ResearchGate profile

I am a senior lecturer in Psychology at Liverpool Hope University. I completed a BSc (Hons) degree at Keele University before undertaking an MSc in Psychological research methods and PhD at the University of Bristol (ESRC funded scholarship). My thesis looked at the role of interoception (the ability to detect internal bodily signals) and dietary learning on eating behaviour. I subsequently undertook a one-year industry funded post-doctoral post at the University of Liverpool before beginning lecturing posts at the University of Liverpool, then the University of Salford and now Liverpool Hope.

My research focuses on food intake and factors driving weight gain. I am particularly interested in how food insecurity (not knowing if you will have enough food to eat at your next meal) might place individuals at risk of weight gain and associated Psychological and Biological mechanisms.  I am also interested in the role of environmental factors on food intake (larger portion sizes, meal variety, distraction whilst eating) and how we can promote more sustainable diets. I have previously been awarded funding by the British Psychological Society, British Science Institute and I currently run a British Academy / Leverhulme project looking at the effects of food insecurity on levels of physical activity.

I am a member of the Association for Project Management (APM), a chartered Member of the British Psychological Society (BPS),and a fellow of the Higher Education Academy 

My current teaching responsibilities are leading the level I core 2 block of teaching. I also lead the third-year theory lectures on emotions and motivations, co-lead the first year history of Psychology lecture series and teach some advanced statistics (Structural Equation Modelling) on our MSc courses.
