Current Research

I am interested in soil ecosystem responses to natural disturbances (fire, wind, and flood), forest management practices which seek to simulate disturbances (prescribed fire, thinning, harvesting), and anthropogenic disturbances (e.g. invasive species).  I am particularly interested in responses of soil biota (e.g. earthworms, herbivorous insects, soil microbes, etc.) to these disturbances and 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).  In addition to pure soil biology, I am also interested in elemental dynamics, and specifically the effects of prescribed fire on soil organic matter and toxics (soil carbon, nitrogen, and mercury).
