I am an environmental organic chemist who has been working with the USGS since 2004. I have a BS in Chemistry from the University of Alabama in Huntsville (1999) and a MSPH in Environmental Health Science from the University of South Carolina (2003). My current research focuses on the occurrence, fate and effects of current-use pesticides and pesticide degradates in the environment. I am a member of the Toxic Substances Hydrology Program's Pesticide Fate Research Team and co-lead for the Amphibian Research and Monitoring Initiative's Pesticide Project.

My Science Topics
My USGS Science Strategy AreasUnderstanding Ecosystems & Predicting Ecosystems Change
The Role of Environment and Wildlife in Human Health
Pesticides and Aquatic Organisms
As a co-lead on the Amphibian Research and Monitoring Intiative's Pesticide Project, I am interested in the fate and effects of current-use pesticides on amphibian populations. My key research interest include:
Understanding the potential link between pesticides, other stressors and amphibian declines
Assessing the effectiveness of constructed wetlands as viable amphibian habitats
Assessing potential links between pesticides and diseases in amphibian populations
