I am a PhD candidate at the ECE department. I work at the Center for Automation Research with Prof. Rama Chellappa. My research focus has been in statistics and geometry, applied towards problems in computer vision. During my graduate studies I have worked on a range of problems: acoustic-video fusion, multi-camera tracking, particle filtering, projective geometry, markerless motion capture, compressive sensing and performance evaluation. A summary of my research and projects I have worked on can be found here. Here is a link to some group lunch pictures
