B.S. 1993, Lake Erie College


Research Interests


I have been a member of the research department at The Holden Arboretum since 1992, and provide technical expertise for all aspects of our research program, including field studies, greenhouse experiments, and laboratory and data analyses. I work closely with Holden scientists to design and plan experimental objectives and coordinate their implementation. My current research project areas include: investigating the evolution of functional traits in the genus Rhododendron, and examining changes in herbaceous and forest communities as a result of biotic and abiotic changes in the environment.
