My current research efforts are in the arctic tundra of Alaska and Canada, the grass-shrub ecosystems of the Chihuahuan Desert, and successional fields of northern Virginia. In the Arctic, we are examining the dynamics of tundra vegetation in response to climate change and interactions among tundra vegetation, nitrogen cycling and freeze-thaw disturbances. In the Chihuahuan Desert of New Mexico, we are studying the interactions between vegetation structure and wind erosion of soils. In the Virginia Piedmont, our research focus is on vegetation dynamics and carbon sequestration as land succeeds from managed regimes to secondary forest.
