My research interests center on social development in childhood, early adolescence, and the college years with a focus on the conceptualization and assessment of relationship competence and relationship outcomes among youth and young adults. This focus includes: (1) studies of the goals children and college students pursue in response to interpersonal conflict and other challenging social tasks; (2) studies of how social relationships influence feelings of loneliness and belonging in elementary school, middle school, and college; (3) research on how maladaptive beliefs about friendship play a role in college students' relationship adjustment. As part of this program of research, my graduate students, and on-campus collaborators in Duke University's Division of Student Affairs have completed a four-year longitudinal study of the connections between social relationships, alcohol use, academic engagement, and feelings of well-being in college. Currently I am engaged in a four-year collaborative study with scholars and academic professionals on four campuses (Davidson, Duke, Furman, and Johnson C. Smith) that focuses on a wide range of psychological processes and outcomes in college student development. This research is supported by funding the The Duke Endowment.
