Ph.D., University of Tennessee
Special Awards/Honors: 
National Academy of Engineering Member, SIAM Fellow

G.W. "Pete" Stewart is a Distinguished University Professor Emeritus of computer science.

Stewart is a world-renowned expert in computational linear algebra. He has made fundamental and highly cited advances in the analysis of rounding error in numerical computations, perturbation of eigensystems, generalized inverses, least squares problems, and matrix factorizations. He has developed efficient algorithms for the singular value decomposition, updating and downdating matrix factorizations, and the eigenproblem that are widely used in applications.

Stewart has published six textbooks, which are models of exposition that have educated multiple generations of researchers. His contributions have led to numerous honors, including election to the National Academy of Engineering and being named a SIAM Fellow.

Stewart received his doctorate from the University of Tennessee in 1968.
