I conducted my PhD at the University of Montreal under the supervision of Dr. Jacques Thibodeau after which I joined the group of Dr. John Bell as a postdoctoral fellow in Ottawa. Now that I am an independent scientist at the “Institut du Cancer de Montréal” and at the “Centre de Recherche du CHUM”, my work specializes on cancer immunotherapy. More specifically, how to use viruses to specifically kill cancers as well as to create anti-cancer vaccines. These so-called oncolytic viruses constitute a novel form of immunotherapeutic cancer treatments.

Research topics

Our research team studies the use of oncolytic viruses for cancer immunotherapy.

More specifically, our research program includes 3 main facets:

  • The use of oncolytic viruses as platforms for personalized anti-cancer vaccination
  • The development of novel vaccination strategies using oncolytic viruses and bacteria
  • The study of the role of the immunoproteasome for the immunotherapeutic activity of oncolytic viruses
