I am an Assistant Professor in the CSE department at IIT Delhi. My research interests span the broad area of data analytics with particular focus on graph indexing and mining, social network analysis, querying and mining spatio-temporal data, and bioinformatics. The tag-cloud of my paper abstracts provides an accurate representation of my research interests.

I graduated from the Computer Science department of University of California, Santa Barbara in March, 2012. Prior to joining IIT D, I worked as Assistant Professor at IIT Madras for close to three years and at IBM Research, Bangalore for a year and a half. During my grad school days, I worked on querying and mining molecular databases in the DBL lab under the supervision of Prof. Ambuj Singh.

Internships: I am NOT offering any short-term projects. My apologies if I don't respond to your email.
