Intérêts de recherche

Aging is the outcome of complex changes in our biological functions that are responsible for the increased risk of chronic diseases. The overarching goal of my lab is to decipher the etiology of aging. We aim to provide important insights into the age-related molecular changes occurring at the level of our cells and tissues, and to identify new strategies for reducing the incidence of diseases during aging.
