Prof. Marek Behr obtained his Bachelor's and Ph.D. degrees in Aerospace Engineering and Mechanics from the University of Minnesota in Minneapolis. After faculty appointments at the University of Minnesota and at Rice University in Houston, he was appointed in 2004 as a Professor of Mechanical Engineering and holder of the Chair for Computational Analysis of Technical Systems at the RWTH Aachen University. From 2006 until 2019, he was the Scientific Director of the Aachen Institute for Advanced Study in Computational Engineering Science, focusing on inverse problems in engineering and funded in the framework of the Excellence Initiative in Germany. Since 2019, he is the speaker of the International Research Training Group 2379 "Modern Inverse Problems" operated jointly with the University of Texas at Austin. Behr advises or has advised over 60 doctoral students, and has published over 80 refereed journal articles and a similar number of conference publications and book chapters. Behr is one of the main developers of the stabilized space-time finite element formulation for deforming-domain flow problems, which has been recently extended to unstructured space-time meshes. He is a long-time expert on parallel computation and large-scale flow simulations and on numerical methods for non-Newtonian fluids. He is a member of several advisory and editorial boards of international journals, President of the German Association for Computational Mechanics, and elected member of the Executive Council of the International Association for Computational Mechanics (IACM). He has received the IACM Fellow award in 2014.
