Andy MacDonald is a broadly trained ecologist who leverages field, lab and data driven approaches to understand how disease risk and transmission responds to global change. His research has focused on the effects of land use change and climate change on a variety of infectious diseases including Lyme disease and West Nile virus in North America, and malaria and dengue in the tropics. His research has also focused on the feedback between human health and conservation, identifying how environmental change can influence health, but also how health can influence natural resource use and conservation.
