Research interests


  • Microbial multicellularity phenomena, with a special focus on the bacteria Pseudomonas and Burkholderia
  • Identification and elucidation of intercellular communication mechanisms (`quorum sensing’) in bacteria
  • “Swarming” motility and its role in the development of microbial communities (biofilms)
  • Bacterial physiology
  • Functional genomics approaches
  • Biosurfactants (rhamnolipids)
  • Secondary metabolites
  • New antibiotics and anti-pathogenesis alternatives

Dr. Eric Déziel obtained his B.Sc in microbiology/immunology and biotechnology from McGill University (1993), his M.Sc. in applied microbiology from the Institut Armand-Frappier (1996), and his Ph.D. in environmental engineering from the École Polytechnique de Montréal (2001). Following postdoctoral training in bacterial pathogenesis at the Harvard Medical School (Boston), he joined the INRS-Institut Armand-Frappier in January 2005 as an Assistant Professor.

His research projects focus on the bacteria Pseudomonas aeruginosa and Burkholderia are aimed at a better understanding of multicellularity phenomena, such as cell-to-cell communication and swarming motility, in microorganisms.

Dr. Déziel holds the Canada Research Chair in sociomicrobiology.
