Meso-scale turbulence in living fluids
The authors' experimental results for the bacterial flow statistics agree well with predictions from a minimal model for self-propelled rods, suggesting that at high concentrations the collective motion of the bacteria is dominated by short-range interactions.

Topological defects in epithelia govern cell death and extrusion
A mechanism for apoptotic cell extrusion is proposed: spontaneously formed topological defects in epithelia govern cell fate, and the ability to control extrusion hotspots by geometrically inducing defects through microcontact printing of patterned monolayers is demonstrated.

The contact line singularity is overcome by diffusion which is effective over a length scale L about the contact line and derive a scaling form for the dependence of L on system parameters.
Steady-state hydrodynamic instabilities of active liquid crystals: hybrid lattice Boltzmann simulations.
We report hybrid lattice Boltzmann (HLB) simulations of the hydrodynamics of an active nematic liquid crystal sandwiched between confining walls with various anchoring conditions. We confirm the
Transport coefficients of a mesoscopic fluid dynamics model
We investigate the properties of stochastic rotation dynamics, a mesoscopic model used for simulating fluctuating hydrodynamics. Analytical results are given for the shear viscosity and the friction
Modeling contact angle hysteresis on chemically patterned and superhydrophobic surfaces.
This work investigates contact angle hysteresis on chemically patterned and superhydrophobic surfaces, as the drop volume is quasistatically increased and decreased, and identifies analytically the advancing and receding contact angles on the different surfaces.
Liquid crystal microfluidics for tunable flow shaping.
It is shown that the liquid crystalline microfluidic flow can be fully steered from left to right of a simple microchannel by applying transverse temperature gradients.
Instabilities and topological defects in active nematics
We study a continuum model of an extensile active nematic to show that mesoscale turbulence develops in two stages: i) ordered regions undergo an intrinsic hydrodynamic instability generating walls,
Spontaneous flow states in active nematics: A unified picture
Continuum hydrodynamic models of active liquid crystals have been used to describe dynamic self-organising systems such as bacterial swarms and cytoskeletal gels. A key prediction of such models is
