My research addresses key questions in global mental health, particularly how social and economic disadvantage both shapes and is shaped by mental health across diverse settings.

I work across three interconnected areas: the social and economic consequences of mental health problems across the life course; the development and evaluation of interventions to improve access to care and support; and the advancement of equity through stigma reduction and the translation of research to policy and practice.

Recent and current projects include using British birth cohort data to estimate the long-term social and economic costs of childhood mental health problems; developing and evaluating interventions that combine mental health support with anti-poverty programmes (CHANCES-6, ALIVE, Mentalkit); leading the global attitudes surveys for the World Alzheimer Reports (2019 and 2024) and evaluating England's Time to Change anti-stigma campaign, which the Royal Society for Public Health recognised as one of the top 20 public health achievements of the 21st century.

I have led research projects with more than £25 million in grant funding as PI or Co-PI since 2015. I serve on the International Advisory Board of Alzheimer's Disease International, the Scientific Advisory Council of Bring Change to Mind, and the Medical Research Council Global Health Faculty of Experts.
