I am a postdoctoral associate in Computer Science Department, Boston
University. As a member of Image and Video Computing (IVC) group,
I work with Prof. Margrit Betke and Prof. Stan Sclaroff .
My primary research interests focus on computer vision, machine learning and combinatorial algorithms. In particular, I have been working on object segmentation, detection and tracking. I got my Ph.d. degree in Computer Science from Boston University in 2012.
