Narrative:
My research over the past 25 years has focused on performing atmospheric modeling and data analysis for a variety of applications relating to air quality dispersion models. This work has included technique evaluations and applications of spatially resolved air quality models for air toxic pollutants in urban areas, and developing user’s manuals and guidance documents. My emphasis during the past five years has been to provide USEPA and the modeling community with better modeling techniques for estimating local-scale impacts (especially mobile sources), and to link these air quality model estimates with human exposure models for use in human health impact studies.
