About me

I am an Associate Professor in the Manning College of Information and Computer Sciences at the University of Massachusetts, Amherst and the co-director of the Computer Vision Lab. I am also affilated with the Center of Data Science. Prior to this I was a Research Assistant Professor at TTI Chicago, a philanthropically endowed academic computer science institute in the University of Chicago campus. I obtained my PhD under the supervision of Jitendra Malik from the University of California at Berkeley in 2011, and a BTech in Computer Science and Engineering from IIT Kanpur in 2006. In the past I have enjoyed working at the University of Amsterdam, AWS AI, Google, INRIA, Microsoft Research, the CLSP center at JHU, and Oxford University. My research is funded by the National Science Foundation (including a CAREER), NASA, as well as awards from Climate Change AI, Facebook, NVIDIA, and Adobe.

My research focusses on computer vision with a particular emphasis on algorithms for high-level recognition. My goal is enable cheap and robust sensing of the visual world using cameras powered by computer vision. For an overview of my research take a look at my recent publications, CV and research statement (visualized as a word cloud). I am also on Google scholar.
