Applications are invited for a self-funded, 3 year full-time or 6 year part-time PhD project, to commence in October or February.

This 3-year full-time or 6-year part-time, self-funded PhD will be based in the Faculty of Business and Law, and will be supervised by Dr Daniel Nunan and Dr Giampaolo Viglia.

The objectives of the project are:

  • to understand approaches to risk communication and influences on risk perception when mediated through social media
  • to understand the role of social influence in determining perceptions of risk
  • to identify recommendations for practical communication approaches that leverage the targeting and segmentation techniques available on digital channels to enable the effective communication of complex risks

This PhD project aims to explore techniques that enable the effective communication of complex risks to the public in contexts that improve health and reduce risks of harm.

Working within our Marketing & Society research grouping this project builds on a research stream that seeks to broaden the impact of marketing research and consider the role of marketing activities amongst non-commercial stakeholders.

This project will address a research theme relating to the application of marketing techniques to improve health and wellbeing. The contextual focus of this project will be supported by working with a high-profile public sector organisation developing practical solutions to real-world problems.

Research has long-established that public perceptions of risk differ from expert evaluations. Understanding how individuals perceived risk is therefore key to effectively communicating risk in a way that will encourage appropriate behavioural responses.

This project looks at the way in which risks, particularly complex risks, related to health and safety are perceived and understood by individuals when communicated through digital channels.

The growing use of digital channels (particularly social media) as a communication medium also challenges existing approaches to risk communication. While social media provides the opportunity for more targeted communications and can potentially increase reach into vulnerable or hard-to-reach groups, the role of social influence can make communicating risks more difficult.
