Senior Scientist, Regenerative Medicine Program
Ottawa Hospital Research Institute
Professor, Department of Medicine, Department of Cellular and Molecular Medicine
University of Ottawa

Research Interests

Research in the Megeney lab is guided by the hypothesis that apoptotic proteins and pathways evolved core non-death cell function(s). Based on this guiding principle, they are investigating the mechanisms by which metacaspases/caspases direct cell fate/cell differentiation. In addition, they are exploring how these same proteins impact a number of human diseases, including muscular dystrophy, cardiac hypertrophy/heart failure and cancer/tumour formation.
