"My research broadly examines the impact of global capital on development and on the well-being of both human populations and the ecosystems that sustain them. Specifically, my research looks both at the level of larger processes on the historical development of capital, and at the local variants of capital it has spawn. In pursuing these interests, I have focused on credit: looking at how it is culturally embedded and used as economic instrument, social relationship, and technology of power. At the level of local processes, my research examines the incorporation of local populations and local ecologies into wider systems, and how their inclusion in them changes their dynamics."
Her main research interests include climate impacts, vulnerability and adaptation, and climate policy and mitigation especially in the developing world. She also works on the political economy and political ecology of environmental management in the Americas, especially in Mexico.
