Hometown: Salt Lake City

Program: PhD (Graduated December 2013)

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.

Assignments:

Homework #1 (Due 1/18/2006): 1.12, 1.13

Homework #2 (Due 1/25/2006): 3.2, 3.7, 3.9, 3.10 (code should be written for 3.2 & 3.9)

Homework #4 (Due 2/13/2006): 5.2, 5.7 5.15 (code should be written to solve all three problems. This will essentially require you too write a bisection method solver and a false position method solver. Please hand in the following: your code and the solutions. If the question asks for you to graphically determine a root, be sure to include a plot)

Homework #5 (Due 2/22/2006): 6.3,7.4,7.17 (You will need to write a Newton Raphson solver code for 6.3 and a Mueller's method code for 7.4. No code is required for 7.17 although you may use the code you wrote from 7.4)

Homework #6 (Due 3/1/2006): 9.4, 9.8, 9.10 (please write code for problems 9.8 and 9.10)

Homework #10 (Due 4/26/2006): 25.18, 27.2, 27.3 (write code for all three please, use the Euler's method to solve 27.2, for problem 25.18 solve the ODE from problem 25.1 not 25.7, NOTE: 5 points of extra credit will be given if you do solve 25.7. If you are solving problem 25.1 please use a step size h=0.5. Also, for 27.2 if you use Runge-Kutta I will give you 5 extra credit points.)
