I’m broadly interested in plant structure and function, and the manner in which plants respond to climatic perturbation. I am especially interested in water transport and how plants balance the need to efficiently supply water to the leaves while maintaining appropriate resilience to drought stress. Critical to our understanding of plant response to both past, current and future climate change, this basic safety-efficiency tradeoff has shaped in large part, the evolution of plant form and function and it constrains the physiological thresholds that shape extant plant biogeography. My work combines field work with experimental studies, and includes extensive lab work and as well as detailed anatomical analyses of cell structure.
My current projects include:
1. the evolutionary ecophysiology of seedless vascular plants such as ferns and lycopods
2. the short- and long-term drought response of redwood understory vegetation
3. Cenozoic climate change, and how it shaped the evolution of vascular plants
4. the evolution of xylem, including xylem allometry in seedless vascular plants
5. the ultrastructural aspects of plant biomechanics
I encourage my students to explore their own interests within the broad context of plant ecophysiology.
