Mes recherches portent sur l'étude des facteurs de l'hôte impliqués dans la réponse aux communautés microbiennes qui vivent en biofilms à la surface de la muqueuse intestinale. Je cherche à comprendre comment une mauvaise régulation de ces facteurs peut modifier de façon délétère les biofilms microbiens, et contribuer à la physiopathologie de maladies digestives inflammatoires et infectieuses. Ces recherches visent aussi à développer des stratégies pour restaurer l'équilibre hôte/biofilm dans l'intestin, et d'offrir de nouvelles pistes thérapeutiques pour le traitement de patients atteints de maladies digestives.
My research interest broadly relates to host and microbial biofilms interactions in the gut. I am studying how dysregulation in the production of host factors (for instance, epithelial proteases) leads to biofilm alterations, and participate in the pathophysiology of inflammatory and infectious intestinal diseases. Importantly, I am evaluating strategies to restore homeostatic epithelium/biofilm crosstalk with the hope of gaining insights for future treatment options for diseases affecting intestinal tissues.
