Dr. Marc Ouellette is an investigator at the Infectious Diseases and Immunity Axis of the Research Centre of the CHU de Québec-Laval University. He is also a full professor at the Department of Microbiology-Infectious Diseases and Immunology at the Laval University School of Medicine. His work focuses on antimicrobial resistance. Dr. Ouellette holds a Canada Research Chair in antimicrobial resistance and was the Scientific Director of the CIHR Institute of Infection and Immunity from 2010-2018. He is a fellow of the Royal Society of Canada and of the Canadian Academy of Health Sciences.

Dr. Ouelette’s work focuses on the protozoan parasite Leishmania and on different bacteria, including the pneumococcus. Leishmania is a neglected tropical disease that affects over 12 million people, while antibiotic resistance is a major public health issue that is receiving unprecedented political attention. His team uses several screens coupled to next-generation sequencing to find novel biomarkers of resistance in parasites and bacteria. Their screens are also used to identify new drug cellular targets against new molecules or also to define death and survival pathways that could be exploited for novel therapeutic strategies.
