J. Adam Langley, PhD
Department of Biology
Villanova University College of Liberal Arts and Sciences
Area of Expertise:
- Global Change Ecology
- Carbon Cycling
- Coastal Wetland Sustainability
Dr. Langley is the source to turn to for expertise on how ecosystems respond to, and may play a part in, global and environmental change. The future of ecosystems is extremely complex and uncertain, but Dr. Langley is working to predict changes through novel isotopic and gas exchange techniques that measure carbon and nutrient cycling. He has also done extensive research on the marshes in the Chesapeake Bay and can comment on the sustainability of coastal wetlands.
