Cláudia Marques

Professor Professor Auxiliar
Researcher | Nutritionist

Assistant Professor at NOVA Medical School, instructor for the courses “Human Nutrition” and “Research Methodologies in Nutrition” in the Bachelor’s Program in Nutrition Sciences.

She is a researcher at CHRC and co-founder of YourBiome, a spin-off from NOVA University Lisbon, which aims to develop new therapeutic solutions based on fecal microbiota. Her main areas of interest and research are: the effect of dietary interventions on the composition and function of the gut microbiota and its relationship to health and disease, particularly obesity and type 2 diabetes.

She has published dozens of scientific articles in national and international scientific journals in the field of gut microbiota.
