Dr Julien Baruteau

Consultant Metabolic Paediatrician


Dr Baruteau graduated as a Medical Doctor and Specialist in Paediatrics from Toulouse University in 2004. He specialised in Paediatric Inherited Metabolic Medicine in 3 different tertiary metabolic centres in Paris and Toulouse, France then in London. He was appointed as Consultant in Paediatric Metabolic Medicine at Great Ormond Street Hospital for Children in London in 2017. 


Dr Baruteau is a clinical academic with a strong commitment to basic and clinical research. He is a Group Leader at University College London Great Ormond Street Institute of Child Health. He has been awarded prestigious fellowships to pursue his clinical and academic career: Action Medical Research Training Fellowship, NIHR GOSH Biomedical Research Centre Catalyst Fellowship, MRC Clinician Scientist Fellowship. He was promoted as Principal Research Fellow (Equivalent of Associate Professor) in 2022. His research focuses on studying the pathophysiology and developing novel therapies for inherited metabolic diseases. He has developed gene therapy using both viral and non-viral vectors and is the UK chief investigator in first-in-human gene therapy clinical trial. He has expertise in translating academic and industry-led programmes of gene therapies. He is the member of experts’ committees from the European Society of Gene and Cell Therapy, the American Society of Gene and Cell Therapy and the European Society of Human Genetics. He has served as expert for the French medicine agency “Agence nationale du médicament et des produits de santé” for 10 years. He has authored >70 scientific articles.  


Dr Baruteau is an invited member of the scientific board of the UK-based Children’s Liver Disease Foundation.
