I'm a postdoctoral researcher in cryptography (Research Fellow is the official designation) at the School of Computing at National University of Singapore, advised by Prof. Prashant Nalini Vasudevan. I completed my graduate studies in cryptography at the Computer Science & Engineering Department at Stony Brook University, while advised by Prof. Omkant Pandey. I got my undergraduate and masters degrees (majoring in mathematics) at the Indian Institute of Science, being mentored by Prof. Bhavana Kanukurthi and Prof. Himanshu Tyagi.

I am broadly interested in several aspects of cryptography and their underpinnings to theoretical computer science. I am most familiar with work relating to black-box interactive proofs, MPC, and their concurrent variants, extending to protocol design for other similar primitives. Recently I have been closely exploring two broad directions: (1) Post-quantum notions of security, focusing on code-based assumptions. (2) Notions of cryptographic hardness and their connections to complexity theory, and also their `direct' use in constructions of cryptographic primitives, with an eye towards finding new plausibly quantum-resistant sources of hardness.

Additionally, I maintain an active interest in the complexity of and cryptography involving quantum uncloneability, a burgeoning discipline in quantum computing. I am also interested in the use of cryptography in digital systems with obvious real world applicability.

I will be moving soon in November to join as faculty at [to be announced soon]. Please reach out if you would like to explore opportunities in this regard.
