CHeSs - Complex Heterogeneous Systems
Group
Our general motivation is to develop a reliable, theoretical, and computational framework for transport and
reactions in complex heterogeneous multiphase systems based on mathematical, physical, and thermodynamic principles.
We combine rigorous, mathematical and physical modelling strategies with state-of-the-art methodologies such as
variational and thermodynamic analysis, optimization, gradient flows, statistical mechanics, stochastic analysis, and novel computational approaches allowing for the reliable and efficient discretisation
of complex heterogeneous multiphase systems.
