John is an applied ecologist who uses an integrated field and modeling approach to study the effects of climate change, in general, and rising sea-levels specifically, on coastal systems. He is especially interested in modeling the non-linear feedbacks that allow coastal wetlands to maintain a dynamic equilibrium with sea-level. He uses those models to predict the resiliency of estuarine systems to rising water levels and to guide the course of restoration and mitigation efforts. This work has led to recent efforts to quantify rates of carbon sequestration and calculate carbon budgets for coastal wetlands in the Pacific Northwest.
John holds a PhD in Oceanography from Louisiana State University, a MS in Ecosystem Biology from Eastern Michigan University and a BS in Wildlife Biology from Michigan State University.
