I am a Research Software Design Engineer at the Communication, Collaboration and Signal Processing Group at Microsoft Research.  My current project is the Whiteboard Capture System and audio processing for Real-Time Communication.

I am on leave from the Ph.D. program at Stanford Graphics Laboratory.  where I worked on the design of a 3D scanning gantry and a real-time 3D video camera based on active light projection and other  computer graphics related projects.
