Brief Biography

A hearty Welcome! 

I am an Associate Professor at Dept. of Computer Science & Automation (CSA), EECS Division, 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, Security Group at EECS, AI @ IISc at IISc and Robert Bosch Centre for Cyber-Physical Systems at IISc.

Prior to coming to IISc, I spent three 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).

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