After receiving her diploma in mathematics from TUM in 1997 ('summa cum laude'), Miriam Mehl completed her doctorate ('summa cum laude') in the interdisciplinary area of biological wastewater treatment in 2001. She finished her habilitation in the TUM Department of Computer Science in summer 2010, and is involved in several projects in the fields of computational fluid dynamics (CFD), simulation of fluid-structure interactions, and high-performance computing. From 2002 onwards, she was the head of the CFD Group at the Department for Scientific Computing in Computer Science at TUM. This group works with a strong focus on numerically and hardware-efficient algorithms for PDE solvers on high-performance computing architectures.
Since 2013, Miriam Mehl has held the position of a professor at the University of Stuttgart’s Institute for Parallel and Distributed Systems. She is head of the Institute for the Simulation of Large Systems.

Research Interests
Miriam Mehls research topics are in the field of Scientific Computing with a special focus on fluid dynamics related applications. The major aim is to combine mathematical and computer science methods in order to achieve numerically and hardware efficient simulation software. This concerns both the simulation program itself but also the embedding into an application context, that is preprocessing, geometry description, and grid generation one the input side and data interpretation and visualisation on the output side but also the embedding in larger contexts such as coupled multi-physics simulations and interactive simulations (computational steering). Since solvers for partial differential equations are typically data-intensive applications, low memory requirements and efficient data access algorithms are of particular importance and not trivial to achieve for state-of-the art numerical methods such as multigrid solvers on adaptive grids with their complex data dependencies. For multi-physics problems, the challenges are to find flexible and efficient tools for code coupling to be able to reuse existing software and to develop stable numerical coupling strategies that work even with black-box solvers for the single-physics components.
