Research Interests

I have been a member of the research department at the Holden Arboretum since 1992 and have provided technical expertise for all aspects of our research program, including field studies, greenhouse experiments, and laboratory and data analyses. I am interested in better understanding the relationships between plants and their environment and how changes, both local and global, impact plant evolution and survival. My current position provides lab management and primary support for the Medeiros Lab (plant physiology), investigating the evolution of functional traits in the genus Rhododendron, and the Wei Lab (evolutionary ecology), examining evolutionary relationships between plant species and the influences of the microbiomes associated with their roots, leaves and flowers.
