**Jaap van der Vegt** is Professor in Mathematics of Computational Mechanics, and head of the Chair **Ma**thematics of **C**omputational **S**cience in the Department of Applied Mathematics at the University of Twente.

His research interests are in Numerical Analysis and Scientific Computing. The main focus is on the development, analysis and application of finite element methods for partial differential equations, in particular discontinuous Galerkin methods. Important topics are solution adaptive methods, including a priori and a posteriori error analysis, higher order accurate discretizations, compatible schemes which preserve the mathematical structure of partial differential equations after discretization, and multigrid methods for the efficient solution of algebraic systems resulting from finite element discretizations. Main areas of applications are fluid mechanics, both compressible, incompressible, multiphase and free surface flows, and electromagnetics.
