John Witte
Professor of Epidemiology and Population Health, of Biomedical Data Science and of Genetics
BioDr. Witte joined the Stanford community in July 2021. In addition to serving as Vice Chair and professor in the Department of Epidemiology & Population Health, and as a professor of Biomedical Data Science and, by courtesy, of Genetics, he will also serve as a member of the Stanford Cancer Institute.
Dr. Witte is an internationally recognized expert in genetic epidemiology. His scholarly contributions include deciphering the genetic and environmental basis of prostate cancer and developing widely used methods for the genetic epidemiologic study of disease. His prostate cancer work has used comprehensive genome-wide studies of germline genetics, transcriptomics, and somatic genomics to successfully detect novel variants underlying the risk and aggressiveness of this common disease. A key aspect of this work has been distinguishing genetic factors that may drive increased prostate cancer risk and mortality among African American men. Providing an avenue to determine which men are more likely to be diagnosed with clinically relevant prostate cancer and require additional screening or specific treatment can help reduce disparities in disease prevalence and outcomes across populations. Dr. Witte has also developed novel hierarchical and polygenic risk score modeling for undertaking genetic epidemiology studies. These advances significantly improve our ability to detect disease-causing genes and to translate genetic epidemiologic findings into medical practice.
Dr. Witte has received the Leadership Award from the International Genetic Epidemiology Society (highest award), and the Stephen B. Hulley Award for Excellence in Teaching. His extensive teaching portfolio includes a series of courses in genetic and molecular epidemiology. He has mentored over 50 graduate students and postdoctoral fellows, serves on the executive committees of multiple graduate programs, and has directed a National Institutes of Health funded post-doctoral training program in genetic epidemiology for over 20 years. Recently appointed to the National Cancer Institute Board of Scientific Counselors, Dr. Witte has been continuously supported by the National Institutes of Health. -

Astrid Nicole Zamora
Postdoctoral Scholar, Epidemiology
BioDr. Astrid N. Zamora is a public health researcher and epidemiologist committed to advancing health equity. Her research combines birth cohort data, formative methods (e.g., interviews, ethnography), and behavioral intervention data to investigate health disparities and develop targeted interventions, focusing on Latino/a populations in the U.S. and Mexico. Dr. Zamora’s work explores how environmental exposures, diet, physical activity, and sleep interact to shape psychosocial and cardiometabolic health across the life course. Dr. Zamora is also actively engaged in public health pedagogy, researching equity-focused teaching practices and strategies for fostering inclusive and equitable learning environments for public health students.
After earning her MPH at the UC Berkeley School of Public Health, Dr. Zamora completed her PhD at the University of Michigan School of Public Health. Her NIH/NIEHS-funded dissertation examined the impact of endocrine-disrupting chemical exposure on sleep health and metabolic risk among adolescents and peri-menopausal women in Mexico City, focusing on populations at high risk for health inequities. This work contributed to the growing understanding of how environmental factors affect sleep quality and their implications for long-term metabolic health.
Currently, as a Propel Postdoctoral Scholar at Stanford University School of Medicine, Dr. Zamora is expanding her expertise in randomized controlled trial (RCT) study design and citizen science methodologies. Her work aims to integrate epidemiologic training with community-based research, aligning her scientific agenda with the priorities of the communities she serves. Dr. Zamora’s research seeks to illuminate how diet, sleep, the built environment, and physical activity intersect to influence health outcomes, with the ultimate goal of reducing health disparities and supporting marginalized communities through actionable and equitable public health solutions.
