Kyriaki Myrissa is an associate professor in Nutrition and Health and Exercise Science. Her research focuses on appetite and body weight control, predictors of weight loss and weight loss maintenance, functional foods and wellbeing and research methods. She obtained a BSc in Psychology (2009) from the University of Leeds where she began her research career with a Masters by Research (2011) and continued with completing her PhD (2016) entitled “Putting the person back into weight loss and weight loss maintenance: the role of affect, cognition, behaviour and motivation”.

She has experience working on nutritional projects using advanced quantitative methods in order to investigate effects of functional foods on physiological and psychological wellbeing. Her research interests lie within weight management, obesity, diabetes and any other chronic diseases. She is also interested in the design, implementation and evaluation of complex lifestyle interventions aiming to improve health in adults and children.
