Biography [My CV]

I am a staff scientist in JD Digits, Mountain View, CA. Before that, I was a computer vision scientist in GE Global Research, Niskayuna, NY. From August 2015 to October 2016, I was a post-doc researcher in University at Albany, SUNY, US, worked with Prof. Siwei Lyu. I completed my Ph.D. in National Laboratory of Pattern Recognition in the Institute of Automation, Chinese Academic of Sciences at June, 2015. My Ph.D. supervisor is Prof. Stan Z. Li. Before that, I received the B. Eng degree from Automation Engineering Department in University of Electronic Science and Technology of China in 2010.

My research interest includes machine learning and computer vision, with a focus on object detection and tracking, video segmentation and pose estimation.
