Hadi Kharaghani

Hadi Kharaghani is a Professor of Mathematics at the University of Lethbridge, specializing in combinatorial design theory with a focus on Hadamard matrices and orthogonal designs. His research explores the intricate relationships between discrete structures, algebraic methods, and applications in coding theory and graph theory.

Education:

• B.Sc. in Mathematics, University of Tehran (1966)
• M.Sc. in Mathematics (Probability), Pahlavi University (1969)
• Ph.D. in Mathematics, University of Calgary (1975)

Research Interests: His work centers on Hadamard matrices, orthogonal designs, and their applications. A notable contribution includes the introduction of "Bush-type" Hadamard matrices, which have shown connections to the energy of graphs. His investigations span classification problems, existence criteria, and constructions of these combinatorial objects.

Grants and Funding: Kharaghani's research is supported by the Natural Sciences and Engineering Research Council of Canada (NSERC). Recent grants include:

• "Orthogonal designs, Hadamard matrices and applications" (NSERC, $110,000 over 5 years)

Publications: His recent work (2020–2023) delves into advanced topics such as projective plane-related Hadamard matrices, optimal ternary codes, and quasi-balanced weighing matrices, published in leading journals like Journal of Combinatorial Theory, Series A and Designs, Codes and Cryptography.

Editorial Roles: He serves as an Honorary Editor for the Journal of Combinatorial Designs and as a member of the Editorial Board for Contributions to Discrete Mathematics.
