Education and early career

He holds a Ph.D. in Applied Mathematics, at the University of Karlsruhe (1987) and a Postdoc at SFB 123, University of Heidelberg (1987 – 1991). Wittum’s scientific interests lie in developing software architectures, fast solvers for large systems of equations, multiscale numerics and homogenization, discretization, inverse modeling, and optimization enabling numerical methods for high dimensional problems. His work also focuses on numeric geometry and visualization. His research contributes to advance in Medicine and Neurosciences as well as Economics and Environmental Sciences.

Why modeling and simulations?

A general approach to modeling and simulation of problems from empirical sciences, in particular, using HPC. Foci are the development of advanced numerical methods for modeling and simulation in particular fast solvers like multigrid methods, allowing the application to complex realistic models, the development of corresponding simulation frameworks and tools, and the efficient use of top-level supercomputers for that purpose. These methods and tools are applied to problems from computational fluid dynamics, environmental research, energy research, finance, neuroscience, pharmaceutical technology and many more.

Why KAUST?

After 25 years as a professor at several universities in Germany, I was interested in a new challenge. KAUST’s vision as a hub for interdisciplinary research with a strong computational component convinced me to come to KAUST. As a computational and computer scientist, my home there is CEMSE.
