I am a wildlife ecologist with broad interests in conservation, population biology and animal behaviour. I graduated in Biology from Duke University (2002), and completed a PhD in Ecology and Evolutionary Biology at Dartmouth College (2011). I have conducted research in East Africa for 20+ years. In Glasgow, I direct the Conservation Management of Africa Ecosystems MSc programme.
ORCID ID: 0000-0001-7262-1402
Research interests
My research aims to understand how and why animals move, and what the consequences are for those movements on population dyanmics, species interactions and disease. Often, the work is motivated by questions posed by ecosystem managers and conservationist practitioners. I lead projects on animal movement and parasite infection in Tanzania and the U.K., in collaboration with veterinarians and parasitologists.
