Rodrigue Rossignol is a research scientist hired by the French National Institute for Science and Medical Research (INSERM). He performed doctoral studies in Bordeaux and a postdoc at the University of Oregon (Rod Capaldi group). Dr. Rossignol is a member of the directing committee of the Laboratory of Rare Diseases, Metabolics and Genetics (MRGM) in Bordeaux at the University of Bordeaux Segalen and Bordeaux Hospital. His fundamental and biomedical research is focused on the study of energy metabolism in humans, with a particular emphasis on the regulation of oxidative phosphorylation and mitochondrial physiology. This led him to investigate the mechanisms of mitochondrial bioenergetic and morphodynamic dysfunction in metabolic diseases as diverse as pure mitochondrial neuromuscular disorders, common neurodegenerative diseases and cancer. Dr. Rossignol has published 50 articles in the field of cellular bioenergetics and co-chairs the International Society of Mitochondrial Physiology (http://www.mitophysiology.org/). He is section editor of the Organelles In Focus series at the international Journal of Biochemistry and Cell Biology (IJBCB).
