Faculty Profile
Jennifer A Smith, PhD, MPH
- Associate Professor of Epidemiology
- Research Associate Professor, Survey Research
- Director, Certificate in Public Health Genetics
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 Assistant 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.

Research Projects:
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.
