I am an Assistant Professor in the Department of Electrical Engineering at the Indian Institute of Science. 

Prior to joining the department, I was a research associate in the Program in Applied and Computational Mathematics at Princeton University.

I did my PhD in Computers, Communications, and Information Systems at EPFL, and my Masters in System Science and Automation here at the institute.

You can find a short resume here.

My primary research interest is in signal/image processing, with a focus on algorithms and numerical optimization. 

More recently, I have been working on graph/manifold-based methods for image restoration, and on distributed algorithms for localizing (positioning) large graphs 
arising in molecular conformation and sensor networks. 

A list of some of the research topics that I work on can be found at this link.

News & Updates:

April 24, 2014:  I gave a review talk on matrix completion. This was my first chalk talk.

April 10, 2014: I will be offering Digital Image Processing (E9 241) in August-December 2014. More info at this link.

February 21, 2014: (prospective students from IISc) Please mail me or meet me (EE 204C) if you are interested in research projects on patch-based image restoration, fast algorithms for data-adaptive filtering, sensor network localization, and multiview registration.  In general, I would be happy to collaborate on new ideas in signal/image processing, particularly algorithms and numerical optimization.
