Graduate Student

Biography

I received my bachelors degree in computer science and engineering at Indian Institute of Technology, Kharagpur in 2004. Now I am a fourth year graduate student in the Machine Learning Department 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.
