My research area aims to contribute to the definition of a healthy and sustainable diet, particularly regarding the role of dietary fibers, proteins, and the gut microbiota, to advance the design of next-generation food supplements, food ingredients, and further contribute to food-based dietary guidelines.

Scientifically, my focus lies on the study of dietary fibers and proteins, specifically studying their chemical structure and features, in order to allow a detailed link between structure and health-promoting properties (function). This will include studying how these nutrients interact with the gut microbiota and gut cell models to modulate digestive, metabolic and immune functions.

Beyond the scientific contribution, this research holds strong societal relevance. By demystifying the role of carbohydrates—often misunderstood as harmful components of the diet—and by valorizing food industry side streams as sources of functional ingredients, my work aims to promote sustainable and evidence-based nutritional solutions.
