grogan2.JPG Research: I am an ecologist who is particularly interested in evaluating the physical, chemical and biological controls that regulate biogeochemical cycling in terrestrial ecosystems. Biogeochemistry addresses the links between biology and the flows of energy and nutrients on Earth, and so provides a central foundation on which to explore many questions in ecosystem ecology. My research questions tend to focus on plant-soil-microbial interactions that affect patterns and controls over carbon and nutrient cycling, and can link across organism, community and ecosystem levels within terrestrial ecology. I have conducted studies in arctic tundra, boreal forest, mediterranean pine forest, annual grassland and abandoned pasture ecosystems.
