SELECTED CONSULTING PROJECT EXPERIENCE:
U.S. EPA, OPP, Environmental Fate of Pesticides, Staff Scientist
Edit all environmental fate studies and make sure that the data generated by the primary reviewer comply with EPA guidelines. Extracts technical data from studies on the environmental fate of pesticides into a searchable database. Evaluated and summarized chemical and biological data pertaining to the fate and transport of pesticides in terrestrial and aquatic ecosystems, and on the impact of pesticide use on ground and surface water. Conducted primary reviews and evaluation of more than 80 studies on the environmental fate of more than 31 pesticides. Reviewed data include laboratory hydrolysis; laboratory photodegradation in water, soil, and air; laboratory biological degradation under aerobic and anaerobic conditions. Conducted database searches and literature analyses on the fate, transport and ecotoxicity of selected pesticides. Created chemical structures of various pesticides and their transformation products using the ISIS program.
U.S. EPA, OPPTS, Ecological Risk of Pesticides, Staff Scientist
Determined adequacy of study design with respect to compliance with EPA guidelines and policies. Conducted primary reviews and evaluation of more than 82 studies on the environmental ecotoxicity of more than 21 pesticides. Reviewed data include LC50 determinations for aquatic invertebrates, oysters, fish, and beneficial insects; seedling emergence and vegetative vigor of terrestrial plants; toxicity testing of aquatic plants; LC50 and reproduction success of avian species; and soil microbial community toxicity tests.
