I am a postdoc in the Department of Computer Science and Automation, where I am a part of the Cryptography and Information Security (CRIS) lab. I was fortunate to be advised by Dr. Arpita Patra during my Ph.D at CSA Department, IISc Bengaluru. Prior to that, I obtained my M.Tech degree from NIT Goa.

My broad research area is Secure Multi-party Computation (MPC), with a focus on verifiable secret sharing, broadcast and consensus protocols. I have also worked on MPC for practice with applications such as Privacy-preserving Machine Learning (PPML). During my master's, I have explored the exciting areas of proxy re-encryption and secret image sharing.
