Dr. Tomás Meroño
Dr. Tomás Meroño
Dr. Tomás Meroño is a Lecturer Professor at the Department of Nutrition, Food Sciences, and Gastronomy of the University of Barcelona (One approved research six-year period). His research aims to describe the relationships between diet, gut microbiota, inflammation, and healthy aging. In the last 3 years, Dr. Meroño led 10 articles aiming to describe the relationship between diet, gut microbiota, and healthy aging through nutritional epidemiology and nutrimetabolomics studies. Specially he was leader of a paper showing a nutrigenetic interaction between fibre consumption and APOE gene variants for cognitive decline risk (Age & Ageing, 2023, several news outlets published). Currently, Dr. Meroño is PI from a research project funded by the “Agencia Estatal de Investigación, MICINN” for studying the role of intestinal permeability and bacterial translocation in brain health -BTsBRAIN-PID2021-128542OA-I00. Part of this project involved the improvement of the methodology to evaluate circulating LPS subtypes based on the chain length of 3-hydroxy fatty acids present in lipid A. Moreover, he coined the term “good” LPS for LPS coming from Gram-negative gut commensals of a healthy gut microbiome in his recently published seminal paper (doi: 10.3389/fimmu.2025.1588129). BTsBrain publications are now written showing the association between “good” LPS and brain health measurements (2 poster presentations). In addition, TM participated in two industry-funded research projects in patients with Rheumatoid Arthritis (PI. Enrique Soriano): i) funded by Roche Farma S.A., showing no impact of tocilizumab treatment on lipid parameters, published in 2021; and the other ii) funded by Pfizer S.A, manuscript published in 2025. Last, TM is actively collaborating in several EU competitive projects funded by the JPI-HDHL regarding the health effects of diet: i) Tailored Carbohydrate Quality for Personalized Weight Management and Metabolic Health (AC19/0011), ii) Diet and microbiome based metabotypes to adapt intervention strategies for health improvement, DIGUMET (PCIN-2017-076), and iii) Knowledge Platform on Food, Diet, Intestinal Microbiomics and Human Health (AC19/00096). Last, he is part of the Biomedical Research Network Center in Fragility and Healthy Ageing CIBERFES (CB16/10/0026).
Overall, Dr. Meroño co-authored 77 publications indexed in the JCR, most of them published in journals in the first quartile of his specialty (H index: 16, citations: 816, WOS). During the period 11/2023-04/2024 he enjoyed paternity leave. The international collaborations of Dr. Meroño include Dr. Antonio Cherubini (IRCCS-INRCA, Italy), Dr. Simone Guglielmetti (University of Milan, Italy), Dr. Anatol Kontush (INSERM, France), Dr. Fernando Brites (University of Buenos Aires, Argentina) and Dr. Rikard Landberg (UChalmers, Sweden). In particular, during the doctorate, TM carried out a 3-month research stay in the laboratory of Dr. Anatol Kontush (INSERM UMR ICAN 1166) which led to four joint publications in lipidomics.
TM is currently co-director of three PhD Students at the University of Barcelona. TM is regular reviewer of research projects in Food and Agricultural Area-Foods subarea of the Spanish Agency of Research (since 2024), for the Applied Medical Research and Development projects presented to Czech Health Research Council (AZVCR) and the Czech Science Foundation (since 2017) and is Reviewer Editor of Frontiers in Immnunology.
