ATENEO DI QUALITÀ ACCREDITATO ANVUR - FASCIA A

Martedì 12 aprile ore 14, seminario Prof. Kevin John Painter "Models for chemosensitive movement: the impact of flow and phenotypic structure"

Speaker: Prof. Kevin John Painter (Politecnico di Torino)

Data e ora:  Martedì 12 aprile, ore 14

Luogo: Sala Riunioni, III piano, plesso di Matematica e Informatica

Titolo: Models for chemosensitive movement: the impact of flow and phenotypic structure

Abstract: The gathering of cells or animals into large groups provides one of nature's most spectacular examples of self-organising behaviour. To achieve this within a fluid environment, though, could involve confronting strong and turbulent flows. Cells and animals can neutralise flows by swimming upstream, a phenomenon termed rheotaxis. But is it always advantageous to use rheotaxis? Adapting the well known Keller-Segel framework, we look at the effects of flow both in the presence and absence of rheotaxis, teasing out scenarios under which group formation and maintenance is enhanced. Optimised behaviour results not when rheotaxis is always on, but modulated according to local population density.
