A hearty welcome to my homepage. I am a fourth year PhD student in the Department of Computer Science, Boston University, working under the supervision of Prof. Ran Canetti. I am fortunate to be part of the amazing BUSec group. In summer 2021, I interned at the Cryptography team of VISA Research. In summer 2022, I am interning at Meta (previously Facebook) as a Research Scientist intern in the Statistics and Privacy team.
Previously, I have completed my Master's degree at the Department of Computer Science, Indian Institute of Science, Bangalore, where I was working under Dr. Arpita Patra in Cryptography and Information Security Lab. I have completed my Bachelor's in Computer Science from Indian Institute of Engineering Science and Technology Shibpur (erstwhile Bengal Engineering College). During my Bachelor's I have worked at the Indian Statistical Institute, Kolkata under the supervision of Dr. Goutam Paul.
I am broadly interested in providing Privacy-Preserving solutions using Multiparty Computation and Zero Knowledge.
