Harvard is hosting Frank Brown on Tuesday afternoon from 1:45 to 6 PM and
unfortunately no professor has signed up to speak to him :(. Therefore, I
will change the format of meetings and ask students who are interested in
meeting him to reply to me with a 30 min suggested time slot (e.g. 4 to
4:30), instead of everyone being in the same room speaking, so that we can
effectively cover the time he'll be with us.
Also, let me know if you want to come to dinner with him. This time there
will be slightly fewer slots because the Shakhnovich people might come.
Best,
Joel.

Continuum Models for Biomembrane Dynamics 4/25/12 4:00pm MIT Building 4,

Simulation of biomembranes and lipid bilayers over length and time scales
relevant to cellular biology is not currently feasible with Molecular
Dynamics or similarly detailed methods. Barring an unforeseen revolution in
the computer industry, this situation will not soon change. Two aspects of
mesoscopic membrane dynamics will be discussed: in-plane flow/diffusion in
inhomogeneous membrane systems and out-of-plane membrane undulations. Both
problems are treated within the context of stochastic continuum models,
which allow thermodynamically and hydrodynamically consistent access to
length and time scales up to and beyond the micron and second regimes,
using simple numerical methods. Applications to phase separation kinetics
and domain boundary fluctuations in ternary “model membrane” systems,
membrane shape fluctuations above a solid supporting matrix and diffusion
of curved membrane proteins will be discussed.
