Marion Leboyer, M.D., Ph.D. is Professor of Psychiatry at University of Paris Est (UPEC) in France. She is head of the University-affiliated department of Psychiatry and Addiction (Mondor, hospital, AP-HP). Since 2007, she is CEO of “fondation FondaMental” (www.fondation-fondamental.org) which enabled the creation of national networks of 44 expert centers which are diagnostic and research platforms throughout France, leading to the construction of large databases and biobanks which serve as shared infrastructures for research in France.

She also runs the Inserm “Translational Psychiatry” laboratory (Mondor Institute for Biomedical Research) whose aim is to search for better understanding of underlying environmental and genetic risk factors in severe psychiatric disorders. Based on deep phenotyping of large cohorts of patients, gathering biological (genetic and immuno-inflammatory) and brain imaging data, their goal is to identify specific biomarkers to develop precision medicine.

Her research efforts have contributed to produce prominent findings such as identification in autism of the first mutations of genes implicated in synaptogenesis (Jamain et al, 2003) or immune dysfunctions observed in psychiatric disorders, such as auto-immune psychosis (Jezequel et al, 2017). She has also been part or brain imaging programs, demonstrating cerebellum abnormalities in autism (Laidi et al, 2017) or fronto-striatal loop in bipolar disorders (Houenou et al, 2007). Cost analysis studies demonstrated high care cost and low research funding in psychiatry in France (Chevreul et al, 2012). Dr. Leboyer has authored or co-authored more than 400 peer-reviewed international publications (H-factor = 71).
