Oscar Marín is a Professor of Neuroscience and Director of the MRC Centre for Neurodevelopmental Disorders and the Centre for Developmental Neurobiology at King’s College London. He graduated in Biology and obtained a PhD in Neuroscience from Universidad Complutense in Madrid (Spain), followed by postdoctoral training at UCSF (USA). He was a group leader at the Institute of Neuroscience in Alicante (Spain) before joining King’s in 2014. In 2005, he was selected as one of the founding members of the Scientific Council of the European Research Council, serving until 2010. He is a member of the European Molecular Biology Organization, a Fellow of the Academy of Medical Sciences, and a fellow of the Royal Society. Oscar is known for his discoveries on cerebral cortex development, with special reference to inhibitory interneurons. His discoveries have provided a novel conceptual paradigm that illuminates current research on the origin of neurodevelopmental disorders such as autism and schizophrenia. He serves on several editorial and advisory boards. He has received multiple prizes, including the Rey Jaime I Award for Basic Research (2011), Prix Roger de Spoelberch (2014), the Cajal Medal from the Spanish Royal Academy of Sciences (2017), the ECNP Neuropsychopharmacology Award (2023), and the FENS-EJN Award (2024).
