CURRENT & FUTURE RESEARCH:  Biology and ecology of Alliaria petiolata, Lonicera Maackii, Paulownia tomentosa, and Ailanthus altissima.  

PAST RESEARCH:  1. Response of a forest understory community to experimental removal of an invasive non-idigenous plant (Alliaria petiolata, Brassicaceae).   2. An assessment of the allelopathic potential of the invasive weed Alliaria petiolata (Brassicaecae). 3.Competitive ability of Alliaria petiolata (garlic mustard, Brassicaceae), an invasive, non-indigenous forest herb.  4. Responses of the biennial forest herb, Alliaria petiolata, to variation in population density, nutrient addition, and light availablity.  5. Genetic variation and molecular biogeography of a North American invasive plant species (Alliaria petiolata, Brassicaceae).  6. Effect of environmental variation on the invasive success of a non-indigenous forest herb.   7. Biomass allocation and resprouting ability of princess tree (Paulownia tomentosa: Scrophulariaceae) across a light gradient.   8. Effect of density on the demography of an invasive plant (Alliaria petiolata, Brassicaceae) population in a southeastern Ohio forest.    9. Seed and seedling ecology of Paulownia tomentosa, a non-indigenous tree species in the central Appalachians.
