Hugh Willison is Professor of Neurology at the University of Glasgow. He has pioneered the global effort to understand the aetiological basis for the major cause of acute neuromuscular paralysis worldwide, Guillain Barré syndrome. His work generated a mechanistic model of acute immune-mediated nerve injury that has been adopted worldwide as the gold-standard. Recently he has been involved in the effort to understand Zika virus-associated GBS, studying epidemics throughout Latin America via European Union projects. Professor Willison is co-director of the European School of Neuroimmunology that has trained over 4000 young scientists and clinicians over 20 years.
