Fonctions

PERSONAL STATEMENT

My research mainly focuses on the epidemiology of aging, with the aim of understanding how environmental factors, in particular diet, influences the etiology of brain diseases and conditions in aging such as dementia and cognitive decline. I have been working on several large cohorts, including the French Three-City study and Harvard cohorts (Nurses’ Health Study and Women’s Health Study), and developed a multidisciplinary epidemiological expertise across nutrition, neurosciences, applied biostatistics and brain imaging. I have evidenced protective associations between fish and marine omega-3 fatty acids, olive oil, overall healthy diets and exposure to multiple nutrients, and a lower risk of various age-related brain diseases. Since environmental factors have a pleiotropic role in health, a broader perspective of my research has focused on the impact of a healthier diet in midlife (eg., a Mediterranean diet) for healthy aging.

There is increasing evidence that a number of age-related diseases are determined by exposures over the entire life-course. For example, cumulative environmental exposures throughout life may modulate the burden of lesions and resilience capacities of the aging brain, which are the two core neuro-pathophysiological components of Alzheimer’s dementia. Hence, it has become more and more evident that future brain aging research should move on early prevention. In this context, my research objectives are two-fold. First, I aim at identifying in prospective cohort studies the time window and the mechanisms linking environmental risk factors to brain health, by using (i) dynamic methodological approaches to investigate risk factor trajectories, and (ii) innovative markers of exposures (eg, metabolomics), outcomes (eg, brain imaging markers) and mechanisms (eg, neurogenesis) across both young and older populations. Secondly, I work on the identification of relevant targets (population, intervention) for early prevention. This includes exploration of gene-by-nutrient interactions in cognitive decline and dementia and investigation of potential novel preventive agents/combination through both candidate and untargeted, agnostic approaches applied to various omics data.
