    Ph.D. Chemistry (May 2017), Howard University, Washington, D.C. Dissertation Title: Modeling Regional & Global Tropospheric Ozone: Gas Phase Chemical Mechanisms & Respiratory Health Effects

    B.S. Chemistry (May 2011), Howard University, Washington, D.C.


    5/2015 - 12/2015

    Graduate Research Fellow, Advanced Student Program

    National Center for Atmospheric Research (NCAR), Boulder, Co

    • Added new chemistry to RACM2 to improve its performance for simulating organic aerosol precursors and to convert it to a mechanism that can be used for global atmospheric chemical modeling, which will be called GACM
    • Implemented the GACM initial conditions to the S-Box model to observe how global gas phase chemical mechanisms can help produce better air quality model forecasts for the regional scale.
    • Implemented GACM in the WRF-Chem model, so it could be used to provide global scale boundary conditions for regional scale modeling by the WRF-Chem model with RACM2.
    • Compared simulations made with the WRF-Chem meteorological air quality model with GACM and RACM2 chemistry to measurements; especially for ozone and particulate matter.

    Desert Research Institute, Reno, Nevada, Reno, Nevada

    • Mean data, collected at the Desert Research Institute, of the major VOCs found in the South Coast Air Basin was used by the S-box model and evaluated under various NOx conditions.
    • Used the S-box model to make thousands of simulations and then produced the output data of various species studied in throughout the project (i.e. ozone, HOx, NOx, PAN, etc.).
    • The model output produced from the S-box model was analyzed by creating isopleths using the Sigma Plot program. The isopleths were used to observe the trends of the species over a period time and how the concentrations of those species increased or decreased due to variations of ozone and NOx concentrations.

    Graduate Research Assistant

    NOAA Center for Atmospheric Sciences (NCAS), Washington, D.C.

    • Researching the effects that volatile species in the atmosphere have on poor air quality in regional and global areas and the resulting respiratory health effects.
    • Collecting model output of the volatile species to be analyzed by using a zero-dimensional atmospheric chemistry model (S-box) coupled with the Regional Atmospheric Chemistry Mechanism (RACM2) and three-dimensional Weather Research & Forecasting Model coupled with chemistry (WRF-Chem).
    • Analysis of simulations from air quality models using EPA’s BenMAP-CE (Environmental Benefits Mapping & Analysis Program-Community Edition) to estimate the health effects due to poor air quality.

    Senior Research Scientist

    Science Systems and Applications, Inc., Greenbelt, MD

    • Evaluate the near real-time GEOS system that includes analyses and five-day forecasts of the chemical composition. The main focus is on the evaluation of near surface ozone and oxides of nitrogen, as well as, other components that affect air quality.
    • Monitor chemical and meteorological diagnostics produced from the GEOS-CF (composition forecast) model on a daily/monthly basis.
    • Develop new metrics that adapt output from the GEOS system to be applied quantitatively to the study of impacts on human health; applying data to BenMAP.
    • Perform simulations with the GEOS system that identify uncertainties in surface pollution distributions and which target improvements in the overall system performance.
    • Monitor severe air quality events (i.e. agricultural/forest fires) that occur across the globe and compare satellite and surface observational to GEOS-CF model data; assess any major/minor differences.
    • Creates monthly summaries that included the current monitoring status of various chemical species and meteorological fields produced from the CF model, status of the model, current field mission support, and validation of the model based upon comparisons to satellite and surface observational data.
