My research in plant ecology and conservation has the following cross-cutting themes:

  1. Clonal growth as a mechanism for population persistence in plant communities
  2. Anthropogenic drivers of forest change
  3. Science conducted so as to inform land-use decision-making, public policy, and conservation efforts.

Recent Publications (*Undergraduate or lab alum co-author):


I direct the Sewanee Herbarium, which serves as a center for the study of plant biodiversity on the Cumberland Plateau. The Sewanee Herbarium has catalogued 1,120 species of vascular plants on Sewanee's 13,000 acre campus (Domain) as part of the Flora of the Domain project. The Herbarium sponsors undergraduate and post-baccalaureate fellowships.


I run Sewanee's Field Study in Belize Program which takes students to Belize to explore rainforest and coral reef ecology. Since 2011, this course has logged photos of over 500 species of animals and plants on the course iNaturalist site.  View the Field Study in Belize Slide Show!  I also work with Friends of Conservation and Development to promote rainforest conservation and provide student internship opportunities in Belize.  A recent intern was instrumental in helping me develop a web course module on deforestation in Belize, funded by the Associated Colleges of the South.
