Over the past 20 years I have conducted research in a variety of topics across temperate, boreal, maritime and polar settings. Primary areas of interest include the influence of disturbance on N and C cycling in prairie, forest, and tundra ecosystems, fire ecology, biological N2 fixation, invasion ecology, and restoration ecology. Ongoing research projects include a Swedish Riksbank funded project on land use history and ecosystem function in boreal and tundra ecosystems of northern Sweden and three separate UK based National Environmental Research Council grants on N cycling in boreal forest ecosystems, N cycling in Antarctic ecosystems, and macronutrient cycling in a large river catchment in Wales.
