Graduate Student

Biography

I received my bachelors degree in computer science and engineering at Indian Institute of Technology, Kharagpur. Now I am a third year graduate student in the Center for Automated Learning & Discovery at CMU.

Research Interests

I am interested in fast mining of large and sparse networks. Currently we are trying to model the evolution of social networks over time.
