About

My name is Hamid. I am a PhD candidate in the department of computer science at Purdue university working under the supervision of Professor Hemanta K. Maji. My research interests are theoretical computer science and cryptography, more specifically, Information-theoretic Cryptography.
I earned my master's degree, under the supervision of Professor Mohammad Reza Aref and Professor Taraneh Eghlidos, from the department of Electrical Engineering at Sharif University of Technology. There, I was a member of Information Systems and Security Lab (ISSL). I obtained my bachelor's degree in two majors, Electrical Engineering and Pure Mathematics, from Isfahan University of Technology.
