Paula Pietromonaco is a social psychologist who studies how people think, feel, and behave in the context of their closest relationships. Her particular interest lies in how couple members influence each other’s ability to manage their emotions, and how these relationship processes are connected to emotional and physical health over time. She is currently funded by a grant from the National Cancer Institute for a longitudinal study that examines how newlywed spouses’ expectations and beliefs about relationships, together with their physiological stress reactions and behavior patterns when discussing disagreements, predict later risks for depression and anxiety. This research will shed light on basic processes through which spouses may influence each other’s health and lay the foundation for examining these processes in couples in which one partner is coping with cancer risk or diagnosis. She is a leader in the study of close relationships and is known for her use of multiple methods of investigation, combining direct observation of dating and married couples, daily event sampling methods, survey, and laboratory experiments. In addition to publishing in and serving on the editorial boards of the most highly regarded journals in social and personality psychology, she has served as an Associate Editor for the Journal of Personality and Social Psychology and for Personality and Social Psychology Bulletin, and she is currently a Deputy Editor for Psychological Science.
