Michael J. Tsatsomeros

Michael J. Tsatsomeros is a Professor in the Department of Mathematics & Statistics at Washington State University (WSU), affiliated with the College of Arts and Sciences. His academic journey includes positions at the University of Regina (Canada), University of Wisconsin, and the Indian Institute of Technology-Madras. He holds a Ph.D. from the University of Connecticut (1990), an M.Sc. from Concordia University (1986), and a Diploma in Mathematics from the University of Patras, Greece (1984).

His research focuses on Linear Algebra and Matrix Analysis, with emphasis on nonnegative matrices, numerical range, and applications in dynamical systems, control theory, and AI. He has supervised numerous Ph.D. and Master’s students, including notable advisees such as Samir Mondal, Hung Le, and Pietro Paparella. His work has been recognized with awards like the 2024 Tom & Julie Lutz Teaching Excellence Award and the 2021 Excellence in Advising Award.

Key publications include studies on P-matrices, Cayley transforms, and semimonotone matrices, often appearing in Linear Algebra and its Applications and Electronic Journal of Linear Algebra. He co-authored textbooks like Matrix Positivity (2020) and Linear Algebra and Matrix Methods (2024). Tsatsomeros serves as an Advisory Editor for Electronic Journal of Linear Algebra and Associate Editor for Linear Algebra and its Applications.

His grants include the SPARC Collaboration Grant (2019–2021) and NSERC research funding. Beyond academia, his postdoctoral mentorship includes Fei Zhou and Panos Psarrakos, who now hold academic and industry roles. His research bridges theoretical matrix analysis with applied problems in engineering and computer science.
