Michel J. Tremblay, Ph.D., is a professor of virology in the Department of Microbiology, Infectious Diseases and Immunology at the Faculty of Medicine at Laval University.

He was born in Jonquière, P.Q., in 1955 and obtained in 1989 his Ph.D. degree in experimental medicine at McGill University. After post-doctoral studies in molecular immunology at the Montreal Clinical Research Institute, he founded in 1991 the Laboratory of Human Immuno-Retrovirology (LHIR) at the Research Center in Infectious Diseases Research of Laval University.

Dr. Tremblay is the author or co-author of more than 100 peer-reviewed scientific publications and 180 communications at congresses or symposia. He currently holds several grants from the Canadian Institutes of Health Research and he is the recipient of the Canada Research Chair in Human Immuno-Retrovirology (Senior level).

His research is centered on immunological and virological aspects of the human immunodeficiency virus (HIV), the causative agent of acquired immunodeficiency syndrome (AIDS).

He is studying signal transduction after contact between virus particles and their target cells, the acquisition of host-derived glycoproteins by nascent HIV and their role in viral life cycle as well as the complex interactions between HIV and opportunistic pathogens such as Leishmania and Trypanosoma parasites.
