Brief Biography

A hearty Welcome! 

I am an Assistant Professor at Dept. of Computer Science & Automation (CSA), Indian Institute of Science Bangalore, India. Together with my students, I am part of the Cryptography and Information Security (CrIS) Lab. I am also associated with the Theoretical Computer Science Group at CSA.

Prior to coming to IISc, I spent three and half wonderful years as post-doctoral fellows at University of Bristol, UK (hosted by Prof. Nigel Smart), ETH Zurich, Switzerland (hosted by Prof. Ueli Maurer) and Aarhus University, Denmark (hosted by Prof. Ivan Damgaard) and as visitors at Indian Statistical Institute Kolkata, India (hosted by Prof. Bimal Roy) and Bar-Ilan University, Israel (hosted by Prof. Yehuda Lindell).

I spent five and half colorful years of my student life at IIT Madras doing PhD (with Prof. C. Pandu Rangan) and Master of Science by Research (with Prof. Sukhendu Das).

Born in a remote village of West Bengal, I graduated from Haldia Institute of Technology and completed my initial studies from Kumarpur Hateswar High School and Gobardhanpur Pramathanath Vidyayatan, West Bengal.

I work on Cryptography and Secure Distributed Computing.

Apart from science, I have artistic inclinations towards photography and writing.
