Email: {first four characters of my first name followed by dot followed by my last name}@gmail.com

I am a Research Scientist at Google. My research interests span topics in machine learning, data-mining and theoretical computer science. Prior to Google, I was a Researcher at Microsoft Research and at Yahoo! Labs.

I obtained a PhD in Computer Science from the University of Southern California under the supervision of David Kempe, and a B. Tech in Computer Science from IIT Delhi. My PhD research focused on algorithms for subset selection and sparse approximation. Prior to my PhD, I also spent several years in the industry (Cortina Systems and  Mahi Networks), where I worked on software stacks for networking and embedded systems.

My work has received a Distinguished Paper Award at the International Conference on Machine Learning (ICML) 2011, a Best Paper Award at the ACM Conference on Web Search and Data Mining (WSDM) 2014, and a Best Paper Honorable Mention Award at the Web Conference (WWW) 2018.
