I am a PhD student in the Department of Computer Science at UT Austin, advised by Dr. Kristen Grauman. I am broadly interested in Computer Vision and its applications to robotics.

Before coming to UT, I was an intern at MALL Lab, IISc, working with Dr. Partha Talukdar. I completed my B.E. in Computer Science from BITS Goa.
