Plant Physiology, Ecology and Evolution
Our lab at Holden Arboretum focuses on understanding the complex relationships between plants and their environment, and the evolution of plant physiological adaptations.
We employ techniques from eco-physiology and evolutionary ecology to investigate:

Network Mission:
The Rhododendron Research Network is a collaborative working group that enhances participation, value and dissemination of scientific discoveries in Rhododendron.
Network Goals:
1. Promote Rhododendron as a study system in plant physiology, pathology, ecology, evolutionary biology, plant breeding, genetics, horticultural sciences, conservation biology, ethnobotany, and medicinal chemistry.
2. Promote the ARS and associated botanical gardens as a resource for Rhododendron research and public engagement, and foster participation and membership of scientists in the American Rhododendron Society.
3. Create opportunities for communication and collaboration within the international community of Rhododendron researchers, and between scientists and ARS members.
