About Us

Welcome to the webpage of the Baumeier Research Group at Eindhoven University of Technology (TU/e). We are part of the Centre for Analysis, Scientific Computing, and Applications (CASA) of the Department of Mathematics and Computer Science, as well as of the Institute for Complex Molecular Systems (ICMS).

On these pages, you can find information about our research activities, publications, and group members. We are an interdisciplinary group, with diverse backgrounds comprising mathematics, solid-state physics, chemistry, biology, or nanotechnology engineering.

Our research is focused on the development and application of multiscale simulation approaches for the study of complex molecular materials. A core activity concentrates on problems related to modeling of charge and energy transfer processes in soft matter systems, with relevance to energy research. Other research lines include, e.g., studies of (disorderd) assemblies of biomolecules and super-coarse-grained modeling of soft granular materials.

Typically, we employ large scale computer simulations linking quantum chemistry, classical Molecular Dynamics at all-atom and coarse-grained levels, and rate-based models. We are actively developing methods in these areas with the biggest emphasis currently being on the adaptation of Many-Body Green’s Functions Theory (GW-BSE) for molecular systems and its use in hybrid quantum-classical simulation setups. All methods are implemented in the XTP library of the open-source VOTCA package.

Yesterday's @TUe_MCS CASA Day saw us giving a Topical session on "Modeling of Electronic Processes in Complex Molecular Systems", talking about concepts, quantum chemistry, and Machine Learning. Very happy about how it went and proud of Gianluca's and Onur's performances.

I joined Eindhoven University of Technology as Assistant Professor  in September 2015. The research activity in my group is devoted to the development and application of multiscale simulation techniques for the study of electronic transport processes in soft matter. Our models combine techniques from computational chemistry, statistical physics, and mathematics and will allow for the analysis of the interplay between molecular electronic structure and material morphology, relevant for many opto-electronic device properties or bio-molecular processes. I believe that my role as a teacher is not only to pass on information to my students. It is more difficult, both for the teacher and for the student, to also teach them how to think. In evolving fields such as physics, chemistry, or materials science, factual knowledge changes rapidly but the ability to reason is what allows us to master these changes.
