Mr Tzatzairis obtained his Medical degree in Democritus University of Thrace in 2010. After that, he was trained in Trauma and Orthopaedics in University Hospital of Alexandroupolis. In March of 2018 he was awarded with the MSc Certificate after supporting his thesis (graded 10/10). He is a PhD candidate, as he has already completed all of his coursework and currently is working on his thesis/dissertation. After completing his training, he was appointed as Paediatric Orthopaedic Fellow at Royal London Hospital 1 year ago where he’s working at this moment.

His main area of work was adults’ hip/knee reconstruction but he’s currently evolving his career with special interest in children’s Trauma and Orthopaedics (DDH/CTEV/Paediatric Trauma). He is an expert reviewer in several reputed journals and has numerous research publications.

Research Interest: Role of Calcium Regulating Hormones in Health and Disease. Over the Past Twenty Years His Laboratory Has Explored the Role of Vitamin D and Parathyroid Hormone Related Peptide (Pthrp) in Cancer and Musculoskeletal Disorders. His Team Was the First to Demonstrate The Efficacy of Vitamin D on Bone Aging and Prevention of Fat Accumulation in the Bone Marrow. Recently, He Co-Authored the First Evidence Linking Vitamin D Insufficiency, Muscle Fat Accumulation and Muscle Strength. His Laboratory Established the Role of the Hormone Pthrp as a Biomarker of Survival in Cancer and More Recently as a Critical Mediator of Tumor Initiation and Progression in Breast Cancer. His Clinical Research Unit Located at the Mcgill University Health Center also Participates in Major Multicenter Trials on Osteoporosis and Bone–Related Cancer Trials
