I am a startup founder in artificial intelligence, with a variety of research and product experiences on autonomous driving, videos, cameras, maps, advertisements, etc. My research aims at building lifelong autonomous agents. Previously, I worked at Google DeepMind, Baidu Apollo, Facebook AI Research, CMU Robotics, Apple, Google Streetview, and Comcast Labs DC. I received my Ph.D. in computer science from the University of Maryland College Park. My PhD thesis is spatial perception from visual and linguisitc information.
