Journal of Fluid Mechanics, 2012 AbstractWe study theoretically the hydrodynamics of a fluid drop containing oriented filaments endowed with active contractile or extensile stresses and placed on a solid surface. The active stresses alter qualitatively the wetting properties of the drop, leading to new spreading laws and novel static drop shapes.

Active Matter, Microreversibility, and Thermodynamics. [PDF]
Research (Wash D C), 2020 Active matter, comprising many active agents interacting and moving in fluids or more complex environments, is a commonly occurring state of matter in biological and physical systems. By its very nature, active matter systems exist in nonequilibrium states.

Active nematic multipoles: Flow responses and the dynamics of defects and colloids
Frontiers in Physics, 2023 We introduce a general description of localised distortions in active nematics using the framework of active nematic multipoles. We give the Stokesian flows for arbitrary multipoles in terms of differentiation of a fundamental flow response and describe ...

RNA polymerase II clusters form in line with surface condensation on regulatory chromatin
Molecular Systems Biology, 2021 It is essential for cells to control which genes are transcribed into RNA. In eukaryotes, two major control points are recruitment of RNA polymerase II (Pol II) into a paused state, and subsequent pause release toward transcription.

Frontiers in Physics, 2022 Recent studies have shown that packings of cells, both eukaryotic cellular tissues and growing or swarming bacterial colonies, can often be understood as active nematic fluids.

Critical phenomena in active matter [PDF]
Physical Review E, 2016 We investigate the effect of self-propulsion on a mean-field order-disorder transition. Starting from a $φ^4$ scalar field theory subject to an exponentially correlated noise, we exploit the Unified Colored Noise Approximation to map the non-equilibrium active dynamics onto an effective equilibrium one.

Learning to control active matter [PDF]
Physical Review Research, 2021 The study of active matter has revealed novel non-equilibrium collective behaviors, illustrating their potential as a new materials platform. However, most works treat active matter as unregulated systems with uniform microscopic energy input, which we refer to as activity.
