About Me

I am a graduate research student in the Computer Vision Lab of the College of Information and Computer Sciences, University of Massachusetts, advised by Prof. Erik Learned-Miller. I am interested to work on the intersection of Machine learning methods and Computer Vision. Prior to this I worked as Visiting Researcher in Electronics and Communication Sciences Unit, Indian Statistical Institute, Kolkata. with Prof. Dipti Prasad Mukherjee. I completed my Masters in Computer Science in the year 2015, from the same institute. My primary research interest is in non-linear learning models in Computer Vision. I particularly enjoy working on methods that exploit the local geometry of real world images in a non-linear model, and use statistical models to infer their characteristics. I am also interested in shape representations and predictive modeling. My current research is aimed at the generalized closed-form solution to the pre-image problem in kernel learning.

I am a philatelist and an avid reader. I like absurdist fiction (Franz Kafka), postmodern literatures (Orhan Pamuk) and historical non-fiction. I love the works of Sir P. G. Wodehouse, Sir Arthur Conan Doyle, Satyajit Ray and Roald Dahl. I am also a huge Marvel and DC fan. Besides I am an audiophile and at my leisure I like to play my guitar. I also like to play cricket and football (soccer).
