Hao Yan
Postdoctoral Scholar, Bone Marrow Transplantation
BioAs a highly motivated researcher with a passion for conducting basic research that has direct implications for patient care, I have completed my Ph.D. training in physiology in China and pursued postdoctoral training in the United States. My academic training and research experience have provided me with an excellent background in multiple biological disciplines including developmental biology, gerontology, immunology, and pre-clinic research. As a doctoral student with Dr. Guoliang Xia, I focused on mammalian ovary development and aging with the goal of improving the in-vitro fertilization process for cancer patients and women over 40, and aimed to uncover the mechanisms that control the non-renewable oocyte activation and slow down its quantity and quality loss during aging.
During my Ph.D. training, I became interested in immunology research, inspired by my involvement in a project on maternal-fetal immunotolerance. In naturally conceived pregnancies, the fetus is semi-allogeneic to the mother, and the maternal immune system is exposed to foreign HLA antigens from the child. However, the fetus is well-tolerated within a specific time window. As a postdoctoral fellow at Stanford University, I joined the lab of Dr. Robert Negrin, a renowned leader in the bone marrow transplantation (BMT)/GVHD field, to explore immunotolerance-related issues such as graft-versus-host disease and blood malignancies. -

Grace Chen Yu
Clinical Associate Professor, Medicine - Primary Care and Population Health
BioDr. Yu is a modern-day version of the “old-fashioned family doc” who delights in caring for patients from “cradle to grave,” while also promoting the health of her community and developing the future leaders of family medicine. On any particular day, one might find her counseling a long-time smoker on quitting, draining an abscess in clinic, delivering a baby, doing a phone (or sometimes home) visit with one of her elderly patients, lecturing about High-Value Health Care, facilitating a diabetes group visit, singing the praises of coordinated primary care to politicians, discussing end-of-life options with a hospitalized patient, or sharing some of her stories as mother-doctor-teacher with one of her advisees. In 2016, adding one more hat to the mix, Dr. Yu became Program Director of the 24-resident Stanford Health Care - O’Connor Hospital Family Medicine Residency Program. Whereas the old-fashioned family doc was a master at caring for patients at different ages and stages of life, as a modern-day family physician, Dr. Yu is committed to researching ways to do so more effectively and efficiently. She considers it a privilege to be a part of her patients' lives and hopes to help both her patients and her trainees find a path to better health and happiness. To keep herself in great health, Dr. Yu enjoys playing the piano, photography, scuba diving, adventure travel (all the more adventurous with her three children in tow!), and spending time with her family and friends.

Astrid Nicole Zamora
Postdoctoral Scholar, SCRDP/ Heart Disease Prevention
BioDr. Astrid N. Zamora is a public health researcher and epidemiologist. Her work has utilized robust birth cohort data to examine associations between diet and environmental pollutants with sleep and metabolic health outcomes among adolescents and midlife women.
Following her Master of Public Health degree at UC Berkeley School of Public Health, Dr. Zamora completed her PhD at the University of Michigan School of Public Health. As a doctoral trainee at Michigan, her dissertation research, funded by a Research Supplement to Promote Diversity in Health-Related Research from NIH/NIEHS, focused on examining the interplay between exposure to endocrine-disrupting chemicals, sleep, and metabolic health risk among pubertal adolescents and peri-menopausal women from Mexico City.
As a current NHLBI T32 postdoctoral research fellow at Stanford University School of Medicine, Dr. Zamora is receiving training in RCT study design and citizen science methods, learning how to bridge her training in epidemiology with community-based research approaches, thereby ensuring that her research agenda maintains a meaningful connection to the community and its real-world context. The goal of her current research, bolstered by her previous and ongoing training, is to explore the interconnections between diet, the built environment, and physical activity. She is particularly focused on understanding how these factors relate to psychosocial and cardiometabolic health amongst Latinx communities across the life course. -

Tian Yi Zhang, MD, PhD
Assistant Professor of Medicine (Hematology)
BioDr. Zhang is a board-certified hematologist. She is also an assistant professor of hematology at Stanford University School of Medicine. In addition to her medical degree, she holds a PhD in cellular and molecular immunology.
In her clinical practice, she treats patients with all forms of hematological malignancies, offering specialized expertise in acute myeloid leukemia, including therapy-resistant cases. For each patient, she develops a personalized care plan encompassing novel treatment options.
Her research activities include conducting early phase clinical trials, investigator initiated clinical trials (IITs), studying the immune repertoire in patients with myeloid malignancies, and exploring cholesterol metabolic dependencies of acute myeloid leukemia (AML).
She was the recipient of an A.P. Giannini Foundation fellowship award, which supports innovative research. The award helped fund Dr. Zhang’s study of how AML cells interact with other cells in bone marrow. A significant finding confirmed that AML cells secrete a protein that suppresses the production of red blood cells, the same protein that causes inflammation in disorders such as rheumatoid arthritis and Crohn’s disease.
Her many other honors include the National Cancer Institute Career Development (K08) Award, the American Society of Hematology (ASH) Research Training Award for Fellows, Stanford Cancer Institute - American Cancer Society (SCI-ACS) Pilot Grant and Best ASH Abstract Award two years in a row. She also has earned recognition from the National Institutes of Health and American College of Physicians.
She has published her research findings on topics such as advanced therapy for high-risk myelodysplastic syndromes and reversal of bone marrow failure induced by AML. Her work has appeared in Leukemia & Lymphoma, Science Translational Medicine, Cancer Research, the Journal of Clinical Investigation, Journal of Immunology, and elsewhere.
Dr. Zhang is a member of the American Association of Cancer Research and American Society of Hematology. She advises and mentors Stanford medical students, residents and fellows.
