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 the design and analysis of concretely efficient MPC primitives to realize functionalities of practical relevance. Find my latest resume here.

I can be reached at ykondi at ccs dot neu dot edu.

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 am spending summer 2020 interning with the crypto research group at Novi/Facebook. I spent summer 2019 visiting Claudio Orlandi at the Aarhus Crypto Group.
