Research Interests

My overall research goal can be broken into two general thematic areas. My first research theme centers on daily stresses, health and well-being in special populations who are generally considered under chronic stress, such as family caregivers of individuals with dementia (IWDs) and women with a history of substantiated childhood sexual abuse.  Two major data sets I utilize are from the Daily Stress and Health (DaSH) project for family caregivers of individuals with dementia, and the Midlife in the United State (MIDUS) study.

I am also interested in applying statistical tools to address research questions that have not been explored with more traditional approaches.  Of particular interest is the application of innovative models for daily outcomes of health and well-being.  This can include daily affective fluctuation and its association with stress; the stabilizing effect of interventions on daily affect; daily intrinsic emotion and emotional diversity as traits and their developmental trajectories over time; fluctuation of daily biomarkers; and biomarker synchrony.
