About John
My research has a strong focus on wetland biogeochemistry, and in particular the regulation and transport of carbon in wetlands. I study wetland ecosystems in coastal, low elevation inland, and mountain environments in diverse climates across temperate and tropical regions. Because wetlands around the globe can serve as a large long-term carbon sink, but when perturbed can become sources of greenhouse gases, an improved understanding of wetland processes is critical from both a fundamental and applied perspective. I am particularly interested in understanding the impacts of shifting land use and a changing climate on wetlands, and how we can apply management and restoration strategies to mitigate the negative effects of these stressors within a local and global context.
