Sivaram Narayan

Sivaram Narayan is a Professor of Mathematics at Central Michigan University (CMU), affiliated with the Department of Mathematics in the College of Science & Engineering. He holds a Ph.D. from Purdue University (1988), an M.S. from the University of Michigan (1981), and a B.S. from the University of Madras, India (1974).

His research focuses on Operator Theory, Matrix Analysis, and Frame Theory, with significant contributions to linear algebra, functional analysis, and graph theory. He has supervised 72 undergraduate researchers, many of whom co-authored papers in refereed journals. Notable awards include the 2009 Outstanding Research Award and 2004 Outstanding Teaching Award from CMU's College of Science & Technology, as well as a 2004 Research Professorship.

Narayan has led multiple National Science Foundation (NSF) grants, including REU (Research Experiences for Undergraduates) sites from 2003–2025, fostering undergraduate research in algebra, analysis, and matrix theory. His work on minimum semidefinite rank, frame robustness, and graph theory has advanced the understanding of matrix properties and combinatorial optimization.

He has authored/co-authored over 50 publications, including works on composition operators, frame theory, and graph complements. His research often bridges pure mathematics with applications in signal processing and combinatorial frameworks.
