I am an aquatic toxicologist that is interested in understanding the ecological consequences associated with emerging contaminants. Emerging contaminants of interest include microplastics, pharmaceuticals, and personal care products. I utilize physiological and ecological approaches to examine their effect. I also utilize analytical chemistry to understand their occurrence and distribution in aquatic habitats and biota.
