  • Astrid Nicole Zamora

    Astrid Nicole Zamora

    Postdoctoral Scholar, Epidemiology

    BioDr. Astrid N. Zamora is a public health researcher and epidemiologist dedicated to advancing health equity. Her research leverages robust birth cohort data, formative research (e.g., interview, ethnography), and behavioral intervention data, primarily among Latino/a populations in the US and Mexico, to better understand health disparities and develop interventions that address the unique health challenges faced by these communities. In addition to this primary focus, Dr. Zamora is actively conducting public health pedagogical research, specifically investigating equity-focused teaching practices and ways to create a more inclusive and equitable learning environment for public health students.

    After completing her MPH at the UC Berkeley School of Public Health, Dr. Zamora pursued her PhD at the University of Michigan School of Public Health. As a doctoral trainee, her dissertation research—funded by an NIH/NIEHS Research Supplement to Promote Diversity in Health-Related Research—examined the impact of endocrine-disrupting chemical exposure on sleep and metabolic health risks among pubertal adolescents and peri-menopausal women in Mexico City, focusing on populations at high risk for health inequities.

    As a Propel Postdoctoral Scholar at Stanford University School of Medicine, Dr. Zamora is furthering her expertise in RCT study design and citizen science methods, bridging her epidemiologic training with community-based research. This training reinforces her commitment to ensuring that her research agenda is closely aligned with the needs and priorities of the communities she serves. Dr. Zamora’s research aims to illuminate how diet, the built environment, and physical activity interact and influence psychosocial and cardiometabolic health across the life course. Through her work, she strives to minimize health disparities and support the health of marginalized communities, creating actionable insights that contribute to a more equitable future for public health.
