About Me

I am currently pursuing my Master's in Computer Science from Indian Institute of Science, Bangalore. I am working under Dr. Arpita Patra and I am associated with the Cryptography and Information Security Lab. My broad research interest is Cryptography and I am working in Secure Computation. I have previous experience with cryptocurrencies, mainly Bitcoin.
Currently my main focus is on Oblivious Transfer Extension and 2PC protocols, using Garbled Circuits. I have also been working with Dr. Ashish Choudhury in the area of Distributed Computing, more specifically the Consensus Problem for Directed Graphs. I spend my leisure in photography,gaming and watching movies.
