I am an applied scientist working with Dr. Mu Li and Dr. Alex Smola in Amazon AI. Before joining Amazon, I received my PhD under the supervision of Shawn Newsam. My research interests mainly focus on large-scale video classification, semantic segmentation, optical flow/disparity estimation, surveillance anomaly detection, geo-event discovery etc.
