Select Projects

Site Ecological Risk Assessments:  Conducted ecological risk assessments at numerous US and international contaminated sites.

Ecological Injury Assessment and Causation Analysis:  Conducted ecological injury assessments and causation analyses for ecological receptors exposed to a variety of chemical and non-chemical stressors at different sites.

Environmental Stewardship:  For global companies, evaluated the environmental safety of their products to support sustainability goals.

Pharmaceutical Environmental Risk Assessments:  For pharmaceutical companies, evaluated the environmental risk of their new drugs to support market approval, compliant with either European (European Medicines Agency [EMA]) or US (Food and Drug Administration [US FDA]) guidelines.  As part of several assessments, oversaw the collection of additional environmental fate and toxicity test data.

Emerging Contaminants:  In the context of a wide variety of projects, provided consulting and expert support related to the environmental safety of various contaminants of emerging concern, such as endocrine disruptors, pharmaceuticals, 1,4-dioxane, PFAS, microplastics, etc.

Endocrine Disruptors:  For companies, trade associations, and government (US EPA), provided technical expertise related to the topic of endocrine disruption.
