David's research interests focus on the valuation of healthcare benefits. This includes describing health and valuing health states for the generation of quality-adjusted life years (QALYs) as well as the valuation and incorporation of broader outcomes (e.g. non-health outcomes or well-being) into the health technology assessment process.
David's doctoral research focuses on the application of discrete choice experiments (DCEs) in healthcare decision-making and the normative debate surrounding whose preferences should be elicited (for example see Mott and Najafzadeh, 2016). The context for this work is a public health intervention aimed at improving weight loss maintenance in obese individuals that previously lost a clinically significant amount of weight.
David joined the Office of Health Economics in March 2017. Prior to this, he was working on his PhD full-time at the Institute of Health & Society at Newcastle University. He has an MSc in Economics & Health Economics and a BSc in Economics, both from the University of Sheffield.
