The Wigginton research group examines the source and fate of emerging contaminants in aqueous systems.  Part of our focus is on human pathogenic viruses; in particular, we 1) seek improved virus detection methods, 2) aim to better understand the types and concentrations of human pathogenic viruses that exist in our daily environment, and 3) utilize a range of biomolecular and analytical chemistry tools to link virus particle characteristics to observed behaviors in natural and engineered environments. Our group also studies how drinking water and wastewater treatment processes can be modified to remove emerging chemical and biological contaminants.
