My research interest is in conservation biology and how we can use math and modeling to make better decisions regarding conservation. While studying my master’s degree I used bog turtles (Glyptemys muhlenbergii) as a case study for how we can resource-efficiently locate and survey rare and elusive species. This work combined species distribution modeling and intensive field work in close collaboration with state wildlife agencies in the United States to give me first-hand experience into what it means to conserve species at ground-level. For my Ph. D. I am changing my focus to examine how movement affects population dynamics in highly mobile animals. My study system is the Eastern Steppe of Mongolia and the nomadic Mongolian Gazelles (Procapra gutturosa). I will simulate this system by programming an herbivore-vegetation model. To do this I am combining expertise from the two working groups I am involved in. I am a part of Thomas Müller’s group, whose focus is on movement ecology and conservation, and Thomas Hickler’s group, whose focus is on vegetation modeling and effects of climate change. We hope this modeling approach will help us better understand how important mobility is to long-term population persistence of animals living in unpredictable and dynamic landscapes.

My work is part of the BMBF project MoreStep which brings together social and ecological sciences to identify societal drivers that can lead to an ecological tipping point of the Mongolian steppe ecosystem. Our role is to use the herbivore-vegetation model to examine the importance of movement in maintaining sustainable numbers of wild and domestic herbivores. The model will also be used to disentangle the effects of climate and grazing on vegetation.
