interested in Cryptography

Hello!

I am a postdoctoral researcher at the Crypto Group at Aarhus University hosted by Prof. Claudio Orlandi. I did my PhD at Bar-Ilan University under the supervision of Prof. Carmit Hazay, and my Master's degree in CSE specializing in Cryptography from IIT Bombay, where I did my Master's thesis under Prof. Manoj Prabhakaran.

Research

My PhD research deals with multi-party computation (MPC), specifically outsoursed computation and MPC-as-a-Service. My PhD thesis focusses on designing garbled circuits based solutions for the same. My other research areas include designing MPC protocols for a wide range of settings and the design and application of garbling schemes.

My Master's thesis under the guidance of Prof. Manoj Prabhakaran is titled 'CellTree', an architecture for distributed data repositories that aims to serve as an alternative to blockchain technology. It is an original design drawing from existing literature on distributed ledger technology and looking to not only solve the scalability issues in blockchains but also allow for verifiable dynamic data storage.
