- Profile
-
I am a Research Fellow in the Sheffield Addictions Research Group, funded by the Wellcome Trust. My background is in Psychology, and my research has largely focused on understanding the cognitive mechanisms that underlie behaviour change and recovery from addiction, with applications to alcohol, nicotine, and cannabis use. I have been at the University of Sheffield since 2018, joining the School of Medicine and Population Health in 2025.
I recently secured funding to develop a new computational model to explore how environmental factors influence people’s attempts to reduce their alcohol consumption, and to use this model to appraise novel alcohol policies. The project combines two computational approaches: drift-diffusion models, which capture immediate, moment-to-moment decision-making processes, and agent-based models, which simulate how individual decisions aggregate into population-level trends over time. While my project focuses on alcohol, the modelling infrastructure I develop will be adaptable to other public health challenges, including diet, vaping, and gambling.
