Research interests
From plasmids to tree networks, I am interested in the evolution of ecological interactions and how adaptive behaviour affects communities. Besides statistical approaches, I'm particularly interested in the design, development and analysis of individual-based models to investigate such systems. My research interest spans the following subjects:
| Approaches | Individual-based Ecology and Modelling | Methods of Statistics and Computer Science |
| Area | Plasmid Biology and Microbial Evolution | Ecology of 'Plant-Soil-Atmosphere' Systems |
A current focus of my research is the propagation of antibiotic resistances in aquatic environments. The prefered platform of antibiotic resistence genes are plasmids, which constitute important genetic elements for bacterial adaptation and diversity. I use mathematical models such as systems of ordinary differential equations, cellular automaton and individual based models to investigate mechanisms that influence plasmid transfer and persistence under various ecological conditions.
