My program of research focuses on developmentally-salient close relationships in adolescence and young adulthood, such as peer relationships, romantic relationships, and sexual relationships. Forming high quality close relationships is an important developmental task for adolescents and young adults. Moreover, these relationships provide a critical context for adolescents and young adults to develop social skills and learn how to navigate conflict. In addition to the publications listed below, recent research in the lab has focused on:  

  • Examining the role of these relationships and experiences in college adjustment
  • Exploring predictors and consequences of conflict in romantic relationships
  • Investigating motivations for dating app use
  • Advancing and propagating best practices for measuring these relationships and experiences
