Research Programs and Interests
My research program uses molecular, proteomic and physiological approaches to investigate insect-plant interactions. My main interests are investigating the counter measures herbivores use in overcoming host plant defenses. Particular interest is on the role of herbivore salivary signals in suppressing the induced defenses of host plants.
The role of saliva of blood feeding arthropods in suppressing the defenses of their vertebrate hosts has been comparatively well studied; however, very little is known about how the saliva of herbivores may interfere with plant defensive responses. Our projects focus primarily on the saliva of caterpillars. Recent findings indicate that saliva is enriched with an array of molecules that function in defense against microbial infection, digestion of plant tissues, and in suppressing induced defenses of plants. We employ a variety of surgical and genetic approaches (e.g., RNA interference) to examine function(s) of saliva.
