I am a Cryptographer at Niobium Microsystems, where I work on developing acceleration solutions for cryptographic primitives, while ensuring privacy and security guarantees on data. Prior to joining Niobium, I was a Postdoctoral Associate and Adjunct Faculty at the University of Connecticut, hosted by Prof. Benjamin Fuller.
Even before, I was a Research Scientist in the Applied Cryptography group at TCS Research and Innovation lab, Mumbai. I completed my Ph.D. from the Department of Computer Science and Engineering at the Indian Institute of Technology, Madras. I was very fortunate to be advised by Prof. C. Pandu Rangan. The focus of my Ph.D. thesis was on building secure and efficient proxy re-cryptographic protocols.
I am broadly interested in cryptography, security and blockchain technology. During my Ph.D., I interned with Prof. Giuseppe Ateniese (Stevens Institute of Technology USA), Prof. Kouichi Sakurai (Kyushu University Japan) and Dr. Vorapong Suppakitpaisarn (University of Tokyo Japan). I was also associated with 0Chain Inc. USA, where I explored applications of proxy re-encryption in blockchains.
