Friendships are among our most valued and cherished relationships in all periods of our lives. My research considers the contributions of friendships and other peer relationships to adjustment and well-being, and my students and I investigate the developmental significance of friendship in childhood, adolescence, and emerging adulthood. What are the concurrent and long-term implications of friendships for the children involved in them? Can friends protect vulnerable children against peer victimization and/or against the negative effects of victimization and bullying? What features and characteristics of friendships are most important? How do characteristics children bring to friendships (e.g., aggression, ADHD) affect their relationships and the outcomes of those relationships?  These are the kinds of questions my students and I address in our research.
