Christiane Runyan

During the summer of 2006, Christiane completed a two-month research trip to Africa, traveling through South Africa, Zimbabwe, Zambia, Botswana, Namibia, and Tanzania.

In 2008, Christiane obtained an M.S. in Environmental Science and Policy from Johns Hopkins University. She is currently working on her PhD at the University of Virginia. Christiane's research focuses on how deforestation affects the dynamics of hydrological and biogeochemical processes. When vegetation controls the physical and biogeochemical conditions in a way that makes it more suitable for their persistence, deforestation alters the conditions necessary for forest regeneration. For systems that exhibit these dynamics, changes in land use can cause an abrupt and highly irreversible shift from a fully vegetated state to a bare state with limited vegetation. Understanding these system dynamics is useful for developing sustainable management plans that can be used to conserve forests.
