Research Profile
The main research interests are in the theory and computer simulation of self-organization in nonlinear biological and ecological systems far from equilibrium, in particular
- stochastic and deterministic theory of complex spatio-temporal pattern formation in systems with interactions, diffusion and advection,
- theory of density- and space-dependent diffusion coefficients and reaction rates,
- rapid diffusion and advection processes, perturbation-theoretical methods,
- sensitivity analysis of dynamical systems,
- applications to biochemical reaction systems, differentiation of cell communities and biomorphogenesis, nucleation phenomena, enzyme kinetics, biosensorics as well as population dynamics,
- analysis of coupled models of hydrodynamics, transport and nonlinear biological and biochemical interactions with applications to marine ecosystem and water-quality modelling,
- pattern formation in hybrid population-dynamical models,
- fractal patterns of motion of rule-based model components,
- theory of bioinvasions with applications to the spread of infectious diseases and invasive plants,
- noise-induced spatiotemporal pattern formation and dynamics.
