Self and Interpersonal Relationships (SIR) Laboratory
My primary research interests are in three interrelated areas: (1) self-esteem, (2) dark
personality features (e.g., narcissism, psychopathy, Machiavellianism, spitefulness), and
(3) interpersonal relationships. Though divergent at times, these substantive areas often
overlap in my research so that much of my work reflects an integration of these topics. In
my research concerning self-esteem, I have focused primarily on the causes and
consequences of fragile high self-esteem as well as the development of the status-signaling
model of self-esteem. My research concerning dark personality features is focused on
identifying potentially aversive aspects of personality and examining their connections
with important life outcomes (e.g., psychological adjustment). Finally, in the area of
interpersonal relationships, I examine how personality features as well as beliefs about the
self and one’s romantic partner influence intimacy, relationship satisfaction, jealousy,
infidelity, and longevity in close relationships.
