DR. CODY J. HOWARD is the 2011 winner of the New Investigator Award sponsored by the ACS AGRO Division and DOW Agrochemicals. He received his Ph.D. in environmental engineering in 2009 from the University of California at Davis under the direction of Dr. Michael Kleeman. While at UC Davis, he developed a field method for determining ozone formation potential of livestock, silage, and pesticide inert emissions using a transportable smog chamber. The field data was coupled with simulated chemistry mechanisms to predict the effect of agricultural emissions on ozone concentrations in California’s San Joaquin Valley.
Dr. Howard’s discovered that corn silage is a major contributor to ozone pollution in the region, which has increased research efforts by others in California and within the USDA. His data are being utilized in regional transport models to evaluate the confluence of rural and urban emissions on ozone concentrations and are being used by the California Air Resources Board to develop new regulations concerning pesticide and animal emissions.
Dr. Howard is currently a post doctoral researcher with the Agricultural Research Service division of the United States Department of Agriculture in Beltsville, Maryland working with Drs. Cathleen Hapeman and Laura McConnell. His current work focuses on utilizing computer models and field data to predict the fate and transport of pesticides, particulate matter, ammonia, and VOCs from agricultural operations and to discern their effects on air quality and ecosystem health in the Chesapeake Bay region. He will be presenting his recent work entitled “Pesticide Emissions Model: Evaluation of performance in predicting pesticide emissions from the Chesapeake Bay region” during the AGRO symposium, Agriculture and Air Quality: Emissions Measurements and Models. The research concerns validation of the Pesticide Emissions Model (PEM) against a multi-year, high-resolution dataset of pesticide emissions carried out at USDA-ARS, Beltsville by Drs. John Prueger and Timothy Gish. After validation, PEM was used in conjunction with land use data to estimate emissions from pesticide use in the Chesapeake Bay Region.
Dr. Howard recently represented the USDA at a NIST workshop on Aerosol Metrology and Climate and serves as the liaison between ARS and US EPA Atmospheric Modeling and Analysis Division for the PEM. A member of ACS since 2009, he will be co-chairing the aforementioned symposium.
