Research interests

My research examines plant-insect interactions at the level of the individual organism, focusing on behaviour, nutrition and chemical ecology.

I investigate questions about the roles of social relationships with conspecifics and of trophic relationships with food plants and natural enemies. My focus is on outbreaking pest insects, both in Canada (Forest Tent Caterpillar and Spruce Budworm) and internationally (desert locust), and in biodiversity conservation in the Montreal urban landscape and in the neotropics.
