Johannes Berger is Professor for Pathobiology of the Nervous System at the Center for Brain Research, Medical University of Vienna. He was formerly associate Professor for Molecular Biology at the Institute of Neurology, University of Vienna. He performed his PhD at the Sandoz Research Institute (now Novartis), Department of Antiretroviral Therapy for training in molecular biology and biochemistry. His current research activities concentrate on the role of peroxiosmes in the nervous system for health and disease. A main focus concerns the molecular mechanisms underlying X-linked Adrenoleukodystrophy and the development of novel therapeutic strategies to compensate peroxisomal dysfunction in the nervous system. He served as a coordinator in the EU projects “X-linked Adrenoleukodystrophy: pathogenesis, animal models and therapy” and “Integrated project to decipher the biological function of peroixosmes in health and disease”. He is also coordinator of the PhD program neuroscience at the Medical University Vienna.
