My research in epidemiology focuses on the food exposome and brain aging, with main interests in:

  • Nutritional risk and protective factors for cognitive decline and dementia
  • Statistical modeling of nutritional exposures such as multi-nutrient patterns and networks
  • Molecular epidemiology of diet and brain aging especially nutritional metabolomics
  • Inter-individual variability in biological responses to dietary exposures, including genetic and microbiota influences
