Dr. Brasseur pursues two research tracts: (1) the study of turbulence physics, turbulent combustion, atmospheric boundary layer (ABL) dynamics and wind turbines using direct and large-eddy simulation (LES), and (2) physiology, mechanics and medicine of the gastrointestinal (GI) tract and drug delivery. Area (1) includes nonlinear turbulence interscale dynamics with/without chemistry, turbulent shear flow and modulation by polymer additives, turbulence dynamics of the lower troposphere, fundamentals of LES. Dr. Brasseur lead a DOE effort to develop HPC models of nonsteady wind turbine response to atmospheric turbulence. Area (2) integrates neurophysiology and mechanical function to advance clinical diagnostics in GI medicine. Dr. Brasseur couples muscle-fluid motions, mixing and absorption using mathematical modeling, lattice-Boltzmann computer models and physiological data analysis. These methods are currently applied to analyze drug dissolution and absorption in vivo vs. in vitro.
