Overview
I am a professor in the School of Social Sciences, and a statistician and epidemiologist by training. My research is focused mainly 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. Please see our website ylab.wales for more details.
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.

Research
@ylabwales we conducted research on public service innovation, including through several of our programmes, including:
- Innovate to Save
- Health, Arts, Research, People (HARP)
- Innovative Future Services (Infuse)
- Cardiff Capital Region Challenge Fund
The primary evaluation methodologies I have applied in global health have been cluster randomised trials and stepped wedge trials, always in interdisciplinary teams. I lived and worked in Johannesburg for seven years and I have also worked on projects in Peru, Burkina Faso, India, China, Zimbabwe and Zambia.

Supervisions
I am interested in supervising PhD and Professional Doctorate students in the areas of public health evaluations, epidemiology, quantitative public health, public services innovation and social innovation.
Current supervision
Becky Parish
Research student
Past projects
- Kavi Velen's PhD on "GOOD to GREAT: Strategies to improve the detection of TB amongst household contacts in South Africa"
- Cara O'Connor's PhD on "Mobile Phone Adherence Support for HIV Patients in Manila, Philippines"
- Becky Parish's professional doctorate on "Informed Choice or Informed Voice? A consideration of the impact of proposed NHS service developments on divided communities"
I was a statistical advisor for six PhD students at LSHTM, a role similar to that of co-supervisor.
