Specialist research areas

Biological Fluid Dynamics:

 

Membranes

    • experiments on multicomponent lipid bilayers, involving diffusion and phase separation of lipid domains

Micro-organism dynamics

    • motility of algae and bacteria

Propulsion

    • particularly mechanisms of motion linked to motile cilia in eukaryotes; also model experiments on scallop theorem using driven colloidal particles.

Pulmonary fluid mechanics

    • how flows in mucrociliary tissues are driven by collective beating of cilia; rheology of pulmonary surfactant, and properties of mucus

Complex Fluids:

 

Colloids

    • colloids in two-dimensional arrangements: structure, interactions, rheology; flotation.

Interfacial Flows:

 

Thin films

    • experiments on Langmuir monolayer films

Low-Reynolds-number Flows:

 

Stokesian dynamics

    • Oseen tensor and other descriptions of coupling between moving objects at low Re in collection to motile cilia synchronisation

Micro-/Nano-fluid Dynamics:

 

Microfluidics

    • development of devices for the flow of cells, and control of position and shape of cells - typically these devices allow imaging of many cells at individual cell resolution; some of our devices are "micro-chemostats"

Non-Newtonian Flows:

 

Polymers

    • polymer rheology both in bulk and in interface films

Rheology

    • techniques for microrheology

Viscoelasticity

    • viscoelasticity of colloidal, polymer and novel lipid mesophases

Nonlinear Dynamical Systems:

 

Pattern formation

    • in the context of collective dynamical patterns in cilia; patterns of domains in lipid membranes
