Research Interests: 

My research focuses on the

• Social contexts of health
• How interpersonal processes relate to psychological and physical wellbeing of both individuals and couples over time

Research Skills:

• Utilizing advanced quantitative methods, including multilevel modeling and Bayesian statistics.
• Modeling 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 the non-linear dynamics of this phenomenon.
• Translating findings from relationship science to develop new interventions that promote mental, physical, and relational wellbeing among couples and families.
