Welcome!

I am a PhD candidate at Northeastern, where I am advised by abhi shelat.

My research interests lie in the design of novel cryptographic protocols with a focus on secure multiparty computation (MPC). Specifically, I am interested in developing MPC techniques to realize functionalities of practical relevance, such as distributed ECDSA, Schnorr/EdDSA, and RSA without trusted setup. Find my latest resume here.

I graduated with a Bachelor's and a Master's degree from the International Institute of Information Technology, Bangalore (IIITB) in 2017, where I was advised by Ashish Choudhury. I was also supervised by Arpita Patra at the CrIS Lab, Indian Institute of Science (IISc).

I spent summer 2020 (and part-time Fall 2020) interning with the crypto group at Novi Research, where I was hosted by Valeria Nikolaenko. I visited Claudio Orlandi at the Aarhus Crypto Group in summer 2019.
