I am interested in the exposure and effects of contaminants including current-use pesticides and other endocrine active compounds on fish and wildlife with a focus on amphibian populations.
I am an environmental organic chemist who has been working with the USGS since 2004. My current research focuses on the occurrence, fate and effects of emerging contaminants including current-use pesticides in the environment. I am the lead for the Amphibian Research and Monitoring Initiative's Contaminants Project, the project coordinator of the "EDC effects on fish and wildlife in the Cheseapeake Bay Watershed" project through the Contaminants Biology Program, and a member of the Toxic Substances Hydrology Program's Pesticide Fate Research Team.

Drinking Water and Wastewater Infrastructure Science Team
The team studies toxicants and pathogens in water resources from their sources, through watersheds, aquifers, and infrastructure to human and wildlife exposures. That information is used to develop decision tools that protect human and wildlife health.
USGS Scientists Develop an Interactive Mapping Tool to Visualize PFAS in Tap Water
A new interactive dashboard is available to visualize PFAS measurements for 716 tap water samples collected at select sites across the nation between 2016 and 2021 from private and public supplies.
Improving Understanding and Coordination of Science Activities for Per- and Polyfluoroalkyl Substances (PFAS) in the Chesapeake Bay Watershed
Issue: Per- and polyfluoroalkyl substances (PFAS) have been manufactured and used in a variety of industries in the United States since the 1940s. PFAS are ubiquitous and persistent in the environment and have the potential to have adverse human and ecological health effects. The Chesapeake Bay Program (CBP) partnerships has concerns about how PFAS will affect the Chesapeake Bay ecosystem. The CBP...
Collaborative Science Provides Understanding of Contaminants in Bottled Water-an Increasingly Common Alternate Drinking Water Source
U.S. Geological Survey researchers and public health experts collaborated to determine what contaminants occur in bottled water, which is an increasingly common alternate drinking water source, to broaden their understanding of human exposure to contaminants in drinking water supply chains. Bottled water, like public-supply and private-well tap water supply chains, contained multiple organic...
USGS Integrates Findings about Endocrine-Disrupting Compounds in the Chesapeake Watershed
Issue: Studies in the Chesapeake Bay Watershed have documented the exposure of fish to toxic contaminants including endocrine-disrupting compounds (EDCs) - compounds which can alter normal hormonal function in organisms. Given the importance of fisheries to the economic and environmental health of the Watershed, observed endocrine disruption and fish kills in the Watershed have raised public and...
Inorganic and Organic Chemical Mixtures Detected in both Public and Private Tap Water in Cape Cod, Massachusetts
Multiple detections of regulated and unregulated chemical (inorganic, organic) analytes or elements were detected in both privately and publicly supplied tap water samples from 20 residences in Cape Cod, Massachusetts that share a common source of water.
