Welcome to my homepage
I am an Assistant Professor at the Department of Computer Science and Engineering, IIT Kharagpur. Before joining IIT Kharagpur I was working as a Post-doctoral Fellow at the Cryptography and Security Group, Aarhus University hosted by Jesper Buus Nielsen. I also obtained my PhD from the Department of Computer Science, Aarhus University under the supervision of Jesper Buus Nielsen and Claudio Orlandi. More information about the vibrant Aarhus Crypto group can be found here.
I received my Masters degree from the Computer Science and Engineering Department, IIT Kharagpur under the guidance of Dr. Abhijit Das. Prior to that, I did my B.Tech in Computer Science and Engineering and B.Sc (Honors) in Physics from University Of Calcutta.
Before joining Aarhus University, I worked as a researcher at the R. C. Bose Centre of Cryptology and Security, Indian Statistical Institute and in the Graduate School of Computer Science, Saarland University.
Research
My research interest varies over many aspects of theoretical computer science, with a focus on cryptography and security. Specifically, I am interested in the design and analysis of provably secure "efficient" cryptographic primitives. Currently, I am working on different projects related to secure multi-party computation.
