My research is devoted to improving our understanding of what interventions are effective in tackling complex psychological, social, and health problems. I have looked at a range of issues, and my projects aim to integrate the use of several high-quality methodological approaches, many of which have not been traditionally applied in the social sciences.
I am also Affiliate Professor at the Department of Family Studies, University of Malta, and a member of the Cross-Whitehall Trial Advice Panel within the Cabinet Office, UK Government.
