Research InterestsMy research primarily centers on understanding the mechanisms and impacts of environmental change. I use an interdisciplinary approach and a variety of techniques to study past climate, vegetation assemblages, disturbance regimes, and human-environment interactions. Much of my work relies on the analysis of lake sediments. Lake sediments provide a window to the past that helps provide context for modern environmental changes and possible analogues for future conditions.
Much of my research has focused on Latin America. Using a sediment core from a lake in eastern Bolivia, I constructed a 5,000-year record of vegetation and climate change at the southern boundary of the Amazon forest. I have also worked in southwestern Costa Rica, where I used a network of five lake sediment cores to investigate sediment deposition processes and the effects of droughts on prehistoric agriculture. At Willamette, my students have used soil cores to examine prehistoric fire frequency and oak savannah/forest dynamics at Zena Forest. In the future, I plan to continue working with students to study past climate and vegetation in the Willamette Valley.
