Welcome To My Website

Starting September 2015, I have joined Allen Institute for Artificial Intelligence as a Research Scientist. I received Ph.D. from Language Technologies Institute, School of Computer Science, Carnegie Mellon University in August 2015. During Ph.D. (August 2009-15) I was co-advised by Prof. William Cohen and Prof. Jamie Callan, in the area of Information Extraction and Information Retrieval.
I have completed my Masters in 2007 from IIT Bombay under the guidance of Prof. S. Sudarshan. I worked in Google India from 2007-2009 as a Software Engineer.

Research Interests

Thesis Topic

Thesis document [PDF]
My thesis porposes a general framework ``Exploratory Learning'' that tackles learning scenarios which are superset of semi-supervised learning in the sense that some of the classes might be unknown to the algorithm, and can be discovered from the unlabeled data. More information: link.
