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. -

Laura Johnston
Professor of Medicine (Blood and Marrow Transplantation and Cellular Therapy), Emerita
Current Research and Scholarly InterestsClinical research in allogeneic and autologous hematopoietic cell transplantation (HCT), more specifically, allogeneic transplantation and graft versus host disease. Exploring methods of improving prevention and treatment of GVHD as well as the long term follow-up and/or quality of life of affected patients.

Anusha Kalbasi, MD
Associate Professor of Radiation Oncology (Radiation Therapy)
BioDr. Kalbasi is a physician-scientist at the Stanford Cancer Institute. In the clinic, Dr. Kalbasi is a radiation oncologist specializing in the treatment of patients with sarcoma and other solid tumors, with expertise in early phase clinical trials related to immunotherapy, cellular therapy, and radiation therapy.
The Kalbasi laboratory studies cancer immunology, with a focus on understanding—and re-engineering—the molecular conversations that immune cells have with one another and with cancer cells, especially through cytokines. By mapping how these signals are sent, received, and interpreted within immune cells and cancer cells, the lab aims to design next-generation immunotherapies that deliver the right messages at the right time—making cancer-fighting cells more potent, more persistent, and more precise. -

Amer Karam
Clinical Professor, Obstetrics & Gynecology - Gynecologic Oncology
BioDr. Amer Karam is a board-certified, fellowship-trained gynecologic surgeon and clinical professor in the Stanford Medicine Department of Obstetrics & Gynecology, Division of Gynecology Oncology. He specializes in gynecologic oncology, hospice and palliative care, hereditary gynecologic cancers, laparoscopic and robotic gynecologic surgery, and obstetrics and gynecology.
Dr. Karam attended medical school at the American University in Beirut. He completed his internship and residency at the Johns Hopkins Hospital in Baltimore, Maryland, before completing a fellowship in gynecologic oncology at the University of California Los Angeles and a fellowship in breast surgery at the Memorial Sloan-Kettering Cancer Center. Dr. Karam has a vested interest in minimally invasive and robotic surgery with a practice centered on this approach for the treatment of patients with gynecologic malignancy and complicated pelvic surgery. He is currently director of Robotic Surgery and Outreach in the Division of Gynecologic Oncology. -
Maya M. Kasowski
Assistant Professor of Pathology, of Medicine (Pulmonary, Allergy and Critical Care Medicine) and, by courtesy, of Genetics
BioI am a clinical pathologist and assistant professor in the Departments of Medicine, Pathology, and Genetics (by courtesy) at Stanford. I completed my MD-PhD training at Yale University and my residency training and a post-doctoral fellowship in the Department of Genetics at Stanford University. My experiences as a clinical pathologist and genome scientist have made me passionate about applying cutting-edge technologies to primary patient specimens in order to characterize disease pathologies at the molecular level. The core focus of my lab is to study the mechanisms by which genetic variants influence the risk of disease through effects on intermediate molecular phenotypes.
