Current Research

My primary personal research focus is NED, a set of decision-support tools for forest management for multiple benefits. Other research interests include biotic disturbances in forests, regeneration dynamics, stand development, and the roles of humans in the ecosystem.
I have active studies examining the effects of various silvicultural practices on several different components of the forest, including the trees, vascular flora, deer browsing, and salamanders.
I am participating in several studies of beech bark disease, focusing on its effects on the composition and structure of the residual forest.
I have ongoing work addressing public participation in forest planning activities.
I am active in working with educators to develop environmental literacy components to public school curricula. I have collaborative studies working with managers of reservoirs and city parks to develop forest management plans for their properties.

Research Interests

Develop integrated decision-support systems for forest management for multiple benefits.
Investigate relative effects of different silvicultural systems for a variety of forest benefits.
Provide tools for urban forest managers to evaluate alternative management activities on their forested properties

Education

Yale University, School of Forestry & Environmental Studies, Ph.D. Silviculture, 1987

Moving Field Guides: Learning ecology through dance

Year: 2011

Children in Baltimore, MD, are working with Forest Service researchers and the Dance Exchange, a professional dance company, to turn their observations into movements as they learn about the environment. The result, a Moving Field Guide, is a dance representing natural events, such as bark sloughing off a tree and ducks migrating, that links students to their local environments in personal and enduring ways.
