Ecology of forest herbs and vines; Ecology of Canada yew; Ethnobotany of the Potawatomie people.

Present projects include investigations to decrease growing time of native forest herbs by manipulating environmental conditions to achieve multiple cycles of growth and dormancy in one calendar year; investigation of optimal host diameter for twining vines needing to select small enough hosts to place them near to the well-lit forest canopy but not onto supports that are shed annually, such as the rachii of compound leaves or pedicels of simple leaves; and vegetative predictors of amphibian diversity in vernal pond breeding sites.
