Experience

Staff Scientist	Carter Ledyard & Milburn LLP (July 2009 – Present). Manages all aspects of pesticide related projects to register technical and end-use products for US and international clients. Conducts data assessments to determine the nature and value of studies submitted by pesticide registrants. Manages the placement, conduct and submission to EPA of studies needed to secure US registrations for these products.
Staff Scientist	Keller and Heckman LLP (June 2006 – June 2009). Responsible for managing the regulatory and technical aspects of pesticide related projects for the purpose of state and federal registration, legal support, product development and enforcement issues. Designs, plans, reviews, and monitors product chemistry, residue chemistry, and environmental fate studies, as well as environmental and human exposure and risk assessments. Supports US and international clients for conventional pesticides, biopesticides, biocides and biotechnology products.
Senior Consultant	ChemReg International, LLC (April 2000 – June 2006). Responsible for managing the regulatory and technical aspects of pesticide chemistry projects for the purpose of state and federal registration, legal support, product development and enforcement issues. Designs, plans, reviews, and monitors product chemistry, residue chemistry, and environmental fate studies, as well as environmental and human exposure and risk assessments. Supports US and international clients for conventional pesticides, biopesticides, and biotechnology products.
Senior Chemist	Jellinek, Schwartz & Connolly, Inc. (April 1990 – March 2000). Responsible for managing the technical aspects of environmental fate and residue chemistry studies for state and federal pesticide registration, reregistration, Special Reviews, and other pesticide regulatory matters. Designs, plans, reviews, and monitors animal and plant metabolism studies, crop residue studies, soil dissipation studies, animal feeding studies, and other physical/chemical transformation studies. Performs statistical analysis on data from these studies. Conducts environmental modeling on the fate of chemicals in the environment for the purpose of predicting environmental concentrations. Conducts aquatic and drinking water risk assessments. Manages junior staff in reviewing and monitoring these studies.
Principal Scientist, Environmental Chemistry	Sandoz Crop Protection Corporation, Des Plaines, Illinois (March 1986 - April 1990). Supervised the environmental chemistry group that designed, conducted, and reported environmental fate and plant metabolism studies required for state and federal pesticide registration. Conducted environmental fate modeling studies to predict residues in soil, ground and surface waters, air, and animal and plant tissues (crop residues). Also designed, planned, and supervised field residue studies. Specialized in vitro studies, such as plant tissue culture studies were also conducted.
Group Leader, Environmental Chemistry	Velsicol Chemical Corporation, Chicago, Illinois (August 1981 - February 1986). Supervised technical aspects of the environmental chemistry group that designed, planned, and conducted environmental fate and plant metabolism studies as well as studies on the effects of pesticides and industrial chemicals on microbes and higher plants.
Chemist, Environmental Chemistry	Velsicol Chemical Corporation, Chicago, Illinois (August 1978 - July 1981). Conducted studies on the effects of industrial chemicals and pesticides on microbes and higher plants, metabolism of pesticides by microbes and higher plants and environmental fate studies.
Research Assistant, Soil Science Department	North Carolina State University, Raleigh, North Carolina (February 1973 - July 1978). Conducted research on a nitrogen metabolism in higher plants and mechanism of nitrate reduction and transport by plants and microbes.
Food Technologist, Agricultural Research Service	United States Department of Agriculture, Beltsville, Maryland (October 1972 - January 1973). Performed applied research on the physical and microbial properties of meat in order to identify methods to improve meat quality.
