RechercheMon programme de recherche est intégrateur et combine la biologie moléculaire, la physiologie, la génomique, la transcriptomique, la protéomique et la biologie évolutive afin de tenter de répondre aux questions suivantes : comment se forment les nouvelles espèces? Comment les organismes s'adaptent à leur environnement? Mon équipe s’intéresse particulièrement au rôle des mitochondries et de leur génome dans les processus d’adaptation et de spéciation. Mes recherches s’efforcent donc de mieux comprendre la fonction, la structure, l’expression, l’évolution et la transmission des génomes mitochondriaux, la coadaptation des génomes mitochondriaux et nucléaires et les mécanismes physiologiques d’adaptation des animaux aux contraintes environnementales.Prix et honneursMédaille d'or académique du Gouverneur Général du Canada, 2003 Étudiants CSBQAlizée DebelliM.Sc.
