Dr. Jordi Mayneris-Perxachs holds two BSc in Chemistry and Food Science and Nutrition with honors and a PhD in Theoretical and Computational Chemistry. He is an expert in Systems Biology and Omics Sciences, particularly metabolomics, metagenomics and transcriptomics. He acquired most of this expertise during a four-year post-doctoral stay (2011-2015) at the University of Reading and Imperial College London (UK) under a Marie Curie COFUND programme. There, he pioneered the description of gut microbial-derived alterations in Tryptophan metabolism with undernutrition and environmental enteropathy applying a metabolomic approach. In 2015, he was granted a Marie Curie fellowship (Tecniospring programme) to join the Units of Nutrition and Omics Science at the Technology Centre of Catalonia (EURECAT). In 2019, he was granted a Miguel Servet (ISCIII) and joined the Girona Biomedical Research Institute (IDIBGI), where he leads the Integrative Systems Medicine research. He applies cutting edge post-genomic technologies combined with advanced computational techniques (i.e., machine learning) in large human cohorts and pre-clinical models to obtain a holistic view of the holobiont and unravel the molecular mechanisms underlying the pathogenesis of cardiometabolic disease and cognitive performance, with particular emphasis on the complex microbiome-host interplay. He has led the discovery of microbial profiles and functional signatures linked to memory, inhibitory control, depression and fatty liver, publishing the results in high-impact journals such as Cell Metabolism (IF=31.373), Gut (IF=31.793), Cell Host & Microbe (IF=31.316) and Microbiome (IF=16.859).
