Son domain d'expertise porte sur l'impact de la nutrition sur la longévité en santé, en particulier sur la santé musculaire et cérébrale. Elle intègre des technologies innovantes telles que la métabolomique, la protéomique et les applications mobiles pour mieux comprendre les mécanismes sous-jacents et pour identifier des biomarqueurs nutritionnels. Son objectif est de contribuer au développement de stratégies nutritionnelles personnalisées pour promouvoir la santé à long terme et prévenir les maladies liées au vieillissement. Ses travaux incluent des études épidémiologiques traditionnelles et incluant la métabolomique et la protéomiques plasmatique et cérébrales, des essais d'intervention, ainsi que des études de validation.
