Rate My Professor Stephanie Alexander

Alexander's research interests include differential geometry, global analysis, Riemannian manifolds with boundary, metric geometry of Alexandrov spaces, isometric immersions, and classical geometry. Key publications feature "An Invitation to Alexandrov Geometry: CAT(0) Spaces" (Springer, 2019, co-authored with Vitali Kapovitch and Anton Petrunin), "Alexandrov Geometry: Foundations" (American Mathematical Society, 2024, with Kapovitch and Petrunin), and "Lorentz and semi-Riemannian spaces with Alexandrov curvature bounds" (2008, with Richard L. Bishop). Other notable works include "The Riemannian obstacle problem" (Illinois Journal of Mathematics, 1987, with I. David Berg and Richard L. Bishop) and papers on warped products of Hadamard spaces, comparison theorems for curves of bounded geodesic curvature, and total curvature in pursuit games. She supervised five Ph.D. theses, served as an editor for the Illinois Journal of Mathematics, frequently visited the Institut des Hautes Études Scientifiques, and led the U.S. team in a cooperative grant with the Steklov Institute in Russia. Her excellence earned the K.-T. Chen Distinguished Mathematical Research Award (2004-2006), the 2014 American Mathematical Society Fellowship for contributions to geometry, exposition, and teaching, and teaching honors including the 1993 Campus and LAS Dean's Awards for Excellence in Undergraduate Teaching and the 1986 Alpha Lambda Delta Outstanding Teacher of Freshmen Award.
