I am an Assistant Professor in the Environmental Studies Department at Wofford College. My research interests include tropical ecology, conservation biology, and sustainability in human-modified ecosystems. My current field sites are located in the Brazilian Atlantic Forest, Pantanal, and Cerrado biomes, where I use large mammal habitat use patterns as conservation proxies for evaluating changing tropical ecosystems.

Tropical ecosystems regulate global climate, act as carbon sinks, and contain some of the highest levels of biodiversity in the world. Yet, they are also among the most threatened ecosystems on the planet. Thus, knowledge of their evolution and response to changing conditions is of critical importance.
Large mammals provide an interesting angle through which to evaluate changing tropical ecosystems, as they have unique top-down effects and can directly moderate ecosystem services, species diversity and abundance, and amount of suitable habitat for other organisms. My research combines techniques from conservation biology, computer modeling, landscape ecology, stable isotope geochemistry, and movement ecology to understand how large mammals access and utilize their environments and how aspects of their biology, including diet and movement, vary in fragmented and agricultural ecosystems. Analyzing these large mammal habitat use patterns provides information on how ecosystems may be altered in the future in response to anthropogenic alteration.
