Area of Specialization:
 My past work on the analytical and numerical aspects of statistical
closures in turbulence has led to the recent development of Spectral
Reduction, a reduced statistical description of turbulence. The agreement
with full numerical simulations appears to be remarkably good, even in
flows containing longlived coherent structures. Among the practical
applications, such a tool can be used to assess the effect of various
dissipation mechanisms in largeeddy simulations, as a subgrid model, or
even as a substitute for full simulation of highReynolds number
turbulence.
My other research interests include: implicit dealiasing of linear
convolutions, 3D vector graphics, inertialrange scaling laws for
twodimensional fluid, plasma, and geophysical turbulence; nonlinear
symmetric stability criteria for constrained noncanonical Hamiltonian
dynamics; turbulent transport and the role of anisotropy in plasma and
geophysical turbulence; realizable statistical closures; electroosmotic flow;
parcel advection algorithms; exactly conservative integration algorithms;
anisotropic multigrid solvers.
