Education:
- M. S. Chemical Engineering, University of California, Los Angeles
Thesis title: "The Dry Deposition of Polynuclear Aromatic Hydrocarbons to Rough Surfaces and Vegetation," Advisor: Professor Sheldon Friedlander.
Areas of Expertise:
Performing scientific research involving computer modeling of air chemistry, with an emphasis on ozone and other oxidants, for a variety of regulatory and research applications. Use of chemical and meteorological principles to solve complex and varied problems related to air quality issues. Experience in planning, budgeting, managing, and executing research programs to conduct research on issues in atmospheric chemistry. Background in writing FORTRAN programs, and in implementing a variety of other software packages, including statistical, graphical, and GIS programs.
Individual Research Mission:
To participate in developing and implementing improved, multipollutant, multiphase descriptions of atmospheric chemistry in order to answer questions relating to the production and control of secondary photochemical pollutants in the troposphere. To use these mechanisms to analyze and improve our understanding of the behavior of complex chemical interactions that occur in the atmosphere.
Relevance of Research to Agency Mission:
When we understand the processes by which secondary pollutants, such as ozone, air toxics and organic particulate matter are formed in the atmosphere, we will be able to better define their sources. This will help us to develop strategies for decreasing the concentrations of atmospheric pollutants in an efficient, accurate, and cost effective manner. By understanding the complex interactions of multiple, co-existing pollutants, we will be better able to develop efficient strategies that will address a number of pollutants simultaneously, and avoid situations where actions we take for one pollutant might adversely affect concentrations of other pollutants.
Experience:
1993 to current - Physical Scientist and Acting Branch Chief of the Process Modeling Research Branch. Performed research on photochemical mechanisms for application in regional and global air chemistry modeling. Analyzed production pathways for atmospheric oxidant species, reactants, and intermediates, and their temporal concentration distributions in atmospheric models. Obtained and analyzed new chemical mechanisms and facilitated their incorporation into EPA's research and regulatory models.
1992-1993 - Environmental Programs Group and the North Carolina Supercomputing Center, MCNC. Lead a team of scientists responsible for applying the Urban Airshed Model for use in the ozone State Implementation Plan process for the state of North Carolina.
1990-1991 - Radian Corporation. Implemented regulatory air quality models, including the Industrial Source Complex Model (ISC2), the Fugitive Dust Model (FDM), and the Human Exposure Model (HEM), to perform both screening and refined simulations.
1984-1990 - Research Engineer, Atmospheric Sciences Department, Battelle Pacific Northwest Laboratory. Analyzed pollutant chemical reaction, transport, and remov
