I am performing laboratory experiments and computer simulations of
fluid flows. My work is motivated by industrial, environmental,
and geophysical problems of such complexity that existing numerical
models do not yield reliable results. 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 parametrisation of turbulence).
Presently, my research is focussed on issues of mixing and transport
in stratified fluid flows examining, in particular,
nonlinear interactions between internal gravity waves,
the interaction between
internal gravity waves and turbulence, and the evolution of gravity
currents in stratified flows.
