Research Theme: Questions that I focus on include: * What are the underlying controls over rates of carbon and nutrient cycling, and how do anthropogenic perturbations interact with these underlying controls? I am particularly interested in rates under anaerobic conditions and factors that control the emission of methane, a potent greenhouse gas, in wetlands. * Can ecosystems be restored to provide similar functions as natural ecosystems, and what is the role of plant community structure and succession in achieving successful restorations? * Climate change is a pervasive, on-going anthropogenic perturbation of natural ecosystems. How will it impact carbon and nutrient cycling, fire, and plant community structure in ecosystems as diverse as northern peatlands and prairies and oak savanna?
