I use a combination of laboratory experiments, numerical simulations
and mathematical modelling to examine atmosphere-ocean,
environmental and industrial fluid flows.
The experiments are designed to serve two purposes:
to explore and develop new mathematical models of the
dynamics of fluid flows that are not
easy to simulate (for example, particle laden flows), and
to determine how the results of numerical simulations
differ from experiments thereby to
derive improved mathematical models (for example,
of the parameterization of turbulence).
My research is focused on issues of mixing and transport
in stratified fluid flows examining, in particular,
nonlinear effects of internal gravity waves,
the interaction between
internal gravity waves and turbulence, and the evolution of gravity
currents and plumes in stratified flows. Recent work is studying
particle transport by turbulence, breaking waves and plumes.
