Andy Jones is an associate in research and evaluation at C3.

Andy has over 30 years’ experience as an academic. He graduated with a degree and PhD in environmental sciences and undertook research in that field for many years, becoming increasingly interested in the role of the environment as a determinant of population health. In 2012 Andy transitioned to working full-time in the field of public health by joining Norwich Medical School at the University of East Anglia as a Professor of Public Health where he led the Department of Public Health and Health Services Research. More recently he has worked in the public health team at Norfolk County Council, acting as an expert advisor in the use of research and evidence in public health delivery.

Andy has strong interests in the evaluation of health-related interventions and has partnered with a wide variety of organisations to support evaluation work, including local and central government, the third sector, health services, and academia. He uses more formal study designs such as randomised controlled trials, but he has a particular passion for taking a pragmatic approach to evaluation, which involves the application of mixed methods to fit evaluation around programme delivery to ensure high-quality evidence is produced on how programmes work in real-world settings.

Andy’s role:

At C3, Andy’s work involves the identification and delivery of research and evaluation opportunities to support the activities of the organisation.

How Andy practices what he preaches:

Andy is a keen runner and cyclist and uses his bike rather than driving when possible. He used to run competitively and came 155th out of 35,000 finishers in the 2008 London marathon. Deciding he was unlikely to better that, he now focusses on recreational running from his home in the Norfolk countryside. He finds the scenery moves past him more slowly than it used to, but the benefits to his mental and physical health from running are just as strong!
