Through my research I seek to expand our knowledge of organic matter processing and biogeochemical cycles in ecosystems. I am particularly interested in the role of fungal organisms in these processes. Despite the wealth of qualitative evidence indicating fungal colonization of plant detritus, very little research has examined the quantitative impacts of fungal organisms on biogeochemical cycles at the ecosystem scale, or their potential contribution to total ecosystem metabolism. The main area of my research focuses on fungal-mediated detrital processes in freshwater and estuarine ecosystems, specifically emergent marshes. However, over the years my interests have expanded to include a variety of research questions ranging from microbial interactions in ecosystems to other potential impacts (e.g., oil spills, invasive species) on fungal-mediated detrital processes.
