I am interested in a diversity of topics in population and ecological genetics within the broad context evolutionary ecology. My research is question-driven and has included both animals and plants. Over the past several years my research has focused on the effects of inbreeding on the interactions between plants and their antagonists (herbivores and pathogens) and their mutualists (pollinators). In addressing these problems I have conducted experiments in the field as well as the greenhouse, and my approach has relied extensively on the techniques of quantitative genetics. A second focal area of research has been the ecology and genetics of non-native invasive plant species.
