I am a health economist working in musculoskeletal and surgical cost-effectiveness research affecting millions of patients worldwide.  I collaborate with national and international academic institutions and industry to design and deliver large programmes of research. Recent clinical areas I have worked on include orthopaedic surgery in trauma and elective hip, knee, and ankles surgery; rheumatology; medical devices; breast cancer; obstetrics; stroke; children with cronic conditions; and evaluation of NHS services delivery.

I am chief investigator an NIHR-funded Programme Grant for Applied Research of circa £3m in collaboration with Ashley Blom (co-CI, Sheffield), Mike Whitehouse (UoB, THS), Mike Reed (Northumbria, NJR) and David Sochart (SWLEOC) and numerous other researchers in Bristol and beyond. HIPPY (Hip Programme Prosthesis Study for the Younger THR patients) is a programme of studies in evidence synthesis, large linked RWE data analyses, and economic modelling to find out which implants are best for patients under 70 years of age. It includes the largest surgical trial in orthopaedics where we will randomise nearly 8,000 elective hip replacement patients under 70 years to receiving cemented, uncemented, or hybrid implants in circa 100 hospitals across England and Wales who we will follow-up for 10 years after surgery. My interests lie in using evidence synthesis methods and "big data" from national and international sources to inform cost-effectiveness models. I lead two completed NIHR grants using these methods to determine the cost-effectiveness of multiple types of hip and knee implants. I lead or co-lead the economic evaluation components in research infrastructure grants such as the contact for analyses of NJR data and the Bristol NICE Technology Asssesment Group and over 20 other NIHR funded studies based at Bristol, Oxford, and other organisations across the UK. 

I serve in the NIHR Programme Grants for Applied Research sub-panel research committe after six years serving in the NIHR Research for Patient Benefit  - Southwest regional advisory panel. I provide advice to NICE and INFARMED technology appraisal committee expert board (NICE equivalent in Portugal) appraising submissions of medicines for approval in the English and Portuguese NHS.

I supervise three PhD students in health economics-related topics, lead the Evidence-Based Practice in Medicine helical theme lead for the undergraduate medical programme MB21, co-lead of the Quantitative methods for economic evaluation and policy analysis module of MSc Health Economics and Policy Analysis, and contribute to teaching and organisations in many other MSc and CPD short courses delivered at Bristol and abroad. 

I have a PhD in Economics, having studied economic theory and finance in post-graduate programmes in the USA and Portugal. My dissertation looked at economic growth models and tested the (endogenous) influence of population growth on economic growth in 202 countries.
