Biography: 

Dr. Ziv Gan-Or is an Associate Professor at The Neuro, where he serves as the Co-Director of the Clinical Research Unit and the Director of the Neurodegenerative Disorders Research Group. Dr. Gan-Or completed his MD and PhD at Tel-Aviv University, with a major interest in lysosomal related genes and their role in the pathogenesis and progression of Parkinson’s Disease and other neurodegenerative disorders. In his lab at the Neuro, the Neurogenomics and Precision Medicine lab, Dr. Gan-Or and his team use advanced multi-omic approaches to study the effects of genetics on risk, progression and response to medications in neurodegenerative disorders. Dr. Gan-Or’s lab has a special interest in the genetics of REM sleep behavior disorder (RBD), and is leading the International RBD Genomics Consortium, with the world’s largest cohort of RBD patients. Individuals who suffer from RBD will most likely develop a neurodegenerative disease in the future: either Parkinson’s Disease, dementia with Lewy bodies or multiple system atrophy. By identifying the genetic background of RBD and by understanding how this genetic background affects the conversion from RBD to one of these neurodegenerative disorders, Dr. Gan-Or’s research aims to identify novel pathways and mechanisms that may help developing treatments. The lab collaborates with >50 collaborators worldwide, and offers a unique, supportive and stimulating environment for trainees.
