Brian Sutton

Brian Sutton is Associate Professor of Mathematics at Randolph-Macon College in Ashland, VA. His primary research areas are numerical linear algebra and random matrix theory. He is the First Place recipient of the Fourteenth Leslie Fox Prize in numerical analysis for his work on computing the CS (Cosine-Sine) matrix decomposition, and his current work on the CS decomposition is funded by NSF grant DMS-0914559. With Alan Edelman, he founded the stochastic operator approach to random matrix theory, which reinterprets finite random matrices as discretizations of a select few continuous operators, moving the field into the domain of functional analysis. At Randolph-Macon, Brian has taught courses on numerical analysis, differential equations, probability, and statistics, as well as an interdisciplinary course on epidemiology.
