My research focuses broadly on close relationships, sexual wellbeing and couples. Specifically, I am interested in understanding interpersonal predictors of wellbeing among individuals in relationships and couples, particularly those who may be coping with challenges such as sexual difficulty (e.g., orgasmic disorder) or infidelity. I am also interested in the experience of extradyadic attraction among those in romantic relationships.
I welcome enquiries from clinical and experimental graduate students who may be interested in pursuing research in these areas.
Considering graduate supervision for 2025 and 2026 intake.
