Maikel Rosabal

Professeur agrégé, département des sciences biologiques, Université du Québec à Montréal (UQAM)
Diplomé à l’Universidad de La Havana en biochimie avec intérêt pour la recherche en écotoxicologie, j’ai débuté un projet de maîtrise à l’INRS sous la supervision de Landis Hare et Peter Campbell en 2009. Ensuite, j’ai décidé d’entamer un projet de recherche doctoral avec la même équipe. Mes recherches portaient sur la gestion intracellulaire de plusieurs métaux dans deux modèles d’animal : larves d’insecte et des anguilles. Les résultats de recherche générés dans ces études m’ont permis d’obtenir la médaille d’or du Gouverneur Général de Canada. J’ai fait une année de recherche postdoctorale dans le laboratoire de Marc Amyot (Université de Montréal) en 2015 et une année après, j'ai été engagé comme professeur au département des sciences biologiques à l’Université du Québec à Montréal. Les recherches de mon équipe portant d'abord sur la compréhension de la manière dont les métaux traces provoquent des effets délétères en interagissant avec des biomolécules importantes au niveau subcellulaire dans différents tissus d'organismes aquatiques, ainsi que sur l'évaluation des conséquences biochimiques et physiologiques de ces interactions, de l'individu au niveau de l'écosystème. Les principales approches de mes recherches incluent des méthodes de fractionnement subcellulaire des métaux et des techniques liées à la métallomique environnementale. Les connaissances approfondies de la toxicité des métaux générées dans mon laboratoire vont contribuer à développer des outils environnementaux à utiliser pour l'évaluation de l'impact des métaux traces sur les écosystèmes aquatiques.
