Senior Lecturer in Plant Biology
Ph.D. 1991, University of Vermont
Office: 308 Jeffords Hall
Research Area: Plant Systematics and Evolution
Courses Taught: Morphology & Evolution of Vascular Plants (PBIO 108); Exploring Biology (BCOR 12); Systematics & Phylogeny (PBIO 109); Field Botany for Natural Resources Professionals (PBIO 381); The Green World (PBIO 6); Biology of Ferns (PBIO 209)
At present, I teach introductory biology to students in the Integrated Biology program. I also teach a diversity of courses in field botany, plant systematics, and plant evolution. A favorite is Field Botany for Natural Resource Professionals (co-taught with Elizabeth Thompson, community ecologist), a fast-paced field course designed to acquaint students with the diversity of vascular plant species in the Vermont landscape. It also emphasizes the organization of those species into natural communities and explores the important ecological determinants of plant distribution.

|Adiantum aleuticum (Aleutian Maidenhair Fern)|
As a member of the Plant Systematics Group at UVM, I am investigating the phylogeography of a set of plant species that are rare around Vermont’s Lake Champlain but which are common on sand dunes of the Atlantic Coast. We are currently finishing work on the taxonomy and biogeography of the Champlain beachgrass, Ammophila breviligulata subsp. champlainensis and on the migrational history of beachpea, Lathyrus japonicus. A parallel investigation of golden heather, Hudsonia tomentosa, is in progress in our lab. My own dissertation research was a study of genetic divergence and speciation in the Adiantum pedatum (maidenhair ferns) complex and of the role of geographic and ecological isolating mechanisms in promoting divergence and speciation within it.
