Impact of population spatial structure on mutant fixation probabilities, from models on graphs to the gut

We are delighted to announce that the next seminar of TheBioNet will take place on Wednesday, 28 April, 2021, 16:00-17:00, over Zoom
Speaker: Anne-Florence Bitbol (EPFL)
Title: Impact of population spatial structure on mutant fixation probabilities, from models on graphs to the gut

Microbial populations often have complex spatial structures, with homogeneous competition holding only at a local scale. Population structure can strongly impact evolution, in particular by affecting the fixation probability of mutants. Anne-Florence Bitbol will first discuss a general model for describing structured populations on graphs. Then she will show that the specific structure of the gut with gradients of food and bacterial concentrations can increase the fixation probability of neutral mutants, which can have consequences for the diversity of the microbiota.

About us
The aim of TheBioNet is to build a community of researchers working on diverse topics in mathematical and theoretical biology in Western Switzerland. Every semester we are holding seminars every two weeks where we have invited researchers from Western Switzerland working in theoretical and mathematical biology.
