Professor Marc-Emmanuel Dumas, PhD MEng MSc BEng BSc FRSB FRSC
Marc-Emmanuel Dumas is Chair in Systems Medicine, a joint appointment between the Department of Metabolism, Digestion and Reproduction's section of Biomolecular Medicine and the National Heart and Lung Institute's section of Genomic and Environmental Medicine.
Professor Dumas is head of the Section of Biomolecular Medicine, which hosts state-of-the-art equipment dedicated to metabolomics, crystallisation science and tissue culture.
Professor Dumas is also the founding director of Imperial's Microbiome Network, a cross-faculty multidisciplinary network of excellence made of >60 PIs and their groups to consolidate research, teaching and public engagement activities around the microbiome.
Professor Dumas develops novel research avenues in the field of metabolomics, microbiomics in systems medicine, targeting mostly the role of the microbiome (but not limited to) in metabolic and cardiorespiratory diseases as well as in chronic inflammation (including neuroinflammation) and certain types of cancers.
Professor Dumas currently holds an Adjunct Professorship at McGill University's Genome Innovation Centre and Department of Human Genetics in Montréal, Canada, and an open-ended appointment as CNRS principal investigator in France.
Prior to this, he was appointed at Imperial as Lecturer (2009-2013), Senior Lecturer (2013-2015) and Reader (2015-2018). He took his CNRS position at Ecole Normale Supérieure de Lyon in 2007, where he started a metabolomics and systems biology group and was awarded a Young Investigator Award from the Agence Nationale de la Recherche.
He studied in France and qualified as an Engineer in Agronomy (MEng, Ingénieur Agronome) in 1998 with two MSc in "Biochemistry & Genetics" and "Applied Physiology", before being awarded a PhD in "Biochemistry, Molecular and Cell Biology" in 2002 and joining Imperial to coordinate the metabolomics team of the Wellcome Trust-funded Biological Atlas of Insulin Resistance consortium (BAIR), where he led pioneering research on the role of microbial metabolites in non-alcoholic fatty liver disease, insulin resistance and type 2 diabetes.

Prof. Dumas’ research interests in systems medicine include metabolomics, quantitative genetics, metagenomics and network biology, more specifically integration of metabolomic data with other "omics" (transcriptomics, proteomics, genome polymorphism and metagenomics) to identify metabolites and genes associated with metabolic and cardiorespiratory pathologies, ie insulin resistance, metabolic syndrome, type 2 diabetes, obesity, asthma, dyslipidemia, atherosclerosis, hypertension, non-alcoholic fatty liver disease, but also ageing and cancer. This functional integration of "omics" sciences identifies candidate drug targets for mechanistic validation.
Prof. Dumas’ contribution to insulin resistance research was the identification of a gut microbiota – related metabolic phenotype (or “metabotype”) in non-alcoholic fatty liver disease. Methylamines (monomethylamine, dimethylamine, trimethylamine and trimethylamine-N-oxide), a class of microbial metabolites derived from dietary choline-containing compounds, are associated with the development of insulin resistance, and more specifically non-alcoholic fatty liver disease. This observation on gut microbial metabolism brought an independent confirmation of several previous findings in metagenomic projects from a metabolic point of view. Methylamines are now thought to be involved in other insulin resistance related pathologies such as atherosclerosis.
In terms of systems biology modeling, Prof. Dumas is one of the pioneers in the field of Metabotype Quantitative Trait Locus (mQTL) Mapping and Metabolome-wide Genome-Wide Association Studies (i.e., metabolomic GWAS), by integrating genome-wide polymorphisms with metabolome-wide quantitative variation. Dr. Dumas now develops the concept of microbiome-wide metabolome-wide association studies (MW2AS), combining High-Throughput Sequencing and Metabolic Profiling technologies. Prof. Dumas has also developed a keen interest in knowledge visualization and integration of metabolic signatures with protein-protein interaction networks (interactome), and recently introduced a new approach to understand the regulation of metabolic patterns, by mapping metabolic networks onto protein-protein interaction networks: integrated metabolome and interactome mapping (iMIM).
Prof. Dumas introduced the concept of "Metabolomics-on-a-chip", i.e. the hyphenation of bioartificial organs based on microfluidic biochips with metabolic profiling technologies, and pioneered applications for in vitro predictive systems toxicology and pharmacology.
