My research focuses on social and emotional development within the context of the family. My research program is guided by 3 major and interconnected themes: 1) the development of emotion and its regulation (e.g., affect, cardiac physiology, and regulatory strategies), 2) the impact of context (e.g., early parent-child relationships and the marital relationship), and 3) individual differences in child temperament. I am particularly interested in the role of the father in his child’s development, such as how father-infant dynamics are similar to or differ from mother-infant dynamics. I use longitudinal designs and multiple methods (e.g., experimenter-report, parent-report, physiological methods, observational coding, etc.) to answer my research questions.
