Computer Science Division
University of California, Berkeley
I am a Post-doctoral Researcher at the Computer Science Division, UC Berkeley hosted by Sanjam Garg. I am affiliated with Crypto and Theory research groups. I am interested broadly in Theoretical Computer Science and specifically in Theory of Cryptography.
In October, 2015 I received my PhD 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 obtained my Master of Technology in Computer Science from Indian Institute of Technology, Kharagpur (in 2011) and Bachelor of Engineering in Electronics and Telecom. from Jadavpur University, Kolkata (in 2008).

I reviewed papers for Crypto('15,'16), Eurocrypt('13,'16,17'), Asiacrypt('13,'14, '15, '16), TCC('13,'16-A,'16-B), PKC('14,'15,'16,'17), SCN('16), Indocrypt('11,'16), Africacrypt('14), IWSEC('13,'14), Inscrypt ('13), IEEE Transactions on Dependable and Secure Computing ('16), IEICE Journal ('16), Design Codes and Cryptography ('16).
While working at ISI, I taught Number Theory in the Regional/National Maths Olympiad camp and also Discrete Maths in the Crypto Internship Program in 2012.
I am a volunteer at Padakshep: A Step towards education!
I tried to locate the crypto groups around the world in The Crypto Map! (not updated recently).
