I am a Ph.D student at Indian Institute of Science (IISc), advised by Dr. R. Venkatesh Babu. I am a member of Video Analytics Lab in Department of Computational and Data Sciences (CDS). Before joining IISc, I worked as a Research Engineer at Duos Technologies, Jacksonville, USA from May 2012 to December 2013. Prior to that, I was a Research Engineer at Honda Research Institute USA, Mountain View, USA from January 2008 to April 2012. I got my MS degree in Computer Science from University of Washington, Seattle, USA in 2008. I got an integrated MS/B.Tech degree (Honors) in Computer Science from International Institute of Information Technology, Hyderabad (IIIT-H) in 2004. More information is in my CV.


My work is in the area of Computer Vision. My main research focus is visual object category understanding via hand-drawn sketches. My recent and on-going research projects have examined novel sketch-based representations and their visualization, methods for visualizing object features from large-category data, eye-gaze based analysis of sketches and Recurrent Neural Network architectures for on-line sketch recognition. My work has also resulted in the first fully automatic approach for fine-grained parsing of object sketches.


In addition to sketch-related research, my work has resulted in a novel semantic-part based benchmarking procedure for state-of-the-art object recognition systems and novel architectures for depiction-invariant, generalized object recognition.
