Research Interests: My research focuses on a central question: How does our social world influence our health? 

• How interpersonal processes influence the psychological and physical wellbeing of both individuals and dyads over time, as well as the potential bidirectional nature of this relationship.
• Utilizing advanced quantitative methods, including multilevel modeling and Bayesian statistics.
• Examining autonomic physiological linkage (i.e., any form of statistical interdependence between the physiological signals of interacting partners) among romantic partners and strangers - with an emphasis on understanding mechanisms, context-dependency, and non-linear modeling of this phenomenon.
• Translating findings from relationship science to develop new interventions that promote mental, physical, and relational wellbeing among couples and families. 
• Working with families and couples using evidence-based practices to promote healthy relationships.
