His general aim is to develop personalized therapy in psychiatry, based on the more recent molecular knowledge. He is determined to transfer the scientific knowledge from the bench to the bedside, to improve the clinical care in psychiatry. As a researcher, he explores the epigenetic and transcriptomic mechanisms of the onset of psychosis and the genetic factors associated with extreme phenotypic forms, like childhood-onset schizophrenia. As a clinician, he is involved in the specialized clinic for „Rare Diseases“ (Center of Reference for Rare Psychiatric Diseases) in the GHU Paris Psychiatry and Neurosciences.
