I am interested in developing new ways to gather and analyze data on social interactions among family members and other connected individuals. Human beings develop through interacting with family members, peers, friends, and others. The characteristics of these social interactions have important implications on various aspects of individual well-being. My research involves using new technologies (e.g., smartphones, wearable devices) to collect real-time data on the physiological and emotional responses of individuals who are interacting with others. New technology allows us to do this in a non-intrusive manner.
With this data, we develop innovative statistical methods to model human social interactions. Some examples include examining synchrony in stress hormones in married couples on a day-to-day basis, and investigating physiological interactions between therapists and autistic children during psychotherapy.
