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/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 Northern California site of the WECARE Study that investigates risk factors for second primary breast cancer;
- 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 racial/ethnic minorities;
- the San Francisco Bay Area Breast Cancer Study, a population-based case-control study in nearly 5,000 Hispanic, African American and non-Hispanic white women that investigated the role of modifiable lifestyle factors and other risk factors;
- 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 racial/ethnic minority populations.
Dr. John is also a founding PI of the LEGACY Girls Study, an on-going 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. -
Tyler Johnson
Clinical Associate Professor, Medicine - Oncology
BioDr. Tyler Johnson is a physician, author, educator, and humanitarian. At the Stanford University School of Medicine, he has held an appointment as a clinical assistant professor for six years. 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 also serves as a leader of the Stanford inpatient oncology services, including supervising the oncology housestaff service. He is responsible, in conjunction with other leaders, for multiple major improvements in the functioning of Stanford hospital.
Dr. Johnson views the practice of medicine largely as an educational endeavor. 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 tirelessly 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 heads the Stanford oncology department’s curricular development and as part of that had developed a novel curricular approach that centers the needs and teaching abilities of oncology fellows. 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. Over the remainder of 2022, this podcast became one of the five most listened-to medical podcasts in the nation, with a growing national and international listenership.
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. -

Joel Neal, MD, PhD
Associate Professor of Medicine (Oncology)
Current Research and Scholarly InterestsI am a thoracic oncologist who cares for patients with non-small cell lung cancer, malignant mesothelioma, and other thoracic malignancies. I design and conduct clinical trials of novel therapies in collaboration with other researchers and pharmaceutical companies. These generally focus on two areas, 1) targeted therapies against particular mutations in cancers (for example EGFR, ALK, ROS1, HER2, KRAS, MET, and others) and 2) the emerging field of immunotherapy in cancer, using anti PD-1/PD-L1 therapies in combination with other agents, and also developing cellular therapies. I also collaborate with other researchers on campus to apply emerging technologies to cancer therapy, for example, circulating tumor DNA detection. Additionally, in my role as the Cancer Center IT Medical Director, I coordinate projects relating to our use of the electronic health record to improve provider efficiency and facilitate patient care.
