At Google, I use program analysis to improve the security of software. Before that I was an engineer at Facebook, and a research staff member in the Systems Analysis and Verification (SAV) group at NEC Laboratories America, Inc., Princeton, NJ. I got my Ph.D in Computer Science from the University of Wisconsin-Madison. I went to the College of Engineering, Guindy for my undergraduate degree. I am from Pollachi, a small and lively town in Tamil Nadu, India. Of late, I have taken a liking to photography.
