(I moved to Redmond, WA!)

I joined Microsoft in 2019 after my post-doc in Christina Leslie's group. Prior to this, I did a brief stint at IBM Research, in the Machine Learning group (headed by Naoki Abe) working with Aurelie Lozano and Eunho Yang. I graduated from LTI in Aug 2015, where I was advised by Prof. Jaime Carbonell and Prof. Judith Klein-Seetharaman. I am interested in the broad area of machine learning for computational biology, health and social good problems. My thesis focussed on multitask and transfer learning methods for host-pathogen 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 at Microsoft Research, Redmond and I worked on a problem in the broad area of Genetics with Hoifung Poon. 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 in Pittsburgh winters.
