Update

I am currently a post-doctoral researcher at the Cryptography and Privacy Engineering (ENCRYPTO) group of Technical University of Darmstadt under the supervision of Prof. Thomas Schneider. My new webpage is available here.



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) and Ph.D in CSE under the guidance of Dr. Arpita Patra. During my doctoral studies, my research focused on 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 boredom strikes, you may visit World Through My Eyes.
