Current Research

I am interested in ecosystem and community level responses of southern forests to management practices such as prescribed fire and mechanical thinning. I am particularly interested in how carbon and nitrogen dynamics are affected by these practices. Also of interest are the responses of invertebrate communities (e.g. earthworms, herbivorous insects, etc.) these land management practices, and how changes in invertebrate assemblages may lead to changes in other components of forest systems (e.g. nutrient relationships, plant-herbivore relationships).
