Research questions in my lab focus broadly on biogeochemical interactions between microbes and their chemical environment, and how these exchanges affect ecosystem functioning. As an ecosystem biogeochemist, I am interested in the complex interactions and feedbacks between biogeochemical transformations and ecosystem function, especially in an era where humans have made a large footprint across the globe. Using interdisciplinary, multi-scale approaches, we seek an integrated understanding of the biogeochemical controls on (1) climate change induced, sea-level rise on C, N and P cycling in freshwater tidal wetlands of the Delaware Estuary, (2) carbon accumulation and decomposition dynamics in northern boreal, western Canadian peatlands under future predicted scenarios of global climate change, (3) the effects of anthropogenic disturbances (e.g., oil sands mining pollution and increased fire intervals) on nutrient cycles in peatlands in Alberta and most recently, (5) the role of nitrogen fixation in bogs and fens in both pristine and compromised parts of the world.
