Computer simulations of processes at the molecular level greatly improve our understanding of the behaviour of biological processes, chemical reactions, and material properties. I'm an applied mathematician working on new algorithms to model and simulate molecular systems, leveraging the power of both data science and physical insight. I'm currently head of the DMP Group at MPI DCTS Magdeburg.

  Research Topics

TT-Network Koopman Methods for Molecular Simulation Molecular simulations lead to huge data sets requiring automated methods to extract equilibrium and kinetic properties. Highlights of our research in this domain include a variational approach, tensor methods, randomized kernel methods.
TT-Network Error Theory for Koopman Modeling Determination of provable error bounds for Koopman models remains a key challenge for data-based dynamical systems research. Some of our recent results cover stochastic systems with ergodicity and kernel methods. Improved results for general ergodic systems were described here.
Greedy Search Data-driven Coarse Graining Learning reduced models that can be simulated more efficiently is an essential step towards scaling up molecular simulations. Our results include a sparse identification method, spectral learning, and error bounds.
