My research is interdisciplinary. I use lake sediments (paleo data) to study past fires, vegetation, and climate changes to understand their interactions -- with each other and with human activities. I also study science communication and risk perceptions, particularly as they relate to weather and climate.

My fire research focuses on documenting and explaining where, when and why fires occur -- in the western U.S., in eastern North America, on other continents, and at the global scale -- with lots of help from the paleofire community. Fire fascinates me because it interacts with so many other things -- weather and climate changes, vegetation, topography, landscape structure, and human activities, like logging, grazing, agriculture, etc. Fires and their emissions (which include both carbon dioxide and methane) show large variations across both space and time. I take a long-term view of fire and am particularly interested in what happens to fires when there are very large, broad-scale climate or land-use changes, because these changes have major implications for economies, livelihoods, ecosystems, air pollution, and climate change.

I also study science communication and risk perceptions, primarily through the analysis of public opinion survey data. I conducted a study of Connecticut coastal residents hurricane risk perceptions, for example, and worked on a large mapping project to identify Americans' opinions about climate change at state, congressional district, and county levels. It is critical to understand risk perceptions because these are what motivate our decisions and actions when we are faced with a threat, whether real or perceived.
