My research in molecular epidemiology focuses on environmental exposures (e.g. diet and pollutants) and brain aging, with main interests in:

  • Lifestyle (mainly nutritionnal) risk and protective factors  for cognitive decline and dementia
  • Statistical modeling of complex environmental exposures such as multi-nutrient patterns and multi-pollutants networks
  • Exploring the blood exposome (food metabolomics, chemical exposomics…) to identify biomarkers of exposure and biological responses related to brain aging
  • Integrating omics technologies to decipher the biological mechanisms linking environmental exposures to brain health and aging
  • Inter-individual variability in biological responses to dietary exposures, including genetic and microbiota influences
