Research interests

My current research interests focus on the application of dynamical systems theory and generalized modelling in the field of cellular transport mechanisms and ecology. I develop new techniques to analyse and visualize the stability of dynamical systems.

As a PhD I considered different processes in predator-prey interactions. I investigated how stoichiometric constrains and diseases can affect the dynamics of these interactions. A central task in my work was to analyze the effects of parameter variations on the long-term behavior of the systems under consideration.
