Born and raised in Wilhelmshaven, Germany, Dr. Mario Bretfeld studied Landscape Ecology at the Carl-von-Ossietzky University of Oldenburg. During an exchange year in Colorado, he studied aspen (Populus tremuloides) regeneration in response to different disturbances, including fire and conifer mortality due to mountain pine beetles. After graduating in 2010, he returned to Colorado to pursue a Ph.D. at the University of Northern Colorado in the Franklin lab. His dissertation research included long-term aspen community changes in and around Rocky Mountain National Park, responses to the mountain pine beetle outbreak, and resource sharing through the connected root system of aspen (i.e. clonal integration). He received his Ph.D. in Biological Education in 2014.

After graduation, Dr. Bretfeld moved to Panama as part of a post-doctoral fellowship with the Smithsonian Tropical Research Institute (STRI) and the University of Wyoming. In Panama, he worked primarily in the Agua Salud project and measured plant water use (i.e. transpiration) in regrowing tropical forests of different ages, as well as in a cattle-pasture and a coffee plantation. From April 2017 to July 2019, he lived and worked in Laramie as a post-doctoral fellow in the Ewers lab at the University of Wyoming. Since August 2019, he has served as assistant professor of biology in the Department of Ecology, Evolution, and Organismal Biology at Kennesaw State University.
