Bio

I am currently at NVIDIA working as Deep Learning - A pplied Research Scientist. Prior to that I obtained my Ph.D from Texas A M University in Electrical and Computer Engineering. I was advised by Dr. Krishna Narayanan. Prior to joining Texas A M University in 2011, I received my Bachelor of Technology in Electrical Engineering from Indian Institute of Technology Madras, Chennai, India in 2010. From 2010-11 I worked as an associate engineer at Caterpillar India. During the summer of 2015 I did a summer internship at Intel, Santa Clara in the wireless team. In my free time I passinately follow and play football (the European one, not the Soccer as referred in USA), and occassionally cricket and tennis too.
