About Me

I am an Assistant Professor of Computer Science at Cornell University.

My research lies at the intersection of 3D computer vision and robotics. Specifically, I am interested in developing robust computational tools that allow us to model, reconstruct, and simulate the dynamic world from sparse, noisy, and unconstrained sensory data.

Prior to joining Cornell, I was a Young Investigator/Postdoc at AI2/University of Washington. I received my Ph.D. from MIT, where I worked with Antonio Torralba (aka the Great Torralba) and Raquel Urtasun. Previously, I was a Senior Research Scientist at Uber ATG R&D and Waabi working on self-driving vehicles. I completed my M.S. in Robotics at Carnegie Mellon University (CMU), where I was advised by Kris M. Kitani.

Prospective students: I am always looking for motivated and talented students! If you are interested in collaborating or joining my group as a PhD/MS/Undergrad student or intern, please read this.

Pro bono office hour

Inspired by Prof. Kyunghyun Cho and Krishna Murthy, starting January 2021, I have decided to commit 1~2 hours every week to provide guidance, suggestions, and/or mentorships for students from underrepresented groups or whoever is in need. Please fill in this form if you are interested.

Need more (diverse) opinions? Consider talking to people with different expertise or from different background: Tongzhou Wang (ML/RL), Alexander Haojan Liu (Speech/NLP), Zhijian Liu (ML), Vlas Zyrianov (CV), Yuan Shen (CV), Jun Gao (CV/Graphics).
