Intérêts de recherche

RNA processing and stability play an important role in the regulation of gene expression. By studying factors regulating RNA stability and processing we aim at generating an integrated view of the mechanism controlling conditional RNA decay, provide a model to test in mammals and use this information as tools for diagnosis and treatment of human disease.
