Expertise de recherche

Au cours des dernières années, la Dr Masseau a participé à des projets de recherche scientifique fondamentale et clinique sur le diagnostic des maladies respiratoires félines et canines à l'aide de modalités d'imagerie médicale, dont entre autres, la tomodensitométrie. Elle a également développé des projets collaboratifs utilisant l'imagerie diagnostique pour diagnostiquer les maladies respiratoires chez les veaux.
