Active Clustering, Fluctuations and Stresses in Living Cells
Mathematical Biology| Speaker: | Madan Rao, Raman Research Institute/National Centre for Biological Sciences, Bangalore, Ind |

Description
The material of the living cell is subject to active stresses
arising from a cytoskeletal meshwork which is driven out of equilibrium
by the action of motors and polymerization/depolymerization. I will describe
the coarse grained dynamics of this system, and its implications in
two cellular contexts : (i) Cortical actin dependent clustering of molecules
on the cell surface and its consequences to sorting and signaling, (ii)
Buckling
and stiffening of a filament in an active contractile medium.
