I study plant population and community ecology, primarily in temperate and tropical forests. I have ongoing projects examining invasive plant ecology and phylogeography, tropical forest succession, global liana ecology, rare plant dynamics, and rainforest dynamics on the Caribbean island of Dominica.
My research uses ecological and molecular genetic techniques to address a number of ecological questions: What are the ecological and evolutionary processes that affect and maintain genetic variation and structure in plant populations? Which current and historical factors determine the diversity and composition of plant communities? What are the roles of herbivores and pathogens in determining plant abundance and distribution on local and broad geographic scales?
