As a plant evolutionary ecophysiologist, I am principally interested in how key plant traits mediate adaptation to diverse environmental pressures. These include abiotic factors like climate and soil fertility, and biotic factors like herbivory and disease. All plants face physiological trade-offs between growth, defense, and reproduction, and I seek to understand the coordinated evolution of the traits that govern these three core functions.
Two major classes of traits that govern plant growth rate and the tolerance of biotic and abiotic stresses are leaf economic traits and leaf defenses. As a Putnam Fellow, I am studying the evolution of leaf physical and chemical defenses in relation to the leaf economics spectrum, leaf habit, and species’ source latitude and climate across 16 woody genera well-represented in the living collections of the Arnold Arboretum. As a huge common garden of thousands of species of temperate trees and shrubs, the Arboretum provides one of only a handful of locations worldwide in which this broad phylogenetic comparative work is possible.
