Mrs Marsha Brierley
Honorary Research Fellow


My interest is in behaviour change interventions, specifically breaking up and reducing sedentary time to improve health and well-being outcomes. I hold a BA in Psychology and a Masters in Sports Performance. My PhD thesis centred on the development of a sedentary workplace intervention for Bedfordshire Police staff using the Behaviour Change Wheel. Having worked in one-on-one health settings with clients over the years, I was motivated to complete a PhD where I could reach more people in real life settings, such as the workplace. Currently, I am the Research Assistant for the RESIT Study (REgulate your SItting Time). I'll be delivering an intervention to help those diagnosed with type 2 diabetes reduce their prolonged sitting with the aim of improving health outcomes.
