/CN]

Research Interest

My mission is to build intelligent embodied agents that can interact with complex and unstructured real-world environments, with applications to home robotics. I have been approaching 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. Most recently, I have been exploring using foundation models for robot decision making.
