Research Interests

My research focuses on plant anatomical and physiological acclimation and adaptations to the abiotic environment. I am interested in how phenotypic and genetic variation in plant form and function interact with variation in climate over space and time to drive ecological patterns and the evolution of plant diversity. I focus primarily on plant hydraulic traits, including xylem water transport, leaf gas exchange and the integration of leaf and xylem function.  More information concerning my research interests and current projects can be found here.
