Site Environmental Risk Assessments: Conducted environmental risk assessments at numerous US and international industrial sites.
Environmental Stewardship: For multiple global companies, developed methods to compile, score, and rank hazards associated with their products.
Pharmaceutical Environmental Risk Assessments: For multiple pharmaceutical companies, evaluated the environmental risk associated with the societal use of their products, compliant with either European (EMA) or US (FDA) risk assessment guidelines. As part of several assessments, oversaw collection of additional environmental fate and toxicity test data.
Pharmaceutical Safety Screening: At the request of a global pharmaceutical company, developed environmental risk assessment screening protocols for their active pharmaceutical ingredients (API).
Regulatory Comment: On behalf of companies, trade associations, and non-profits, provided comments on proposed regulations, such as revisions to the CT’s Remedial Standard Regulations, NY’s proposed regulation for hydraulic fracturing, and San Juan County’s (WA) proposed revisions to critical ordinances for wetlands and fish and wildlife habitat conservation areas.
Endocrine Disruptor Assay Development: At the request of a pharmaceutical company, developed a targeted in vitro screening assay to evaluate the potential estrogenicity of their products. For the Massachusetts Institute of Technology’s Sea Grant program, developed in vitro assays to evaluate the presence and potential effects of pesticides in Cape Cod coastal waters.
Endocrine Disruptors: Served as co-author and lead technical expert on the Integrated Summary Report (ISR) of the Invertebrate (Mysid) Two-Generation Toxicity Test being proposed as a Tier 2 testing assay under US EPA’s Endocrine Disruptor Screening Program.
