About Me

I am currently a Ph.D. candidate at the Center for Visual Information Technology at IIIT-Hyderabad. I work with Prof. P. J. Narayanan on topics related to Computational Photography and Machine Learning. My main area of research is Epsilon Focus Photography, which deals with capturing and processing multi-focus images, depth from focus, measurement of focus/defocus-blur and post-capture control of depth-of-field. I am also broadly interested in Computer Vision, Computer Graphics and High Performance Computing.
