Research interests

The research activity is grounded in the use of computational and bioinformatic approaches for the analysis and integration of omics data applied to the study of the gut microbiota. In particular, his work employs metagenomic, metabolomic, and functional genomics analyses, combined with statistical and data science approaches, to investigate how variations in the composition and functions of intestinal microbial communities are associated with specific health conditions, both in in vivo experimental models and in human cohorts.

A central area of interest focuses on the role of diet as a key factor in modulating the gut microbiota and its impact on host physiology and health. Through functional analyses and multi-omics data integration, his research aims to identify microbial and metabolic patterns, highlighting potential biomarkers associated with different dietary regimes or nutritional factors and the resulting physiopathological changes. The overarching goal is to elucidate the mechanisms through which nutritional factors influence the gut microbial ecosystem and its interactions with the host, ultimately supporting the development of interpretable models for applications in nutritional and biomedical research.

PNRR ONFOODS (SPOKE 6) - Tackling Malnutrition


Malnutrition represents one of the major contemporary public health and social challenges, with a significant impact on health, quality of life, and resilience of the most vulnerable population groups. Within this framework, the project is embedded in the activities of Spoke 06 “Tackling Malnutrition” and aims to develop targeted and sustainable nutritional strategies for children with obesity, fragile paediatric subjects, and older adults at risk. The adopted approach is multidimensional, integrating biological, nutritional, environmental, and socioeconomic factors, and highlighting the key role of the gut microbiota in the prevention and management of malnutrition.

In this context, IBBA is strongly involved through the GLUTTON and GUITARIS projects, which focus respectively on improving infant formula composition and on targeting the gut microbiota as a nutritional lever in malnutrition and associated diseases. The activities include the identification of biomarkers, the investigation of mechanisms of action of sustainable bioactive molecules, and the evaluation of innovative and personalised nutritional interventions. The results contribute to the development of sustainable dietary models, functional foods, and evidence-based tools to support food policies, as well as dissemination and awareness-raising activities targeting vulnerable populations
