Hareth holds a Wellcome Trust Investigator Award (2021-2025) to study how and why schools and workplaces invest in mental health and wellbeing (the WISE project) Wellbeing Investments in Schools and Employers (WISE) study - University of Birmingham
He is currently interested in studying how resources are allocated in real-world organisations and health economies. This covers the role of power, process, evidence, and values, in decision-making.
Hareth has also developed a major stream of work pioneering economic evaluation techniques to better capture the full range of costs and benefits of healthcare interventions. To date he has focused on informal carers, family members, and the development of measures of capability (notably the ICECAP-A). Hareth uses a wide variety of research methods, including qualitative approaches (such as interviews, process tracing, q-methodology, and cognitive interviews) and quantitative approaches (such as preference elicitation and econometrics).
Hareth is also co-investigator in applied projects looking at decision-making in old age and the effectiveness and cost-effectiveness of school-based interventions and pharmacological interventions in mental health.
Hareth’s work has been funded through personal fellowships from the MRC, the NIHR, and the Wellcome Trust, as well as collaborative grants, from the UKRI, MRC, NIHR, Meningitis Research Foundation, STIRF, and British Academy.
