Biography & Research

I work at Google on their data infrastructure team. In my previous life, I was the department head of the data management group at NEC Labs America. I got my doctoral degree in Computer Science from the University of Maryland in 2008. My Ph.D. advisor was Prof. Hanan Samet. I got my bachelor's degree from RVCE, Bangalore. I mainly work on database management problems related to GIS, big data, analytics, and mobility. I have received a few awards for my PhD and subsequent work.

This year I am the PC co-chair of ACM SIGPATIAL GIS 2014 and publicity co-chair of ACM SIGMOD 2015. I am also in the editorial board of Distributed and Parallel Databases journal.
