I am a fifth year Ph.D. student at LTI advised by Prof. Jaime Carbonell and Prof. Judith Klein-Seetharaman. I am interested in the broad area of machine learning for computational biology. My current research focus is on transfer learning methods for protein-protein interaction prediction.


Before computational biology I have had not-so-brief stints in the areas of Information Retrieval for structured data (during my Masters at IIT Bombay) and Information Extraction from unstructured data (at Yahoo! Labs). I worked with S. Sudarshan at IIT Bombay and with Rajeev Rastogi, Srinivasan H. Sengamedu and Shailesh Kumar at Yahoo! Labs. I have also interned at IBM research labs, Delhi with Prasan Roy and Venkatesan Chakravarthy.

In summer of 2012, I interned with Microsoft Research, Redmond and I worked on a problem in the broad area of Genetics. I was a TA for Machine Learning in the Spring of 2012, with Roni Rosenfeld. In the Spring of 2011, I TA-ed Data Mining and Information Retrieval with Jaime Carbonell.

Some of my hobbies are reading science-fiction, birding, photography, kayaking, playing board-games. I have trained in Kathak, an Indian classical dance form. I also love to ice-skate and ski (still a novice) in Pittsburgh winters. These days I'm learning the piano.
