Hi,

I obtained my B.Sc (Hons) in Mathematics and M.Sc in Applied Mathematics from Calcutta University, Kolkata. I obtained my Ph.d in 2006 from the Statistics and Mathematics Department of Indian Statistical Institute, Kolkata, India. I was a post-doc at Cryptography & Security Department of Institute for Infocomm Research (I2R), Singapore from June 2006 to February 2008. I was with the Claude Shannon Institute, Maynooth University, Ireland from February 2008 to January 2010 as a Post-doctoral Research Fellow. Currently, I am an associate professor in the Department of Mathematics, Indian Institute of Technology, Kharagpur, India.
