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 here.

News & Updates:

April 10, 2014: I will be offering Digital Image Processing (E9 241) in Fall 2014.

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. 

February 12, 2014:  (prospective summer interns) If you are interested in doing a summer internship with me, please apply through the internship program run by the Indian Academy of Sciences (http://www.ias.ac.in/)I won't be able to respond to direct internship applications.

February 4, 2014:  I will be giving a tutorial on "Semidefinite Relaxation" at the upcoming SPCOM conference.

February 3, 2014:  I joined the Department of Electrical Engineering at the Indian Institute of Science.
