I'm a research scientist at Google Research, in Mountain View, where I work on machine learning, computer vision, and deep learning. Before Google, I was a postdoctoral fellow in SAIL in the Computer Science Department at Stanford University. Before Stanford, I finished my Ph.D in Computer Science at UC Berkeley in late 2014. My graduate study was fully supported by Samsung Lee Kun Hee Scholarship Foundation (Now Samsung Scholarship Foundation) for five years. In summer 2013, I spent a wonderful time at LEAR, INRIA as a visiting student researcher. My research interests are in machine learning, computer vision, and deep learning. Broadly, I'm interested in solving challenging problems in artificial intelligence. Also, I'm an invited reviewer for NIPS, ICML, SIGGRAPH, TPAMI, IJCV, RSS, ICCV, ECCV, CVPR, CVIU, and ICRA.
