I am currently a Post-Doctoral Researcher at CISPA Helmholtz Center for Information Security, hosted by Prof. Nico Döttling. My research focuses on public-key cryptography and quantum cryptography.

Previously, I was a Post-Doctoral Fellow in the Department of Computer Science and Engineering, Indian Institute of Technology Delhi, where I worked under the guidance of Prof. Venkata Koppula.

I completed my PhD and MTech degree under the guidance of Prof. Manindra Agrawal in the Department of Computer Science and Engineering, Indian Institute of Technology, Kanpur. During that time, I was actively working on the cryptanalysis of symmetric-key cryptosystems and variants of subset-sum problem.

My Erdős number is 4 (Me -> Shashank K. Mehta -> Jitender S. Deogun -> Zsolt Tuza -> Paul Erdős).
