Unser Profil

At the lab for applied and computational mathematics (ACoM) we pursue mathematical research at the interface of engineering, natural and life sciences. We are eager to foster and stimulate interdisciplinary activities linking fundamental and applied research. In our view mathematical results provide the fundamental source of capability in the solutions of modern technological problems in applied disciplines.

We are part of the Department of Mathematics at RWTH Aachen, with close links to the groups of numerical analysis at IGPM and uncertainty quantification at UQ. Some of our PhD students and Postdocs are associated with the research training group Energy, Entropy and Dissipative Dynamics, the international research training group Modern Inverse Problems, the SNuBIC research unit, the Sparsity and Singular Structures collaborative research center, as well as with the School for Simulation and Data Sciences.

The work is to be conducted within the framework of the DFG-supported project “Simulation of Rare and Transient Events in Rarefied Gas Dynamics” and the research agenda is focussed on the development of novel algorithms within the Direct Simulation Monte Carlo Method (DSMC) to improve aforementioned simulations. These algorithms include particle-particle and particle-surface interactions, particle merging, and sensitivity analysis methods for stochastic particle-based simulations. Practical applications of the research topic include engineering problems in areas of micro-electromechanical systems, aerospace engineering, and semi-conductor manufacturing.
