Professional Experience

Harvard University School of Engineering and Applied Sciences (August 2012 Present)

Research Assistant

Utilizing Eulerian (GEOS-Chem Adjoint) and Lagrangian (STILT) transport models to discern the spatial

footprint of TES and GOSAT satellite observations of methane.

Comparing inversions derived from a Lagrangian and Eulerian framework with simulations conducted in support

of the NASA Carbon Monitoring System (CMS).

University of Colorado at Boulder Dept. of Mechanical Engineering (January 2010 August 2012)

Research Assistant

Investigated how a modeled column concentration of a short-lived species (NH3, NO2, SO2, and HCHO) is

in uenced by non-local emissions.

Researched the e ects of recent urbanization on surface level air quality in eight African cities (Akure, Bamako,

Johannesburg, Kinshasa, Kumasi, Lagos, Louga, and Segou).

Responsibilities include developing, applying, and validating an approach to determine non-local in uences

using the GEOS-Chem Adjoint model as well as conducting simulations with the forward model.

Princeton University Geophysical Fluid Dynamics Lab (GFDL) (May 2011 August 2011)

Summer Intern, NOAA Hollings Scholar

Examined the long-term cyclone frequency and air quality impacts in the Northeastern U.S. and found statis-

tically signi cant decreasing mid-latitude cyclone frequencies in future climate scenarios.

Responsibilities include using a python software package to identify mid-latitude cyclones on over 2500 years

of simulations including GFDL CM3 simulations contributing to the IPCC AR5 report.

Lawrence Berkeley National Laboratories (May 2010 August 2010)

Research Assistant, SURE Fellow

Used the WRF-STILT (Weather Research and Forecasting Stochastic Time Inverted Lagrangian Transport)

model to calculate particle trajectories and improve the methane emission estimates for the CalGEM Project.

Conducted a sensitivity analysis and general model evaluation that compared the estimates from the two model

setups. The results were used to validate the robustness of methods employed.

Shell Oil Company (August 2011 May 2012)

Senior Design Project

Developed numerical models and experimental models to estimate regions in deadleg piping systems prone to

corrosion from wet NH4 Cl.

Validated ANSYS Fluent models against an experimental model with the following operating parameters: 100

psig, 10 cfm, 620 F working uid, and 15,000W of heat transfer.
