Dr. Steven G. Perry

My research is focused on the study of atmospheric boundary layer flows as they relate to the near-field transport, dispersal, and deposition of atmospheric pollutants. Much of my work at the Agency has been directed toward the development of applied computer algorithms for simulating pollutant movement and fate, many of which have been adopted by the agency for formal regulatory analyses. This has included the development of EPA’s current refined regulatory models for rural and urban areas (AERMOD model), complex terrain applications (CTDMPLUS model) and the methodologies for estimating impacts from open-pit surface coal mine operations, and applications of agricultural pesticides (AgDRIFT model). For the past eight years I have been the team science lead at EPA’s Fluid Modeling Facility. Recent laboratory studies have been designed and conducted to investigate  flow, turbulence and dispersion in urban canopies. Current and near future research will be particularly focused on improving our understanding of the complex flows around urban and suburban roadways through our laboratory studies and in the development of improved numerical modeling tools for roadway exposures.
