Professor Azzouz obtained a Master in Neuroscience with 1st Class Honours from the University of Marseille in 1994. In 1997 he was awarded a PhD in Neuropharmacology at the University Louis Pasteur in Strasbourg. He then worked as post-doctoral scientist at the Gene Therapy Center in Lausanne, Switzerland from 1997 to 2000.
He was recruited in 2000 by Oxford BioMedica plc as Senior Scientist then appointed as Director of Neurobiology in 2003. In 2006, he was invited to join the University of Sheffield and was appointed to the Chair of Translational Neuroscience. Azzouz is currently Deputy Head of Department, Research & Innovation.
His track record of translational research productivity is characterised by publications in top ranking scientific journals. He won prestigious awards including the ERC Advanced Investigator (2011) and ERC Proof-of-Concept (2017) Awards. These awards are top level EU ad hominem award acknowledging his pre-eminence in European biomedical research.
He is a member Panels/Boards for various funding bodies such as the Medical Research Council (Translational MRC Panel, UK), the French Muscular Dystrophy Association (AFM), the Health Research Board (HRB) of Ireland, Research Council of Norway, and the Neuroscience Panel, Germany.
He has been recently named as Board member of the British Society for Gene and Cell Therapy. He serves as Scientific Advisor for pharmaceutical companies and other organisations.
- Research interests
Professor Azzouz has achieved international pre-eminence in the field of gene therapy applications and vector development for neurodegenerative diseases. His contribution has been outstanding over the last 15 years as evidenced by the quality of publications achieved.
He has achieved a very high international status in an important field. His original and pioneering work, which has already produced major breakthroughs in animal models of neurodegenerative diseases, will in the near future, translate into major therapeutic advances in the field of human neurodegenerative disease.
Azzouz has great drive and passion to employ his scientific skills for the ultimate benefit of patients and families suffering from some of the most devastating diseases in medicine.
Azzouz achievements went beyond therapy development. Indeed, he also made significant discoveries related to the mechanisms of diseases in ALS/MND and SMA. For example, The recent discovery of the mechanism underpinning genome instability and neural cell death caused by C9orf72 expansion in ALS [Nature Neuroscience 20(9):1225-1235. (2017)] and role of PTEN in ALS and SMA [Human Molecular Genetics, 19(16):3159-68 (2010); Brain, 134(Pt 2):506-17 (2011)].
His exceptional achievements were recently recognised at the European level by winning the prestigious ERC Advanced Investigator and ERC PoC Awards designed for individuals with excellence in scientific research. These awards offer him a platform to cement his European leadership in the field of gene therapy and translational neuroscience.
