My research concerns the interplay between the individual and relational self in terms of everyday processes and individual differences. For example, how does nostalgia arise in interpersonal interactions? How do individual differences in self-concept (e.g., narcissism) moderate relational processes? Conversely, how do individual differences in relationship orientation (e.g., attachment anxiety and avoidance) moderate the regulation of the self?

Current work focuses on: the operation of, and individual differences in, self-evaluation motives - particularly the motives to self-enhance and self-improve; intrapersonal and interpersonal functioning among individuals with high versus low narcissism; the definition, functions, and experience of nostalgia; and adult attachment and close relationships, including sexual functioning and self-views and interpersonal closeness motivation.
