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.

Journal Article Journal of Ecology · January 1, 2025 Disturbances can have enduring impacts on ecological communities due to ‘legacy effects’, which result in community structure that varies with the history of recent disturbance. Further, such legacy effects can influence community—and population-level resp ...

Journal Article Forests · September 1, 2024 Salt-sensitive trees in coastal wetlands are dying as forests transition to marsh and open water at a rapid pace. Forested wetlands are experiencing repeated saltwater exposure due to the frequency and severity of climatic events, sea-level rise, and human ...

Journal Article Anthropocene · March 1, 2024 The United States (U.S.) coastal plain is subject to rising sea levels, land subsidence, more severe coastal storms, and more intense droughts. These changes lead to inputs of marine salts into freshwater-dependent coastal systems, creating saltwater intru ... Full text CiteRecent Grants
