I am a community ecologist with a broad background in the ecology and conservation of terrestrial ecosystems. I take an empirical approach to my research, using experimentation and statistical modeling to answer both applied and theoretical questions about the dynamics and management of large herbivore-dominated systems. I am very lucky to have had the chance to work in some of the world’s most spectacular landscapes and am passionate about conserving wildlife in a world increasingly impacted by people.
As a newcomer to the Greater Yellowstone Ecosystem, I am working to develop a variety of research projects with the common theme of understanding how changes in land use (particularly, increased development) and climate may be impacting native biodiversity. Ultimately, I aim to increase our understanding of complex human-nature systems and how to better mitigate anthropogenic impacts on the functioning and diversity of one of the most intact ecosystems in the world.
I am also continuing some of my research on livestock-wildlife co-existence in the private conservation lands of Laikipia, Kenya, where I have been working since 2004. I am a co-PI on the NSF-funded Kenya Long-term Exclusion Experiment, a 17-year experimental manipulation of cattle and wild ungulates, in which I am asking questions about the long-term impacts of cattle and native herbivores on savanna dynamics and functioning. Other areas of my research include restoration of degraded grazing lands and understanding how an invasive ant species may have catastrophic ecosystem consequences by disrupting a native acacia-ant mutualism.
In addition to research, I am also committed to outreach and education. In 2010 I led a team of scientists, pastoralist land managers, and NGO workers to produce a guidebook and set of tools for quick and easy monitoring of East African rangelands. Since then I have held numerous training workshops and seen these monitoring methods adopted over large parts of sub-Saharan Africa. I have also taught a variety of more conventional field and classroom courses for undergraduates and graduate students, and mentored a diversity of students from the USA and Kenya. I thoroughly enjoy working with conservation practitioners and students and seeing scientific research guide management and create educational opportunities.
