My research program focuses on ecological and evolutionary processes mediating complex interactions between organisms and the environment. I am particularly interested in ecological interactions between plants and insect herbivores and their co-evolutionary adaptations. For example, plants have developed a wide array of defenses to withstand herbivore attack (e.g., secondary chemicals and structural barriers); likewise, herbivores have evolved offensive mechanisms, which allow them to utilize their plant hosts (e.g., feeding behavior and metabolic degradation of plant chemicals).
Using the model system Arabidopsis thaliana, I have evaluated plants responses to anthropogenic change (e.g., atmospheric CO2 enrichment) and to herbivory by insects differing in their degree of ecological specialization (generalist vs. specialist insects) or feeding habits (leaf miners vs. phloem feeders).
I am currently developing collaborative projects integrating evolutionary ecology, ecological genomics, chemical ecology and conservation ecology. These projects are aimed at better understanding how current anthropogenic environmental problems (global change, biological invasions, deforestation, etc) affect ecological interactions among species, evolutionary processes, the structure of communities and ecosystem functioning.
