About

I am a passionate pure mathematician in the world of cryptography. During my Ph.D., I worked on designing secure outsourcing protocols for verifiable computations under the guidance of Prof. R Jothi Ramalingam. After my Ph.D., I worked with Dr. R Kabaleeshwaran on secure post-quantum digital signature schemes from lattices. I am currently an Institute Postdoctoral Fellow, working with Prof. Monosij Maitra at IIT Kharagpur.
