Areas of expertise/research interests

  • romantic relationship processes, commitment and cohabitation
  • evaluation of relationship education programs
  • impact of parents' relationships on children

Current research and projects

My research is on romantic relationship development and functioning, and the related implications for children and adults. Current research projects and collaborations include 1) basic science studies on commitment, cohabitation, aggression, infidelity, family background, relationship processes and psychopathology, military families, and adolescent and child adjustment as well as 2) studies on the effectiveness of preventive relationship interventions for couples and individuals (including gene-environment interactions). I am the PI, Co-I, evaluator or consultant on several foundation or federally-funded projects. As examples, one project is testing the effectiveness of hospital-based relationship education delivered to pregnant women (funded by ACF; see and another is on measuring and modeling early relationship development (funded by NICHD). A particular area of interest my applied work is the prevention of intimate partner violence through community-based relationship education.
