Research interests
I am a health economist with over ten years experience on choice experiments, outcome measurement, economic evaluations, and disease burden and quality-of-life studies in multiple clinical fields. I joined the Musculoskeletal Research Unit (MRU) and the Health Economics at Bristol (HEB) group, UoB as a senior Research Associate in Oct 2021. I use patient-level data from trials to perform economic evaluations, and routinely collected observational data from large national databases to cost resource use in hip fracture to inform initiatives targeting improved provision of hip fracture services.
I am currently involved in the Versus Arthritis funded REDUCE Study, which addresses unwarranted variation in the delivery of hip fracture services in England and Wales (2019-2023), and in the SISMIC Study: A Randomised Controlled Trial of Scaffold InSertion and MIcrofracture Compared to Microfracture Alone for the Treatment of Chondral or Osteochondral Defects of the Knee.
I am holding a research collaboration grant with Obuda University (Hungary) on the ‘Development and evaluation of innovative and digital health technologies’ within the Thematic Excellence Programme of the National Research, Development and Innovation Fund, Hungary (2023-2025).
From July, 2023, I am co-leading a work package in the ‘Hip Implant Prosthesis Programme for the Younger total hip replacement patient (HIPPY)’, (PGfAR-NIHR203671,£2,9M, 96 months) conducting a discrete choice experiment on preferences of patients and clinicians for different hip implants and hip replacement outcomes.
