The main research focus of our group involves an Integrative Systems Medicine approach, with a particular emphasis on understanding the role of the gut microbiome in ageing, cognitive performance, and metabolic and mental health. To achieve our objectives, we undertake highly multidisciplinary research that combines cutting-edge post-genomic technologies—including shotgun metagenomics, NMR and HPLC-MS/MS metabolomics and lipidomics, and RNA sequencing, among others—with advanced computational bioinformatic techniques such as machine learning, chemometrics, and multivariate statistics.

The group has extensive experience in bioinformatic analysis of single-omics datasets and integrating omics data. Our research is conducted on large human cohorts and validate our findings using pre-clinical models such as mice and Drosophila melanogaster.

Our ultimate goal is to mine and integrate high-throughput omics and clinical data to obtain a holistic understanding of the complex host-microbiome interactions and the multifactorial, heterogeneous nature of non-communicable diseases. Through this work, we seek to elucidate the molecular mechanisms underlying health and disease. We strive to identify new biomarkers or signatures that can serve as the foundation for developing efficient personalized, tailor-made therapies, as well as diagnostic, prognostic, and monitoring tools for clinical translation.

Main lines of research

- Role of the microbiome on metabolic health (e.g., obesity, MASLD, diabetes), behaviour (food addiction), cognitive performance, mental health (depression, anxiety), and neurodegenerative disorders (Alzheimer’s disease)

- Influence of non-bacterial biomes (viruses, archaea, protists, and fungi) in cognition and metabolic and mental health

- Gut microbial metabolism of histidine in MASLD and other obesity-related metabolic diseases

- Gut microbial regulation of tryptophan metabolism in cognition and mental and metabolic health.

- Impact of the microbiome-gut-brain axis and the fat-brain axis on depression

- Role of the gut microbiome in the early stage and progression of Alzheimer’s disease

- Role and mechanisms of the gut microbiome in ageing and age-related cognitive decline

- Influence of the gut bacteria and viruses on food addiction.

Strategic objectives

Our key objectives are:

  • Understanding the complex nature of non-communicable disease (obesity, diabetes, MASLD, mental and neurological disorders)
  • Elucidating the role of the intricate host-microbiome interactions
  • Unravelling the underlying molecular mechanisms
  • Developing more efficient, personalized, tailor-made, and easily accessible treatment options, as well as better diagnostic, prognostic, and monitoring tools.

To achieve these objectives, we aim to:

  • Incorporate a pan-kingdom view of the microbiome (including largely neglected members such as viruses or eukaryote) and conduct a thorough functional profiling (combining metagenomics with metabolomics), to effectively capture host-microbiome interactions.
  • Identify single-omics signatures in longitudinal and large-scale cohorts.
  • Validate the identified profiles in independent cohorts.
  • Integrate single-omics profiles with clinical and neuroimaging data (MRI-based radiomics) to obtain a holistic picture of the mechanisms underlying the gut microbiome-host interactions.
  • Assess the potential causal role of the gut microbiota species/genes, their metabolites, and miRNAs in cells, mouse (e.g. Fecal Microbiome and Viral Transplantations) and fly models (e.g. mono-colonization with candidate species, dietary supplementation with selected metabolites, etc).
