Personal profile

Research Interests

I am interested in the biopsychological aspects of human eating behaviour, and interventions aimed at altering food intake and food selection to improve health. I am particularly interested in psychopharmacological, cognitive, and social influences on human eating behaviour.


I graduated with a degree in Psychology from Swansea University in 2008, after which I spent time as an Assistant Clinical Psychologist. In 2009 I undertook a Masters at the University of Birmingham and then a PhD in 2010. My PhD experimental work was undertaken both at Birmingham and at the University of Oxford in collaboration with my industrial sponsor P1vital. Between 2013-2016 I worked on a social norms approach to healthy eating as an ESRC Research Fellow at University of Birmingham. I am presently a Lecturer in Psychology at Aston University and an Honorary Research Fellow at University of Birmingham.
