I am a biologist with a PhD in Biology from the Universidad Complutense de Madrid, where I received the Extraordinary Doctoral Award for my research on healthy aging and biological age. My scientific interests lie at the intersection of nutrition, gut microbiota, probiotics, immunology, oxidative stress, inflammation, and aging. Over the past years, I have focused on understanding how nutritional and microbiota-based interventions can improve healthspan and delay age-related decline. In particular, I have investigated the effects of probiotics such as Akkermansia muciniphila and Lacticaseibacillus rhamnosus GG, as well as other bioactive compounds, on immune function, oxidative-inflammatory status, biological age, and longevity. My research combines both animal and human studies, with the goal of translating mechanistic findings into practical strategies for healthy aging. I have authored more than 35 peer-reviewed publications in international journals and have carried out research at several institutions, including the Universidad Complutense de Madrid, CIAL-CSIC-UAM, and IBIMA-BIONAND. I also serve as a reviewer for a number of international journals in the fields of nutrition, aging, and biomedical sciences.
