Magna Cum Laude – The Affects of Papermill Waste on Deciduous and Alder Forest Soil Invertebrates.
University of Lancaster, UK
I am broadly interested in examining food web dynamics by investigating the foraging ecology of higher predators. Currently, my dissertation focuses on the transport and fate of organic contaminants in Antarctica, their incorporation into the Antarctic food web, particularly higher predators, and their use as tracers in seabirds breeding on the Antarctic peninsula.
July 2004 - Present
