Active Self-Organization of Actin-Microtubule Composite Self-Propelled Rods
Frontiers in Physics, 2018 Spontaneous self-organization of active matter has been demonstrated in a number of biological systems including bacteria, cells, and cytoskeletal filaments.

Proceedings of the National Academy of SciencesMicrofluidics involves the manipulation of flows at the microscale, typically requiring external power sources to generate pressure gradients. Alternatively, harnessing flows from active fluids, which are usually chaotic, has been proposed as a paradigm for the development of micromachines.

Complex Spontaneous Flows and Concentration Banding in Active Polar Films [PDF]
, 2008 We study the dynamical properties of active polar liquid crystalline films. Like active nematic films, active polar films undergo a dynamical transitions to spontaneously flowing steady-states.

Active Nematics Are Intrinsically Phase Separated [PDF]
Physical Review Letters, 2006 Two-dimensional nonequilibrium nematic steady states, as found in agitated granular-rod monolayers or films of orientable amoeboid cells, were predicted [Europhys. Lett. {\bf 62} (2003) 196] to have giant number fluctuations, with standard deviation proportional to the mean.

Theory of active self-organization of dense nematic structures in the actin cytoskeleton
eLifeThe actin cytoskeleton is remarkably adaptable and multifunctional. It often organizes into nematic bundles such as contractile rings or stress fibers. However, how a uniform and isotropic actin gel self-organizes into dense nematic bundles is not fully ...

GiantA surface in contact with the isotropic phase of a passive liquid crystal can induce nematic order over distances that range from microscopic to macroscopic when the nematic-isotropic interface undergoes an orientational-wetting transition.

Active morphogenesis of patterned epithelial shells
eLife, 2023 Shape transformations of epithelial tissues in three dimensions, which are crucial for embryonic development or in vitro organoid growth, can result from active forces generated within the cytoskeleton of the epithelial cells.

Analytical structure, dynamics, and coarse-graining of a kinetic model of an active fluid
, 2017 We analyze one of the simplest active suspensions with complex dynamics: a suspension of immotile "Extensor" particles that exert active extensile dipolar stresses on the fluid in which they are immersed. This is relevant to several experimental systems,
