My research interests broadly fit into the areas of Health Psychology, Psychobiology and Applied Mental Health research. My PhD focused on the effects of individual differences (i.e., Type D personality) on stress reactivity and associated health outcomes and my post-doc work involved the development of interventions for somatic symptom disorders.

More recently the focus of my research has involved the exploration of factors underpinning the development of mental health issues in students, particularly with regards to previous trauma and sleep health. I am also interested in the bidirectional relationship between poor sleep and mental health disorders as well as the use of creative and compassionate interventions for improving psychological well-being.
