I am a PhD student in MLD within school of computer science at CMU working under Prof. Eric Xing.

My research interests include statistical machine learning, non-parametric Bayesian methods, information retrieval and clustering. I have recently worked on transferring supervision in finite and infinite mixture models (Dirichlet Process) and information retrieval.

I interned at Microsoft Research Redmond in summer of 2014 and got the opportunity to work with great mentors: Rich Caruana,  Evelyne Viegas and Mathew Richardson. I also received the prestigious IBM Fellowship for 2013-2015. I have worked as a researcher for 2 years at IBM Research India from 2009 - 2011. I received my Master of Technology degree in Computer Science from IIT Bombay in 2009.
I did my Master's thesis in Information Retrieval under the guidance of Prof. Soumen Chakrabarti
