Welcome to the Aquatic Ecology and Environmental Change Lab!

The Sweetman lab is part of the Department of Ecosystem Science and Management at Penn State University in State College, Pennsylvania.  Research in our lab is focused on understanding the potential impacts of the cumulative effects of climate change, population growth and land use change on freshwater lakes and wetlands.  

Research in the lab is often multidisciplinary and collaborative.  Several approaches are used, including the use of paleolimnology – looking at archives in lake sediments, along with large-scale surveys and experimental approaches to examine the consequences of environmental changes to aquatic ecosystems.
