Research & Teaching Interests:
I enjoy teaching botany, general biology, cell biology, plant physiology, evolution, and plant development.
Scholarly Activities:
The movement of plants from the water to the land created the need for plants to become larger and erect in order to compete for light. This transition resulted in the evolution of vascular tissue, stomata, guard cells, and the cuticle. My research examines these features across the extant plants to begin to fill in the evolutionary relationships between the physical changes and the physiological processes.
I am also currently working with the National Park Service, helping classify which basal land plants are in the parks.
