I work with researchers at Oregon State University and other institutions (e.g., USGS, PNNL, NOAA NERR system) to study climate change impacts to west coast estuarine wetlands, carbon storage in coastal wetlands, and ecosystem responses to tidal marsh restoration. Along with collaborators, I use experimental, observational, and modeling approaches in my research including greenhouse and field experiments. I have active field sites in California, Oregon and Washington, a region which incorporates a gradient in coastal climate conditions for estuarine wetlands. Some of my field research and monitoring includes channel and groundwater hydrology monitoring, manipulative experiments to study inundation and salinity effects on plant productivity, and measurement of organic matter decomposition rates. In the greenhouse and laboratory I conduct work on plant germination, productivity, and fecundity.

My research focuses on the structure, function, and vulnerability of tidal wetland plant communities along the Pacific coast of the US. I have three major projects: (1) Understanding how climate change impacts wetland plant community structure and ecosystem functions such as decomposition and productivity, (2) Assessing blue carbon stocks in Pacific Northwest estuaries, and (3) Evaluating ecosystem responses to tidal wetland restoration. I use a variety of approaches to address these questions including manipulative experiments. My other academic interests include phycology, plant biogeography, and estuarine hydrology.
