I am Professor of Health Economics and Decision Modelling at ScHARR, University of Sheffield, England. I studied for BSc Mathematics at Imperial College London and then MSc Operational Research at the London School of Economics before joining the NHS to work in and then lead a modelling team which I moved to ScHARR when it was set up 25 years ago. I lead a large group of around 35 academic staff, undertaking methodological and applied research and consultancy using mathematical modelling in health and healthcare.  I have been developing and applying modelling in support of healthcare decision-making nationally and internationally, across a large range of diseases, interventions, service planning and policy issues for over 25 years. I am a regular expert on several NICE Scientific Advice Programme panels, providing input to the design of phase III studies from an economic/NICE perspective, usually for global pharmaceutical and device manufacturers.

My fundamental interest is in mathematical modelling approaches to inform decision making in health and healthcare. I am currently principal investigator or co-investigator involved in over 19 research programmes and projects. Applied areas include alcohol, tobacco, diabetes and cardiovascular disease modelling.  Methods interests include cost-effectiveness modelling in public health and HTA, simulation and agent based modelling, calibration, inequalities and expected value of information approaches.
