Professor
Overview
I am a professor in the School of Social Sciences and the Centre for the Development, Evaluation, Complexity and Implementation in Public Health Improvement (DECIPHer). I serve on DECIPHer's Executive Management team and I am a co-investigator on our HCRW Sustainability Funding 2025-30 (£2.9m), and lead on our International work. I am also a co-investigator on our Centre for Adult Social Care (HCRW funded, £3m), and the Local Policy and Innovation Partnership for Rural Wales (ESRC funded, £5m). My research is focused on better understanding public health challenges and designing and evaluating relevant interventions.
From March 2018 to September 2023 I was the director of Cardiff University's Y Lab - the Public Services Innovation Lab for Wales. At Y Lab we supported and promoted experimentation and innovation in public services in Wales, and conducted research on the hows and whys of public services innovation. We brought in £12m of funding, including £10m to Cardiff University. We were honoured to win Cardiff University’s Celebrating Excellence Award in the Excellence in Innovation and Enterprise category in 2022.
Prior to this, I worked as a statistician and epidemiologist at the London School of Hygiene & Tropical Medicine for 12 years. I conducted research in global health, focusing on pragmatic evaluations of health system innovations across a range of disease areas and geographies. I lived in Johannesburg for seven years.
