Heather is responsible for managing the stable isotope program at the Savannah River Ecology Laboratory. Her research interests include the general areas of inorganic toxicology, crayfish ecology, avian ecology, and stable isotopes as applied to the understanding of ecosystems. Her recent research has included dynamics of mercury, and other metals, within aquatic habitats and the chronic, sub-lethal effects on associated organisms.
