South Cloisters, University of Exeter, St Luke's Campus, Heavitree Road, Exeter, EX1 2LU, UK


Sian is a Research Fellow in the Exeter HSDR Evidence Synthesis Centre, where she conducts syntheses of evidence about the organisation and delivery of health and social care in the UK. 


  • 2018 PhD Environment and Health, University of York
  • 2013 BSc (Hons) Biology, University of Bristol


Sian joined the Univeristy of Exeter in 2018, working in the European Centre for Environment and Human Health (ECEHH), initially on Greenkeeper, an Innovate UK project with Vivid Economics and Barton Willmore, which developed a toolkit to value the benefits of urban green spaces. She was then an Impact Fellow on the Informing environmental investment for health and wellbeing project, funded by the South West Partnership for Environment and Economic Prosperity (SWEEP).  

Previously, Sian studied BSc Biology at the University of Bristol before moving to the University of York for her PhD. This was part of the ESRC Health of Populations and Ecosystems (HOPE) project and investigated the benefits of freshwater blue space for health and well-being. She analysed UK-wide data on the benefits of blue spaces, as well as using qualitative methods to investigate the dual benefits of an urban river restoration project for the environment and human well-being. After finishing her PhD, she worked on a qualitative systematic review of environmental influences on older people’s travel behaviour.

Research interests

Sian works at the interface between academia, policy and practice with a focus on knowledge translation. She is interested in decision-making at a systems level and the use of evidence in decision-making. Her research has considered this how best to achieve this, in the context of the benefits of the natural environment for human health and wellbeing, and within the health services and public health more widely.
