Beschreibung
I will present two stories about the physics of multicellular
systems.
The first part of my talk will be about the mechanics of tissue
folding. Taking the inversion of the green alga Volvox as a model
developmental event, I will highlight the role of mechanical forces
during development, and show how a model in which the cell shape
changes driving inversion appear as variations of the intrinsic
geometry of an elastic shell reproduces inversion quantitatively.
This will lead me to discuss what one might term - with the nod to
Turing that is customary in the field - the noisy basis of
morphogenesis.
The second part of my talk will be about systems that are
multicellular only in the etymological sense: I will present recent
results on the ecological role of phenotypic variation and phenotypic
switching in communities of competing microbes.
