De Gregorio Danilo Ricercatore a tempo determinatoMedicineBIO/14 - Farmacologia




Danilo De Gregorio obtained a Pharm.D. degree from the University of Naples “Federico II”, Italy, followed by a Ph.D. in Neuropharmacology from the University of Campania “Vanvitelli”, Naples, Italy. He trained as a postdoctoral fellow at the Department of Psychiatry, McGill University, Montreal (QC), Canada under the supervisions of Prof. Gabriella Gobbi and Prof.  Nahum Sonenberg. Since March 2021, he holds the position of Assistant Professor of Pharmacology, Vita-Salute San Raffaele University. By combining cutting-edge in vivo behavioral and electrophysiological techniques in animal models, Danilo has made contributions to the understanding of the psychopharmacology of psychoactive compounds including hallucinogens and cannabinoids and their role in mental disorders.  His work has been published in relevant scientific journals (including Nature, PNAS, Nature Communications). He has received numerous awards for his work including the Canadian Institute of Health Research (CIHR) grant and the Fonds pour la recherche en Santé du Québec.
