I am a Ph.D. student working with Professor Kannan Ramchandran in the Department of Electrical Engineering and Computer Sciences at University of California, Berkeley. I am part of both BASiCS lab and Wireless Foundations. I received my Master of Arts in Statistics and Master of Science in Electrical Engineering in May 2009, both from University of California, Berkeley. I did my undergraduate degree of Bachelor of Engineering in Electronic Engineering in Tsinghua University from 2002 to 2006. My current research interests include peer-to-peer systems, image/video signal processing, statistical learning and information theory.
