Calin Chindris
Professor, Director of Graduate Studies
305 Mathematical Sciences Building

Dr. Calin Chindris’ research interests lie at the interface of representation theory of finite-dimensional algebras and geometric invariant theory. His research is focused on theoretical aspects of invariant theory for finite-dimensional algebras as well as applications to Brascamp-Lieb theory in harmonic analysis, the Paulsen problem in frame theory, robust subspace recovery in machine learning, and Edmonds' problem in algebraic complexity.

Since coming to the University of Missouri, Calin’s work has been supported by the Simons Foundation, NSA and NSF. During his graduate career, Calin was the recipient of the Sumner Myers Award for best Ph.D. Thesis in Mathematics and the Wirt and Mary Cornwell Prize in Mathematics at the University of Michigan.
