Ms. Freeman is a Board Certified Toxicologist (DABT) with over 20 years of experience in regulatory toxicology in the fields of pesticides, industrial chemicals, veterinary medicines, consumer products, and food safety. She has a comprehensive knowledge of toxicological requirements as well as a thorough understanding of the nuances of toxicological testing requirements for specific regulations.

Ms. Freeman is adept at project management and working with clients and regulators to develop strategic approaches to addressing human health concerns. She prepares chemical specific adjustment factor and human relevance frameworks for mode of action submissions. Ms. Freeman also prepares maximum tolerated dose assessments, has expertise in dermal absorption testing, and calculation of human dermal absorption factors and refined dermal equivalent doses, chemical hazard and risk prioritization systems for the oil and gas industry, consumer products and industrial chemicals. She monitors toxicological testing programs, conducts laboratory audits, prepares data evaluation reports and OECD study summaries.

Ms. Freeman prepares waivers from toxicological testing requirements for pesticides based on toxicology, structurally similar compounds and risk evaluations. She has experience with EPA's Endocrine Disruptor Screening Program including the submission of other scientifically relevant information (OSRI), study design and monitoring, weight of the evidence (WOE) evaluations, human risk evaluations, thyroid-specific mode of action testing and assessment, as well as ToxCast and EDSP21 evaluations. She conducts and evaluates QSAR assessments for new product development, re-registration, and impurity and metabolite of concern assessments.

Ms. Freeman has expertise in the Toxic Substances Control Act (TSCA) compliance including new chemical notifications (PMNs and LVEs), chemical reporting, regulatory interpretation, and training. She also has expertise in classification under the U.N.'s Globally Harmonized System (GHS) for Classification and Labeling as well as North American Hazard Communication regulations. She has experience with import tolerances, due diligence assessments, data compensation projects, and data gap analyses for pesticides active ingredients and inerts.

In her previous capacities, Ms. Freeman held positions in toxicology and product stewardship, was responsible for the full lifecycle of toxicology for pesticide and industrial chemicals in the US, Canada, and EU including registrations, re-registrations, tolerance petitions, waivers, testing orders, JMPR submissions, position papers and authoritative body representation.
