About

I am currently a senior project associate in the Department of Computer Science and Engineering at the Indian Institute of Technology Kharagpur, working with Dr. Monosij Maitra. Previously, I was a Visiting Fellow at the Advanced Computing and Microelectronics Unit, Indian Statistical Institute, Kolkata, under the supervision of Prof. Sourav Chakraborty. I completed my Ph.D. in Computer Sciences at the National Institute of Science Education and Research (NISER), Bhubaneswar, under the supervision of Prof. Deepak Kumar Dalai.

I am primarily interested in analyzing the algebraic and structural properties of mathematical objects used to build and evaluate cryptographic primitives.

Research Interests

  • Symmetric-Key Foundations and Finite Fields
  • Zero-knowledge proofs and algebraic-friendly cryptographic primitives
  • Lattice based digital signatures
  • Mathematical aspects of Lattices
