Subject

Prof. Dr. Benjamin Stamm joined the Faculty of Mathematics at the University of Stuttgart in August 2022. Before moving to Stuttgart, he worked at RWTH Aachen University and Sorbonne Université UPMC Paris 6, after conducting research at the University of California, Berkeley, and Brown University. Prof. Stamm has an academic background with a Ph.D. and a master's degree in mathematics from École Polytechnique Fédérale de Lausanne (EPFL).

His research area focuses on numerical analysis, scientific computing, and simulations, in particular efficient discretizations and solvers for partial differential equations (PDEs) and eigenvalue problems, error certification and a posteriori error estimates, reduced basis method, and high-performance computing (HPC) implementations. Prof. Stamm develops scalable numerical methods and algorithms for complex problems in the natural sciences, with many of his research topics originating in computational chemistry and physics. The methods he develops are aimed at certifying the accuracy of computations and improving the efficiency of numerical methods. He also emphasizes the development of modular softwares that enable uniform implementation of these methods.

Prof. Stamm's research is characterized by its relevance to current research topics and applications, its interdisciplinary nature, and its focus on developing efficient and accurate methods that have an impact on various scientific and technical disciplines. The interdisciplinary nature of his work is evident in his collaboration with experts from different disciplines, such as chemists, physicists, and materials scientists.
