Dr. Bertrand Routy, MD, PhD, is Assistant Professor of Hemato-Oncology and Scientific Director of the Immunotherapy and Microbiome Laboratory at the Centre de recherche du Centre hospitalier de l’Université de Montréal. He received his MD from the Université de Montréal in 2009 and his diploma from the Internal Medicine program at McGill University. He then obtained a research fellowship at Princess Margaret Hospital-Toronto University. Following his medical training, he obtained a PhD in immuno-oncology at the Gustave Roussy Cancer Campus in Paris under the supervision of Professor Laurence Zitvogel in 2017.

Dr. Routy’s work includes understanding the deleterious impact of antibiotics on patients receiving immuno-blockers (IB). He has also helped establish that the composition of the gut microbiota has a major impact on the efficacy of BCIs in non-small cell lung cancer (NSCLC) and cancer. He has written and published several important articles in journals including Science, Immunity, Cell and Annals of Oncology. Dr. Routy’s research focuses on manipulating the gut microbiome in combination with immunotherapy to develop new therapies and biomarkers in thoracic oncology.
