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 (I^{2}R),
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.
