Dr. Marc-Emmanuel Dumas is Adjunct Professor at McGill and Chair in Systems Medicine at Imperial College London. He develops novel research avenues in the field of metabolomics in systems medicine, targeting mostly metabolic and cardiorespiratory diseases but also chronic inflammation, brain health and cancer.  He studies the undermining biology leading to metabolic variations observed in these various contexts using genomics, metagenomics and cellular networks. Dr. Dumas has discovered that many microbial metabolites are bioactive and he focusses on identifying causality chains involving these metabolites as well as host targets they engage with.
