Courses:   Ecology and Evolution (BIO 124), Forest Ecology (BIO 427).


Research Interests:  Forest restoration ecology in tropical and temperate regions, tree seedling response to environmental factors and site treatments.

My research interest in forest ecology currently focuses on seedling regeneration ecology, succession, and restoration of native forests in Virginia and West Virginia.  I investigate the processes affecting the regeneration of natural forests and the reintroduction of economically important, native tree (American chestnut) and herbaceous species (American ginseng).  I use experimental treatments to identify optimal locations for reintroduction of these species.   My basic applied research objective is the identification of management techniques for enhancing forest ecological integrity, maintaining forest diversity and ecosystem services.
