Molecular Insect Biology
Current research and/or projects
Insects are thoroughly fascinating creatures and I knew from a young age that I would be studying them eventually. After completing my undergraduate studies in biology at Laval University, I crossed the street over to the Laurentian Forestry Centre lab to work on my master’s degree, to study the physiological interactions between the spruce budworm and one of the numerous species of parasitic wasp attacking it. As modern molecular biology was taking off in the 1990s, I decided to pursue doctoral studies on the molecular mechanisms of cold hardiness in spruce budworm, and then completed a postdoc in the genetics of immunity in fruit flies. My interests cover a broad range of topics on forest pest insects, with the common theme of using molecular knowledge to understand adaptation and physiological processes that have practical implications in forest pest insect management. Two relevant examples include cold hardiness in budworm and olfaction in forest pest beetles.
