Celia Gregson is a Professor of Clinical Epidemiology at the Musculoskeletal Research Unit (MRU), University of Bristol and an Honorary Consultant Orthogeriatrician at the Royal United Hospital NHS Foundation Trust in Bath. She qualified in Medicine from the University of Nottingham. Following physician training she was awarded a Wellcome Trust Clinical Research Training Fellowship. She completed a one-year MSc in Epidemiology from the London School of Hygiene and Tropical Medicine and then a PhD at the University of Bristol, during which she set up and still runs the UK DINAG consortium (DXA-databases to Identify Novel Anabolic Genes). She then worked as a Senior Scientist at the MRC Lifecourse Epidemiology Unit at the University of Southampton, before taking up an Arthritis Research UK Clinician Scientist Fellowship at the University of Bristol to study the molecular genetics of High Bone Mass.

In 2018, Celia founded the ‘Sub-Saharan African MuSculOskeletal Network’ (SAMSON; www.theSAMSON.org), which she now co-directs. This network aims to build musculoskeletal research capacity across the region. Her research embedded within this network includes: (i) the IMVASK cohort study (The IMpact of Vertical HIV infection on child and Adolescent Skeletal development in Zimbabwe), a Wellcome Funded collaboration with the LSHTM and Biomedical and Research Training Institute (BRTI) in Harare; (ii) ‘VITamin D for AdoLescents with HIV to reduce musculoskeletal morbidity and ImmunopaThologY (VITALITY): an individually randomised, double-blinded placebo-controlled trial’ in Zimbabwe and Zambia which is EDCTP funded; (iii) Celia is PI on a Wellcome Trust Collaborator Award addressing ‘Fractures in sub-Saharan Africa: Epidemiology, Economic impact and Ethnography’, working with colleagues in The Gambia, Zimbabwe and South Africa; (iv) Celia is also PI of a GCRF funded study of Musculoskeletal disease during menopausal transition in the context of HIV infection in Zimbabwe and South Africa.

Celia’s research, funded by the National Osteoporosis Society (2015-2018), has identified persistent (and growing) health inequalities in hip fracture incidence and outcomes. She is currently PI on the Versus Arthritis funded REDUCE Study, which addresses unwarranted variation in the delivery of hip fracture services in England and Wales (2019-2023).

Celia is an Honorary Associate Professor at the University of the Witwatersrand in Johannesburg. She chairs the National Osteoporosis Guideline Group in the UK and sits on the Royal College of Physicians Falls and Fragility Fracture Audit Programme Scientific and Publications Committee. She is a Fellow of the Royal College of Physicians of London.
