Pratyay Mukherjee
Cryptography and Computer Security Researcher
Hi! I’m Pratyay Mukherjee. Welcome to my academic (and non-academic) webpage! In my native language Bengali my name spells as প্রত্যয় মুখার্জী.
Bio
Currently I am working as a Principal Researcher at Hashgraph. I am also a Visiting Scientist / Guest Faculty at Indian Statistical Institute, Kolkata.
Earlier I was a Senior Director of Research at Supra Research during June, 2022 to Sept, 2025; a Senior Research Scientist at Swirlds Labs during January, 2022 to June 2022; a Research Scientist (and later a Senior Research Scientist) at Visa Research since March, 2017 to January, 2022; and 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. Recently I have been mostly focusing on applications of Cryptography in the Payment and Blockchain space.
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).
