- Profile
-
I joined SCHARR in 2011 after completing a PhD in Probability and Statistics, specialising in Bayesian methods in clinical trial design at the University of Sheffield. My expertise lies in the development and application of Bayesian methods in Health Technology Assessment. My research interests include evidence synthesis methods (in particular indirect treatment comparisons with single-arm trials), survival extrapolation and structured expert elicitation.
I work as a member of SCHARR-TAG (an external assessment group for NICE technology appraisals). I have extensive experience in critiquing statistical methods used in NICE single technology appraisal submissions. I am also a member of NICE Appraisal Committee C.
I am an NIHR Advanced Fellow, currently working on a project titled “Improving the robustness of health technology funding decisions when evidence is from single-arm trials”.
