Current Position: Air Dispersion Modeler, Nevada Division of Environmental Protection

Research Interests: My interests include: the examination of atmospheric dispersion both numerically and experimentally. The numerical aspect spans from Lagrangian dispersion models to simpler Atmospheric dispersion models (ADE). Comparing these model results with measurements from the field is very rewarding. My research has implemented these models and methodology to understanding the problem of near source deposition of PM10 generated from traffic on unpaved roads.

I am also interested in the modeling of turbulence. This includes the implementation of simple mixing length models to more complex Large Eddy Simulation (LES). The application of these methods Atmospheric flows to smaller scale engineering flows is of great interest to me.

Environmental Fluid Dynamics Lab

Understanding Flows in the World Around Us

The work done at the Environmental Fluid Dynamics Laboratory at the University of Utah attempts to further the understanding of transport phoenomena in the natural world. To this end, the laboratory employs a variety of state of the art scientific investigation techniques including: large scale field measurements (both Urban and Natural Environment), numerical modeling and simulation, and laboratory scale measurements. The laboratory is situated in beautiful Salt Lake City, Utah in the foothills of the Wasatch mountains.
