About Me

I am a 5th year Ph.D. student at the Paul G. Allen school of Computer Science, UW. I work in the Networks and Mobile Systems Laboratory advised by Prof. Shyamnath Gollakota. Previously, I was a research assistant in the Mobility Networks and Systems group at Microsoft Research, India. My research focuses on leveraging the ubiquity of smart devices with wireless sensors, to enable novel applications that can improve the quality of life. Beyond developing new techniques and algorithms, I also strive to deploy our technology at a large scale to make a difference in people's lives.
