I’m currently a research scientist & PI at Shanghai AI Laboratory. I am leading a research team containg over 20 talented researchers at Shanghai AI Lab, aiming at innovating to the transportation system in a data-driven way.

Previously, I worked as Deputy Director of R&D at Sensetime Technology Ltd, leading a product team containing over 30 talented engineers and product specialists, developing the RoboX Autonomous Products, including RoboBus & RoboSweeper.

I obtained my Ph.D. from The Chinese University of Hong Kong in May, 2020 supervised by Prof. Xiaogang Wang and Prof. Xiaoou Tang. I got my bachelor’s degrees of Electronic Engineering and Economics in Tsinghua University in 2016. I worked as an research intern at Microsoft Research Asia (MSRA) and Facebook Reality Labs (Now Meta Reality Labs) during my Ph.D. years.

Research interest: 3D Scene Reconstruction, 3D Scene Perception, Behavior & Scene Simulation, any Autonomous-Driving-related topic.

***Important*** Our team is searching for highly self-motivated interns / full-time employees / post-docs . If you are interested in solving the industrial problem in an academic way, do not hesitate to contact me.
