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.

Research Interests

My research lies at the intersection of theoretical computer science and cryptography, with a focus on secure multiparty computation. I am particularly interested in how information-theoretic methods, combinatorial techniques, and geometric tools can be used to characterize the feasibility, efficiency, communication, and round complexity of cryptographic protocols. Recent work includes a general framework for solving linear inequalities over high-dimensional convex sets, with applications to secure function evaluation (FOCS 2025, FOCS 2022, TCC 2023), drawing on tools from real algebraic geometry; tight characterizations of the feasibility and rate of secure non-interactive simulation of correlations (TCC 2022, EUROCRYPT 2022), using Fourier analysis; and optimal constructions of coin-tossing protocols under various adversarial models (TCC 2019, ISIT 2021), leveraging martingale theory, entropy, and communication complexity.
