Research Profile

Researcher in applied analysis, numerical simulation, continuum mechanics, and thermodynamically consistent modelling. I am particularly interested in mathematical structures that make complex coupled systems computable, robust, and interpretable across applications in physics and engineering.

Project

DFG SPP 2171: Dynamic Wetting of Flexible, Adaptive, and Switchable Substrates

Mathematical modeling and simulation of substrate-flow interaction using generalized gradient flows

The goal of the project "Mathematical modeling and simulation of substrate-flow interaction using generalized gradient flows" is the thermodynamically consistent description of dewetting phenomena by gradient structures and corresponding generalizations, so that numerical stability is guaranteed by implementing appropriate models. In particular, phenomena at moving contact lines with dynamic contact angles on corresponding complex substrates (adaptive, flexible, switchable) shall be understood in detail. For this purpose, phase-field models and sharp-interface models for viscoelastic substrates with finite strain and also phase separation in the vicinity of contact lines are now being considered in this follow-up proposal.
