RESEARCH THEMES

Scientific expertise

  • Genetics and Tree Improvement
  • Forest genomics
  • Forest biotechnology
  • Wood chemistry

I occupy a position as an assistant professor in tree genomics at Université Laval and the Département des sciences du bois et de la forêt, Faculté de foresterie, de géographie et de géomatique. My long-term research program is related to the elucidation of the genetic underpinnings of wood quality traits in the context of tree improvement with a wider focus on wood component valorization. I also perform research on understanding and improving biotic and abiotic stress resilience in forest tree species. Based on my training as a biochemist, I have a broad interest in genomics and in various organisms and therefore I have recently started to investigate the genetic basis of invasiveness attributes of several serious alien forest pests in Canada. Related to my research in forest genomics, I have profound interest to help support the economic potential of forest genomics in Canada. I am looking forward to the many fruitful collaborations with my colleagues at the CEF.
