Research Interests
The backbone of my research is the mathematical modelling of various nonlinear processes with evolution equations or strongly coupled systems thereof and their qualitative study.
Examples include: degenerate/singular diffusion, chemo-/haptotaxis, adhesion, growth, and stochastic perturbations.
The analysis involves well-posedness, regularity, long-time behaviour, as well as other qualitative properties. Main applications are concerned with the mathematical modelling for life sciences.
