Professional background

Sotirios Bisdas is consultant neuroradiologist and MRI lead in the Department of Neuroradiology at the National Hospital for Neurology in London, senior lecturer in neuroradiology at the Institute of Neurology University College London, and professor of radiology at Eberhard Karls University in Tübingen, Germany.

He finished his MD thesis in psychiatry after joint studies at University of Athens, Greece and University of Mainz, Germany. Dr  Bisdas was trained in Radiology and Neuroradiology at Hannover Medical School, University of Frankfurt, and University of Tübingen. He has completed a post-doctoral scholarship in Neuroradiology Research at the Medical University of South Carolina, USA. He holds a MSc degree in “Advanced Oncology” from University of Ulm, Germany and is also fellow of the European Society of Head and Neck Radiology. His expertise fields include advanced CT, intraoperative MRI, advanced and functional MRI and molecular MR-PET imaging in brain diseases.

He has authored more than 130 peer-reviewed publications (h-index > 30) and seven book chapters.

Currently, he is clinical lead of the flagship programem in neurooncology, a joint initiative of the Institute of Healthcare Engineering and the National Hospital of Neurology and Neurosurgery. Dr Bisdas serves as member of the editorial board of several leading journals in radiology and neuroradiology, is reviewer for leading journals in neuroimaging, member of the Executive Committee of the European Society of Head and Neck Radiology, and member of the Head and Neck committee of the European Society of Neuroradiology.
