About me

I am currently a Research Scientist at Snap Research, working on computer vision and deep learning related projects. I have finished my Ph.D. in Computer Science at UCLA, advised by Professor Alan Yuille. Before joining UCLA, I obtained my M.E. (by research) degree in 2012 from Nanyang Technological University, Singapore, advised by Professor Junsong Yuan. I graduated from Huazhong University of Science and Technology with a B.E. degree in 2010.

I am fortunate enough to have worked closely with Dr. Zhengyou Zhang from Microsoft Research Redmond from 2011 to 2012, with Prof. Raquel Urtasun and Prof. Sanja Fidler at Toyota Technological Institute Chicago in 2013 Summer, with Dr. Hailin Jin, Dr. Zhe Lin, and Dr. Chen Fang at Adobe Research in 2015 Summer, and with Dr. Xiaoyu Wang, Dr. Ning Zhang and Dr. Jia Li at Snapchat Research in 2016 Spring.
