I was born in Shanghai, a beautiful and fast-developing city in China. I am currently a Research Scientist in Facebook AI Research (FAIR). Before joining Facebook, I was a Researcher/Software Engineer in Google X, Self-driving Car team in 2013-2014. I am a recipient of ICCV 2013 Marr Prize Honorable Mentions for a hierarchical framework that gives globally optimal guarantees for non-convex non-rigid image deformation, and received Microsoft Research PhD Fellowship (2011-2013).
