Téléphone : 519-953-6698
Courriel : justin.renaud@agr.gc.ca

Domaines d'expertise :

  • Chimie analytique
  • Analyse des toxines dans les aliments
  • Protéomique
  • Métabolomique

Projets en cours :

  • EmTOX : Réseau de recherche sur les mycotoxines émergentes dans les cultures canadiennes – CA 2. Les centres de recherche d’AAC mettent au point et standardisent des méthodes analytiques modernes pour quantifier les mycotoxines conventionnelles et les nouvelles mycotoxines
  • Exploration des collections de cultures de champignons par CPL-SM. Objectif : Créer une archive numérique du profil chimique des produits naturels issus de la collection de cultures canadiennes à Ottawa. Cette archive pourrait mener à la découverte de nouveaux bioproduits et permettra de retracer rapidement les espèces d’origine lorsque de nouvelles toxines préoccupantes sont décelées dans les cultures canadiennes
