Current Research Interests

I am on sabbatical for the 2018-2019 academic year.

I study population health, particularly the association between one's social relationships and health. I am examining different social relationship domains (such as perceived emotional support; how frequently we are in contact with others - social integration) and a broad range of health resources. These include health knowledge, psychological well-being, health risk factors and "hard" health endpoints such as mortality. I hope to better understand how social relationships affect health (i.e., through established risk factors like blood pressure) as well as to characterize patterns of social connections.

I am also interested in health disparities, i.e., identifying modifiable differences in health and well-being across social groups. These group differences are marked by both racial/ethnic boundaries as well as by socioeconomic status (SES; education, income, etc.). I examine disparities utilizing both physical (i.e., chronic disease risk) and psychosocial (well-being, social ties) endpoints.

I also collaborate with colleagues in Health Professions, with the team at NAU's Family Violence Institute and I provide statistical and methodological consulting for Psychological Sciences faculty and students.
