Marc Therrien is Professor in the Department of Pathology and Cell Biology of the Faculty of Medicine of the Université de Montréal and Scientific Director of IRIC.
His work on controlling the transcription of genes with Jacques Drouin at the Montreal Clinical Research Institute (IRCM) led to receiving a Ph.D. in Biochemistry at the UdeM In 1993. He then carried out postdoctoral training in molecular genetics with Gerald M. Rubin at the University of California, Berkeley, where he discovered several new components of the RAS-MAPK signalling pathway, the dysregulation of which frequently leads to cancer.
He returned to Montreal in 1999 and held a position as a Principal Investigator at the IRCM until 2003. He then joined the IRIC as one of its founding members and heads the Intracellular Signalling Research Unit. He holds a Canada Research Chair in Intracellular Signalling.
