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


Welcome, Dibyendu!

We welcome Dibyendu Dutta to the team! Dibyendu joins us from Supreet Saini's group at IIT Bombay. We are excited about him joining as first postdoc in the group and look forward studying phage host range evolution in biofilms together with him.

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,...

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.
