Biophysical Modeling: Events

Listed below are upcoming talks and events:

July 5  – Karol Makuch, 10 am. 7th floor of the Flatiron Institute. “Homogenization theory in complex liquids”.

Abstract: Theoretical prediction of macroscopic flow properties of complex liquids is challenging even in the simplest case of suspension of spherical particles. There are a few available theories to calculate viscosity of a complex liquid based on its microscopic structure. I will discuss those theories and show why the problem of homogenization is still developing and another approach is on demand. At the end of my talk I will discuss a prospective direction in the field which have recently emerged. In this approach homogenization is performed by numerical simulations of only a few particles which are immersed in the complex liquid described by its effective viscosity. Importantly, the effective viscosity is a function of the wave vector.

July 7  – John F Brady, 10 am. 7th floor of the Flatiron Institute. “Forces, Stresses and the (Thermo?) dynamics of Active Matter”.

Abstract: A distinguishing feature of many living systems is their ability to move—to be active. Through their motion living systems are able self-assemble: birds flock, fish school, bacteria swarm, etc. But such behavior is not limited to living systems. Recent advances in colloid chemistry have led to the development of synthetic, nonliving particles that are able to undergo autonomous motion by converting chemical energy into mechanical motion and work. This intrinsic activity imparts new behaviors to active matter that distinguish it from equilibrium systems. Active matter generates its own internal stress, which can drive it far from equilibrium, and by so doing active matter can control and direct its own behavior and that of its surroundings. In this talk I will discuss our recent work on active matter and on the origin of a new source of stress that is responsible for self-assembly and pattern formation in active matter systems.
