Research in this area is focused on mechanistic and process-level studies designed to provide a fundamental understanding of theoretical and applied problems in earth science. The research typically involves Quaternary geology, geomorphology, hydrology, and ecosystem ecology and is closely linked to research programs in marine and terrestrial biogeochemistry. Many of our programs have a tropical component and all research products are useful for management, restoration and remediation of ecosystems.
Students seeking a PhD in this area should contact individual faculty members and apply to the Graduate Group in Earth and Environmental Science. Students seeking professional Masters degrees should apply to the Masters of Environmental Studies or the Masters of Science in Applied Geoscience.
Ongoing research involves instream flow and water-allocation problems and studies on the impacts on and recovery of ecosystems after natural and anthropogenic disturbances including, whole-tree harvests, landslides, hurricanes, and chronic air-pollution and coral bleaching events. Another major focus is theoretical and experimental research on sediment transport and landscape evolution at a variety of scales. Much of the research is done in collaboration with the Luquillo Long-Term Ecological Research site in Northeastern Puerto Rico and the Luquillo Biocomplexity Project. Other on-going projects include assessments of relationships between river and road networks on aquatic resources, assessments of the effects of reservoir building on Mayan archeological sites in Central America, instream-flow and water allocation issues on Caribbean islands, water quality trading in Pennsylvania, wetland reconstruction in Iraq, developing geophysical techniques to locate buried drums of toxic materials, detailed aquifer studies of EPA Superfund Sites in southeastern Pennsylvania and geoarcheology of prehistoric sites in eastern North Africa.
