I am a researcher with Microsoft Research since 1999, currently with the Multimedia, Interaction and Collaboration group. I received the B.S. and M.S. from University of Brasília (Brazil), and the Ph.D. from Georgia Tech, all in Electrical Engineering.
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 was an elected member of two IEEE SPS Technical Committees: Information Forensics and Security and Multimedia Signal Processing (for which I was also chair for 2014-15), and a member of the IEEE SPS Technical Directions Committee. I acted as general co-chair of MMSP’09, Hot3D’10, WIFS’11, and Hot3dD’13, and as Technical co-chair of WIFS’10, ICME’11, and MMSP’13. I am a fellow of the IEEE.
