Biotechnology safety analysis applied to risk management and science policy decision-making. Environmental and ecotoxicological risk assessment. Food safety risk assessment. Soil and environmental chemistry applied to exposure assessment, efficacy, environmental monitoring, environmental toxicology, and environmental fate of xenobiotics. Applied soil solution chemistry.
Biotechnology risk assessment with emphasis on uncertainty analysis using probability and possibility theory. Ecological consequences of pollen and gene flow. Transgenic protein fate and behavior in relation to human and environmental safety. Risk management and communication. Earlier research centered on method development and application of soil solution compositional analysis to problems of environmental monitoring and ecological exposure assessment. Directed a discovery support effort to evaluate efficacy/environmental fate relationships of newly discovered pesticides emphasizing kinetics of concurrent sorption/degradation processes, elucidation of solute flow paths through the soil profile, methods for enhancement of retardation/degradation within the soil profile, modeling evaluation of environmental fate and ecotoxicity in ground and surface water.
