How environmental constraints influence the dynamics of a population and its evolution

News

About the Lab

We are interested in how the physical world shapes the dynamics in biological systems. We currently focus on the role of the environment on the evolutionary dynamics of populations expanding into new habitats.

We use a variety of models, mostly borrowed from physics, simulation techniques and protocols necessary to make quantitative measurements. Our current model system of choice is bacteriophage T7 spreading on a lawn of the bacterium E. coli.
