Professional Interests - Plant resistance to insects, Plant signaling mechanisms, Induced defenses, Insect effectors

Professional Responsibilities
Research:
The Molecular Plant-Insect Interactions Lab’s research focus is on identifying the key components/genes/signaling mechanisms that are involved in modulating plant defenses upon insect herbivory and to understand the mechanisms by which insect salivary proteins/effectors alter the plant defense responses.
Teaching:
ENTO 409/809, Insect Control by Host Plant Resistance
ENTO 835, Chemical Ecology of Insect-Plant Interactions
