Hysteresis, reentrance, and glassy dynamics in systems of self-propelled rods

Sept. 30, 2015

Non-equilibrium active matter made up of self-driven particles with short-range repulsive interactions exhibits collective motion and nonequilibrium order-disorder transitions.

Motor protein accumulation on antiparallel microtubule overlaps

Sept. 24, 2015

Biopolymers serve as one-dimensional tracks on which motor proteins move. These phenomena have inspired theoretical models of one-dimensional transport, crowding, and jamming.

Multiscale polar theory of microtubule and motor-protein assemblies

Jan. 30, 2015

Microtubules and motor proteins can form new “bioactive” liquid-crystalline fluids that are intrinsically out of equilibrium and which display complex flows and defect dynamics.

Regulation of chromosome speeds in mitosis

Sept. 6, 2013

When chromosomes are being separated in preparation for cell division, their motions are slow relative to the speed at which many motor enzymes can move their cellular cargoes and at which microtubules depolymerize.

Biophysics of filament length regulation by molecular motors

April 16, 2013

Regulating physical size is an essential problem that biological organisms must solve, but it is not well understood what physical principles and mechanisms organisms use to sense and regulate their size.

Linear aggregation and liquid-crystalline order: comparison of Monte Carlo simulation and analytic theory

Dec. 31, 2010

Many soft-matter and biophysical systems are composed of monomers that reversibly assemble into rod-like aggregates that can then order into liquid-crystal phases.
