About me
I'm a Research Scientist with Google Research 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, and Alexander Toshev and Brian Ichter at Google. I obtained my bachelor's degree from Tsinghua University in 2016. 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 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.
Outreach
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.
