About Me

I am currently a PhD student under Dr. Arpita Patra at CSA, IISc. Before this, I completed my M.E in Computer Science and Engineering (CSE) from CSA, IISc. My research interests primarily include Secure Multi-party Computation and Distributed Computing. More specifically, I am interested in finding solutions to intriguing questions related to feasibility and efficiency of MPC protocols under different computational and network models. The research areas I have worked on so far include Secret Sharing, MPC with small number of parties and Byzantine Agreement. In my free time, I love reading novels and watching movies.
