En tant que modélisateur de l'écosystème au Centre de recherche et de développement de Lethbridge, le travail de mon équipe s'articule autour de la poursuite du développement du modèle de ferme Holos d'AAC.

Recherche et / ou projets en cours

  • Compréhension des réponses des exploitations agricoles canadiennes aux pratiques de gestion prospectives et aux changements mondiaux au moyen d'une approche écologique, basée sur les flux de carbone dans le modèle de Holos.
  • Indicateurs agroenvironnementaux de la volatilisation de l’ammoniac à l'échelle de la ferme

Énoncés de recherches/projets

  • Modélisation des écosystèmes en agriculture
  • Changements climatiques
  • Émissions de gaz à effet de serre
