I received my Ph.D. in Electrical and Computer Engineering at the University of Southern California, where I was advised by Prof. Shrikanth Narayanan and Dr. Panayiotis Georgiou. My thesis investigated the efficacy of Probabilistic Graphical Models and Deep Learning Sequence models at understanding how humans express behaviors such as affect, empathy and depression through conversational language.

Prior to USC, I obtained my M.S. from Carnegie Mellon University and my B.Tech. from Jawaharlal Nehru Technological University Hyderabad.
