About Me

I am a chronic talker, lifelong learner and I love what I do. Born in a remote village of Kerala, I was raised by parents who taught me to chase my dreams. I completed my B.Tech in Computer Science and Engineering (CSE) from College of Engineering, Trivandrum. I've followed my passion into IISc where I completed my M.Tech (Research) in CSE and am currently pursuing my Ph.D under the guidance of Dr. Arpita Patra. My work orbits around Secure Multi-party Computation (MPC), more specifically in the area of MPC for small number of parties with applications to Privacy Preserving Machine Learning (PPML).

I am a recipient of Google PhD Fellowship 2019 for the year 2019. When I'm not working on a fun project in our lab, you may find me touring the city on my cycle with my camera. When boredom strikes, may be watch the World Through My Eyes.
