Celia Gregson is a Consultant Senior Lecturer in Musculoskeletal Medicine at the Musculoskeletal Research Unit (MRU), University of Bristol and is 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 3-year Wellcome Trust Clinical Research Training Fellowship, completing a one-year MSc in Epidemiology from the London School of Hygiene and Tropical Medicine and 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 worked as a Senior Scientist at the MRC Lifecourse Epidemiology Unit at the University of Southampton, prior to taking up an Arthritis Research UK Clinician Scientist Fellowship working on the molecular genetics of High Bone Mass at the University of Bristol. In research, funded by the National Osteoporosis Society, Celia identified persistent (and growing) health inequalities in hip fracture incidence and outcomes. She is now 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). 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 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) the GCRF Menopause Study which aims to understand musculoskeletal health in the context of HIV infection in women transitioning through menopause in Southern Africa; and (iv) Celia is PI on a NIHR-Wellcome Trust Partnership funded Collaborator Award for ‘Fractures in sub-Saharan Africa: Epidemiology, Economic impact and Ethnography’ in South Africa, The Gambia and Zimbabwe. Celia chairs the UK National Osteoporosis Guideline Group.
