My research interests focus on understanding the effects of forest management practices and land-use history on forest biodiversity and ecosystem processes. I have quantified the relationship between disturbance regimes and northern hardwood forest structural heterogeneity (e.g., decaying logs, snags, decadent trees, root throws), and my colleagues and I are determining how these structural features influence the composition of vascular plant, bryophyte, lichen, amphibian and invertebrate communities. This research is being applied to develop forest management guidelines that will more effectively maintain biodiversity while permitting the sustained yield of forest products.

Additionally, I am investigating the capacity of native forest herb communities to reassemble in seral forests that have established after agricultural abandonment and am developing a regional citizen science program to actively restore native woodland herb communities to post-agricultural woodlands.

Finally, I am collaborating with ESF colleagues to develop new, integrated approaches for instructing introductory chemistry, biology and communications.
