Hospital title: 
Assistant Professor in the Department of Neurology and Neurosurgery

Patrick Dion is an Assistant Professor in McGill University's Department of Neurology and Neurosurgery at The Neuro. He obtained his M.Sc. (1987-1989) and Ph.D. (1990-1995) at Université de Sherbrooke (Sherbrooke, Canada) and Université de Montréal, respectively, where he studied mechanisms of oncoviral cell transformation and the mutagenic specificity of alkylating agents at specific regions of the genome. His post-doctoral research was carried out at the Hospital for Sick Children in Toronto (1995-96) and later at the Centre for Research in Neuroscience of McGill University (2014-2016). Prior to his move to The Neuro in 2013, he was a Professor (Research) in the Department of Pathology and Cell Biology of Université de Montréal (2012-2015). Dion is interested in the identification of novel genetic risk factors in a range of neurological conditions (amyotrophic lateral sclerosis, essential tremor, restless legs syndrome) as well as in the characterization of the underlying pathogenic events associated with these risk factors. His examinations of the nuclear pore component, Gle1, in ALS opened the door to a range of examination of nuclear-cytoplasmic export defect where Gle1 is mislocalized.
