Sally Horn’s research interests are global environmental change and human-environment interactions during the Quaternary period of Earth’s history, which began some 2.6 million years ago and includes the “Ice Ages” of the Pleistocene as well as the warmer Holocene epoch in which we live today. She has conducted research on the impacts of Quaternary climate change and prehistoric and modern human activity on vegetation and landscapes of the Southeastern U.S., Central and South America, and the Caribbean and tropical Atlantic regions. The work that she and her collaborators and students have done has brought issues of past global change to the forefront of discussions of 1) the modern dynamics of tropical forests and other tropical vegetation, 2) human settlement and subsistence patterns, and 3) strategies for management of national parks and wildlands.

Horn currently directs the University of Tennessee’s Initiative for Quaternary Paleoclimate Research, also linked above.
