Overview
My research focuses on understanding the causes and consequences of patterns of biological diversity across the planet. I am particularly interested in two broad questions: 1)How does the modification of the environment by organisms affect community structure and ecosystem function? and 2) what aspects of biodiversity matter most in the regulation of ecosystem function? While much of my research has focused on wetland plant communities, I am willing to study any organism and work in any ecosystem to answer the questions that interest me. I have worked in systems ranging from tropical streams to desert shrublands. My research program combines observational and experimental approaches with modeling to develop and test hypotheses and build towards synthetic ecological theory.

Surface Elevation Trends in Natural and Restored Coastal Forested Wetlands Reveal Vulnerability to Saltwater Intrusion and Sea Level Rise
Journal article Estuaries and Coasts · March 1, 2026 Accelerating sea level rise and increasing frequency of storms are impacting coastal wetlands. Similar to salt marshes, coastal freshwater wetlands provide important flood protection and storm abatement services, but their capacity to keep up with sea leve ...
