David Thomas John
Undergraduate, Vice Provost for Undergraduate Education
BioHi! My name is David John from San Diego, California. I am an Economics major (hopefully), and I am especially interested in Economics in relation to History. During High school, I researched the economic and political impact of California's Alien Land Laws on the different Asian ethnic groups that were primarily targeted by these laws, as I felt that this was a dark and impactful period in the History of California that not many of my peers or the general public are aware of. In my free time, I love to hang out with my friends, try new food, and play lacrosse.

Esther M. John
Professor (Research) of Epidemiology and Population Health and of Medicine (Oncology)
Current Research and Scholarly InterestsDr. John has extensive expertise in conducting population-based epidemiologic studies and has led as Principal Investigator multiple large-scale studies, including multi-center studies with a study site in the San Francisco Bay Area with its diverse population. Many of her studies and collaborations investigated cancer health disparities. Her research has focused on the role of modifiable lifestyle factors (e.g., body size, physical activity, diet), hormonal factors, early-life exposures, genetic variants, and gene-environment interactions; differences in risk factors by race and ethnicity, breast cancer subtypes, and prostate cancer subtypes; risk factors for familial breast cancer and second primary breast cancer, as well as prognostic factors related to survival disparities.
As Principal Investigator, Dr. John has led a number of studies conducted in the San Francisco Bay Area, including:
- the Northern California site of the Breast Cancer Family Registry, an on-going prospective multi-generational cohort of over 13,000 families established in 1995 at six international sites;
- the San Francisco Bay Area Breast Cancer Study, a population-based case-control study in nearly 5,000 African American, Hispanic, and non-Hispanic White women that investigated the role of modifiable lifestyle factors and other risk factors;
- the California site of the Breast Cancer Health Disparities Study that investigated genetic variability and breast cancer risk and survival in Hispanic and non-Hispanic White populations in the context of genetic admixture;
- the Breast Cancer Etiology in Minorities (BEM) Study, a pooled analysis of risk factors for breast cancer subtypes in minoritized racial and ethnic populations;
- the Northern California site of the WECARE Study that investigates risk factors for second primary contralateral breast cancer;
- the Second Primary Breast Cancer Disparities Study, a pooled analysis of risk factors for contralateral and ipsilateral second primary breast cancer in a diverse population;
- the San Francisco Bay Area Prostate Cancer Study, a population-based case-control study of lifestyle and genetic risk factors for advanced and localized disease.
These studies collected and pooled extensive data and biospecimens and continue to support numerous ancillary studies, collaborations and international consortia and have contributed to a better understanding of cancer risk and survival in minoritized racial and ethnic populations.
Dr. John is a founding PI of the LEGACY Girls Study, a prospective cohort established in 2011 that investigates early life exposures in relation to pubertal development outcomes, breast tissue characteristics, and behavioral and psychosocial outcomes in the context of having a family history or breast cancer.
In 2023, Dr. John joined the Stanford investigator team of the MOSAAIC (The Multiethnic Observational Study in American Asian and Pacific Islander Communities) Study, a five-center study to improve health of American Asian, Native Hawaiian, and Pacific Islander populations. -

Tyler Johnson
Clinical Associate Professor, Medicine - Oncology
BioDr. Tyler Johnson--a clinical associate professor of medicine and oncology at Stanford University Medical School--is a physician, author, educator, and humanitarian. A medical oncologist, Dr. Johnson sees patients with all types of gastrointestinal malignancies and particularly focuses on patients with neuroendocrine tumors, colon cancer, and pancreas cancer.
Dr. Johnson served for many years as a leader of the Stanford Hospital in-patient oncology services and helped launch the hospital's first direct care inpatient service, med 12. He is also responsible for helping respond to the surge of patients that came with the pandemic and its aftermath.
Dr. Johnson views the practice of medicine largely as an educational endeavor. He directs the Stanford University Hematology/Oncology Fellowship Program and spends significant time teaching trainees at levels. To that end, for many years he has taught medical students, residents, and fellows—including hosting them as temporary and longer-term apprentices in his oncology clinic and working with them on the inpatient housestaff oncology service. He emphasizes diversity and inclusion in his mentoring efforts and has worked to promote the professional development of medical trainees across the training spectrum--from undergraduates to oncology fellows.
The winner of multiple Stanford Medicine teaching awards, Dr. Johnson has established himself as a regional and increasingly as a national leader and innovator in the education of oncology fellows, including by developing novel teaching methods that have been presented across the country, including at national meetings. He also works as one of the principal faculty members of the Stanford Educators-4-CARE program.
Dr. Johnson and his co-host, Henry Bair, became concerned about the loss of a shared sense of meaning in the medical profession and, together, have taught multiple classes in the Medical School and, in the spring of 2022, founded The Doctor's Art podcast. Since then, the podcast has become one of the most listened to medical podcasts in the world and has won multiple national awards, making it one of the most lauded and most popular medical podcasts.
Finally, Dr. Johnson is an author with a growing reputation for insightful analysis of the intersection of medicine, ethics, and spirituality. His writings has been featured by Religion News Service, the Salt Lake Tribune, BYU Studies, Dialogue, and The San Jose Mercury News, where he is a regular contributor. He serves on the editorial boards of both BYU Studies and Wayfare and has written extensively on modernity loss of faith and meaning and the role of spirituality in constructing a purposeful and fulfilling life. -
