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


Welcome, Emma!

We welcome Emma Tollafield to the team! Emma will be a technician in the group, supporting the project on host range evolution in biofilms.

New preprint on chirality in colonies

What drives chirality in E. coli colonies? We, Andrés Aranda-Díaz, KC Huang, myself and a number of colleagues went out to see whether it is twisting of single cells during growth. But again and again, the experiments did not allow us to make this conclusion. Finally,...

Project ideas for EPSRC-funded PhD Studentships at Exeter

We are welcoming applicants to Exeter's EPSRC DTP who want to pursue their PhD in our group and those of wonderful colleagues. You will need to apply with a project proposal, and here are two ideas:   Modelling viruses in crowded biological environments – from...

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.
