# David E. Keyes

David E. Keyes is a Senior Associate to the President of King Abdullah University of Science and Technology (KAUST) and the Director of the Extreme Computing Center at King Abdullah University of Science and Technology (KAUST). He was the inaugural Dean of the Division of Computer, Electrical, and Mathematical Sciences and Engineering (CEMSE) at KAUST and remains an adjunct professor in Applied Physics and Applied Mathematics at Columbia University and an affiliate of several laboratories of the U.S. Department of Energy. With backgrounds in engineering, applied mathematics, and computer science, he works at the algorithmic interface between parallel computing and the numerical analysis of partial differential equations, across a spectrum of aerodynamic, geophysical, and chemically reacting flows.

## Professional career

Keyes graduated summa cum laude in Aerospace and Mechanical Sciences from Princeton in 1978 and earned a doctorate in Applied Mathematics from Harvard University in 1984. He served on the faculties of Yale, Old Dominion, and Columbia Universities before taking up his current post in 2009. He is the author or editor of more than a dozen federal agency reports and member of several federal advisory committees on computational science and engineering and high performance computing. As of January 2022, his works have been cited 12180 times, and he has an h-index of 46.
