My research interests are focused in two general areas: 1)  impacts of forest management on soil properties and long- term site productivity and 2) utilization of forests and trees in waste recycling and site remediation. I teach a variety of courses ranging from a general course on the natural history of Georgia to courses on waste recycling to forests. I have strong interests in international programs and have been a leader developing programs with Brazilian colleagues.

International Experience:

Advisor to graduate students from Austria, Brazil, China, Great Britain, New Zealand, The Philippines and Sri Lanka; Developed two FISPE-funded undergraduate exchange programs (with N. Comerford) between UGA and UF and several Brazilian universities; part of a team awarded a grant, to help communities in the Amazon develop food and energy production alternatives, Fulbright Visiting Scholar, Federal University of Rio Grande do Sul (2014).
