Other

Before joining Microsoft, I was a member of the research staff at the David Sarnoff Research Center from 1996 to 1999. I was also a co-op student with AT&T Human Interface Lab (now part of NCR) from 1994 to 1996, and a Summer intern at Interval Research in 1994. I have published 100+ refereed papers, and authored 50+ granted patents. I am an elected member of two IEEE SPS Technical Committees: Information Forensics and Security and Multimedia Signal Processing (for which I’m also chair for 2014-15). I am an associate editor of the IEEE Transactions on Information Forensics and Security, and acted as general co-chair of MMSP’09, Hot3D’10, and WIFS’11, and technical chair of WIFS’10, ICME’11, and MMSP’13.
