Applied Physics and Applied Mathematics

David E. Keyes is the Fu Foundation Professor of Applied Mathematics in the Department of Applied Physics and Applied Mathematics at Columbia University. He has authored or co-authored over 100 publications in computational science and engineering, numerical analysis, and computer science, and has delivered over 300 invited presentations at universities, laboratories, and industrial research centers. With backgrounds in engineering, applied mathematics, and computer science, Keyes 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. Newton-Krylov-Schwarz parallel implicit methods, introduced in a 1993 paper he co-authored, are now widely used throughout engineering and computational physics, and have been scaled to thousands of parallel processors. Keyes has received numerous awards for his teaching and research, most recently the Sidney Fernbach Award 2007. A SIAM Visiting Lecturer since 1992, Keyes became the Vice President-at-Large of SIAM in January 2006. At Columbia, he is faculty advisor to the local student chapter of SIAM.
