Research Summary:

My research program is focused on plant defenses against herbivory, with an emphasis on mechanisms of resistance against vascular feeders such as aphids and root-knot nematodes. Vascular feeders can cause massive physiological changes in their host plant such as galling, and many of these herbivores are also important vectors of plant pathogens. Their interactions with plants are therefore important from both an ecological and a practical agricultural perspective. Despite this, relatively little is known about the physiological or molecular basis of plant responses to vascular herbivory. I am using tomato (Solanum lycopersicum) and Arabidopsis thaliana as model systems to investigate this question, and to explore the relationship of plant defensive pathways induced by aphids and nematodes to plant defenses against other biotic and abiotic stresses. My laboratory studies both broad-spectrum, induced defenses against herbivores and isolate-specific, resistance-gene-mediated innate resistance, and utilizes molecular and genomic approaches to identify potential sources of resistance against insects.
