Senior Research Scientist Emeritus, Arnold Arboretum
Visiting Lecturer of Applied Ecology and Planning, MIT
My research interests are wide ranging and mainly involve the interaction between woody plants and their environment. Over the course of thirty plus years at the Arnold Arboretum, I have worked with a number of plants, most notably Ginkgo biloba, conifers in the genera Tsuga and Sequoia, various magnolias, and several Stewartia species (family Theaceae). In all of my work, I attempt to integrate various aspects of the botany and ecology of a given species with the horticultural issues surrounding its propagation and cultivation. This fusion of science and practice has also formed the basis of my teaching at the Harvard Graduate School of Design (since 1992), especially as it relates to understanding the impacts of climate change and urbanization on plants in both native and designed landscapes. Most recently, the focus of my research has expanded to the subject of spontaneous urban vegetation which resulted in the publication of “Wild Urban Plants of the Northeast: A Field Guide” (Cornell University Press, 2010).
