Research interests
Broadly speaking, I carry out musculoskeletal epidemiology research using national health databases/registries, mainly in the areas of osteoporosis, osteoarthritis and orthopaedic surgery.
Some examples of current and past projects for which I am or have been statistician include:
- RUbICOn: examining the use, safety and long-term effects of intra-articular corticosteroid injections for osteoarthritis
- NHFD: e.g. identifying factors (patient, hospital and geographical) associated with returning home after hip fracture
- HIPPY: aiming to determine which implants are best for younger patients undergoing hip replacement
- PART: assessing the clinical and cost-effectiveness of patella resurfacing during knee replacement
- Fractures-E3: investigating fractures in Sub-Saharan Africa.
Prior to joining the University of Bristol I worked in the Centre for Statistics in Medicine (NDORMS, University of Oxford). I also undertook a DPhil using quasi-experimental approaches to estimate the impact of biologic therapy on the need for joint replacement among people with rheumatoid arthritis.
