Members of my research group use a combination of ecology, economics, and policy research to find innovative ways to protect biodiversity around the world. Recent or ongoing projects include: conservation of migratory animals in North America and Asia; impacts of hunting and the wildlife trade on biodiversity; effects of land-use change and climate change on biodiversity in East Asia, Southeast Asia, and the Amazon; conservation of coral reefs; and nature-based climate solutions. Although many people in my research group have studied birds, we study all sorts of plants and animals, including reptiles, mammals, fish, dung beetles, and butterflies (but nothing too small to be seen with the naked eye). Prior to joining the Princeton faculty in 2001, I served as senior ecologist with the Environmental Defense Fund (1991-2001) and The Wilderness Society (1986-1991). I am an avid birdwatcher who has shamelessly used his students' and postdocs' research projects as a justification to chase rare birds from Brazil to Brunei and from China to Costa Rica.
