I am a fourth-year PhD student at Columbia University, advised by Shuran Song. I'm also a member of the Columbia Artificial Intelligence and Robotics (CAIR) lab. I'm broadly interested in robotics and computer vision.

Before coming to Columbia, I received my B.Eng. in Computer Science from Shanghai Jiao Tong University. During my undergrad, I was fortunate to work with Jiajun Wu and Josh Tenenbaum.
