My research program is focused on the plant root-soil interface.  My objective is to determine how roots and rhizosphere processes can be managed to improve efficiency of nutrient use, minimize environmental pollution, and maximize soil quality.  My present work includes the study of root-mediated mechanisms of enhanced nutrient acquisition and the effects of alternative cropping systems on soil quality and carbon and nitrogen dynamics.
