Who am I?
I am an Associate Professor in the Department of Computer Science and Engineering, IIT Bombay. I am also part of Centre for Machine Intelligence and Data Science and the Koita Centre for Digital Health at IIT Bombay.
I started working as a faculty member at IITB since July
2013. I defended my PhD thesis in 2010 in the Department of Computer and Information Science and Engineering at the University of
Florida, Gainesville. I have a bachelor's degree in computer engineering from the University of Pune, India, and a master's degree in computer science from McGill University, Montreal, Canada. I worked
as a postdoctoral researcher in the Electrical and Computer Engineering Department at Duke University, Durham, North Carolina between Jan 2011 and July 2012.

Notes for (Potential) Students
I am currently looking out for one or two motivated and enthusiastic PhD/MS students, interested broadly in the areas of "low level image processing", which basically includes
problems such as image filtering and restoration, and different forms of image reconstruction such as tomographic reconstruction, source separation, compression and compressive sensing. Many of these tasks are used in various important steps to pre-process image data to be input for higher level tasks such as recognition or classification. The ideal candidate should have some background/interest in signal processing and statistical/machine learning
methods which are widely applicable in solving the aforementioned problems. If interested, please take a look at our research page below, and email/meet me for any questions. You will be required to apply to the PhD programme of the
CSE department at IITB and go through the procedure (including entrance test and interview if shortlisted) outlined.
Note to students seeking internships: I do not have any open positions for summer/winter research internships at this point of time.
I receive an overwhelming number of requests
for internships or summer projects, and I am simply unable to answer them.
