I am a Research Scientist at Visa Research. I was a Post-doctoral Researcher at EECS, UC Berkeley hosted by Sanjam Garg during Fall 2015-Spring 2017 where I was affiliated with Crypto and Theory research groups. My research encompasses all aspects of Cryptography and Security and their interplay with Theory of Computation.

In October, 2015 I received my PhD in Computer Science from Aarhus University, Denmark, where I was a PhD Fellow (August, 2012 – August, 2015) supervised by Jesper Buus Nielsen at the Crypto Group led by Ivan Damgård. I spent the final year of my PhD at Northeastern University, Boston visiting Daniel Wichs.

I obtained my Master of Technology in Computer Science from Indian Institute of Technology, Kharagpur (in 2011) supervised by Abhijit Das and Bachelor of Engineering in Electronics and Telecom. from Jadavpur University, Kolkata (in 2008).
