Research Interests:

My research generally focuses on land-atmosphere interactions, atmospheric boundary-layer (ABL) turbulence, large-eddy simulation (LES), and experimental boundary-layer turbulence studies of flows over canopy transitions in order to better understand lake surface fluxes of mass and momentum, provide more reliable input to lake ecosystem response models, and test LES sub-grid scale parameterizations for ABL simulations over complex terrain.

In particular I am interested to use an interdisciplinary approach to better understand land-atmosphere-lake exchange processes, of momentum, heat, water vapor, and gas constituents in the coupled two boundary layer (lake-atmosphere) system with heterogeneous land cover and topography, which is a particular case of land surface heterogeneity (including canopy and heat transitions). These transport processes are important in engineering and environmental applications, including lake hydrodynamic models, and weather and pollution models. My work includes (or will involve) a combination of experimental work in the SAFL Boundary Layer Wind Tunnel (using hot wire and PIV anemometry), field measurements (using sonic and acoustic doppler anemometry), modeling (using LES), and theoretical development.

Specific questions I am interested to answer include, how does heterogeneous sheltering along lakes affect wind access and how does the spatial and temporal dynamics of surface shear stress affect lake ecosystem dynamics, specifically biogeochemical cycling, surface gas transfer, and carbon storage.
