My research examines the developmental origins of how people behave in their closest relationships. I am especially interested in attachment, the psychophysiology of romantic conflict, and to what extent partners' physiological responses to stress and their efforts toward conflict resolution are interdependent. I am also interested in how different kinds of close relationships contribute to social developmental outcomes, including navigating transitions from adolescence to adulthood. My research is guided by the premise that developmental outcomes are probabilistically shaped by experiences in multiple biological and environmental contexts. In other words, we are simultaneously constrained by our pasts and open to change. Additional information can be found at KC's Lab (RADLAB) website.
