Research Assistant Professor

Research Areas: Environmental/Molecular, Marine Toxicology

My research focuses on the study of man-made and natural toxins in the marine environment and their effects on the metabolic activities of marine organisms. Biochemical and health effects following exposure to anthropogenic compounds, contaminants and toxins can drastically alter the development, metamorphosis, reproductive capacity or the ability of exposed organisms to utilize nutritional resources. The consequences of exposure may be human health effects related to ecosystem exposure and reduced water quality, declines in available habitat and decreases of vital fisheries (both finfish and shellfish). Current research themes include (1) examination of the molecular and biochemical pathways involved in endocrine production, metabolism and environmental disruption, (2) the effects of anthropogenic exposure on uptake, distribution and metabolism including oxidative stress in marine/estuarine species (3) determining the effects and consequences of exposure to antifouling compounds and booster biocides on non-target species and (4) the characterization of detoxification pathways (cytochrome P450s) in marine species.
