Mandy is the Director of the Health Economics Research Unit. She joined HERU in 1987 after graduating from the University of Leicester with a BA (Hons) in Economics and the University of York with an MSc in Health Economics. In 1995, she graduated from the University of Aberdeen with a PhD in Economics concerned with the application of contingent valuation and discrete choice experiments (DCEs) in health economics. In 1997, Mandy was awarded a five-year Medical Research Council Non-Clinical Senior Fellowship to develop and apply DCEs in healthcare. In 2002, she was awarded a Personal Chair in Health Economics by the University of Aberdeen and in 2006 she was elected as a Fellow of the Royal Society of Edinburgh. She took up the Directorship of HERU in April 2013.

Mandy's research interests focus on taking a person-centred approach to valuation in health economics. She is known for her work challenging the clinical approach to valuation that is often adopted by health economists and for developing alternative person-centred approaches. She introduced DCEs into health economics in the early 1990s and her research has applied DCEs in a wide range of contexts to take account of the user preferences in the delivery of healthcare.

Research Overview

Mandy's research interests focus on taking a person-centred approach to valuation in health economics. She is known for her work challenging the clinical approach to valuation that is often adopted by health economists and for developing alternative person-centred approaches. She introduced discrete choice experiments (DCEs) into health economics in the early 1990s and her research has applied DCEs in a wide range of contexts.

Current Research

Mandy is currently applying DCEs to address a range of policy questions, including: informing shared decision making (developing a Decision Aid Tool); investigating if Scotland should provide Whole Genomic Sequencing for the diagnosis of rare diseases; professional preferences for referral to Intensive Care Units; women's preferences for treatment of metastatic breast cancer; preferences for allocation of time following a breast cancer diagnosis; and preferences for government responses to a pandemic. 

Mandy also conducts methodological work to inform future practice for the design and analysis of DCEs. Current research interests include: using eye-tracking methods to understand how individuals respond to DCEs; experiments to explore the external validity of DCEs (do individuals behave in reality as they state in hypothetical surveys); and understanding how best to include the cost attribute in DCEs.
