Dr. Fabrice Lejenue studies the mechanisms that regulate or deregulate the quality control of protein synthesis with the aim to one day utilize these mechanisms to chemically treat diseases such as cystic fibrosis, muscular dystrophy and cancer. He studied under Dr. Lynne Maquat, Director, Center for RNA Biology, and the scientist responsible for discovering the control mechanism messenger RNA carrying nonsense mutations in mammals. Dr. Lejeune continues this work at his lab at the Pasteur Institute.
