Hi there! I received the B.Tech and M.S. degrees in Mechanical engineering from Indian Institute of Technology Madras (IIT-M) and Stanford University, in 2014 and 2016, respectively. I am currently doing my Ph.D. in Mechanical Engineering at Stanford University. My research work is primarily at the intersection of energy and electronics. Contact: |
