Dr. Smith is a genetic epidemiologist who investigates the relationship between genetic,
epigenetic, and transcriptomic variation and age-related chronic diseases. She works
with large, multi-ethnic cohort studies to investigates a broad range of traits, including
cardiovascular disease, hypertension, dementia, cognition, and health behaviors. She
studies genetic/epigenetic determinants both as direct risk factors for disease, as
well as the interaction between genetic and non-genetic factors in shaping disease
risk. In particular, she is interested in genetic interaction with social, psychosocial,
and neighborhood determinants of health, especially those that influence socioeconomic
and race/ethnic health disparities.
Dr. Smith is the Associate Director of the Cohort Development working group for U-M Precision Health and the Michigan Genomics Initiative. She is a core faculty member of the Center for Social Epidemiology and Population Health (CSEPH) and is affiliated with the Michigan Center on the Demography of Aging (MiCDA), the Center for Midlife Science, and the Population, Neurodevelopment and Genetics (PNG) Program. She also directs the U-M School of Public Health's Certificate Program in Public Health Genetics.

Genetic Epidemiology, Epigenomics, Aging, Cardiovascular Disease, Cognition, Dementia, Social Determinants of Health
Dr. Smith investigates the impact of genetic variation on cardiovascular disease, cognition, and their risk factors in large, multi-ethnic cohort studies including the Health and Retirement Study (HRS, N=20,000), the Genetic Epidemiology Network of Arteriopathy (GENOA, N=3,000), the Study of Women's Health Across the Nation (SWAN, N=1,100 with genomic data), the Multi-Ethnic Study of Atherosclerosis (MESA, N=6,000), and the Longitudinal Aging Study in India (LASI, N=3,000 with genomic data). As part of this work, she collaborates with several field-leading consortia including the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium and NHLBI's TransOmics for Precision Medicine (TOPMed) initiative. Another component of Dr. Smith's work is in the field of social epigenomics. She is interested in how socioeconomic (education, income, wealth) and neighborhood (neighborhood SES, social environment, land use) factors influence DNA methylation and subsequent risk of cardiovascular disease and dementia in multi-ethnic cohorts. Her work includes the development of high-dimensional mediation methods and their application to social epigenomics.
