The aim of this research group is to support and promote research exploring the role of diet, and lifestyle factors, in mental health and wellbeing.
Our group serves as a collaborative platform for research undertaken in the School of Psychology and School of Life and Health Sciences.
Our research explores the complex connections between diet, nutrition, and lifestyle, and their impacts on both mental and physical health. We focus on areas such as mental health and wellbeing, cognition and brain function, mental health disorders, and the development of prevention and intervention strategies. Our goal is to support health and wellbeing across the lifespan, from pre-conception to old age.
