I successfully defended my PhD dissertation and graduated in Fall 2012. I will be joining Intel Labs, Santa Clara as a Research Scientist.

My PhD advisor is Dr.Chandra Kambhamettu. My research interests include topics in scene understanding, camera systems, stereo and 3D imaging, facial image analysis. My research is aimed towards enabling machines to answer questions such as, What objects do I see in this scene? Is this an object I can sit on? Where can I keep things on this object? Where am I? Is this the same person? Are these two people related? I also work on camera systems that can help find accurate 3D models, structures and distances in a given scene.
