Chad S. Weldy, M.D., Ph.D.
Instructor, Medicine - Cardiovascular Medicine
Current Research and Scholarly InterestsAs a physician-scientist I work to understand the genetic basis of cardiovascular disease and the transcriptional and epigenomic mechanisms of atherosclerosis. My work is focused across four main areas of cardiovascular genetics and mechanisms of coronary artery disease and smooth muscle biology:
1.Vascular smooth muscle specific ADAR1 mediated RNA editing of double stranded RNA and activation of the double stranded RNA receptor MDA5 in coronary artery disease and vascular calcification
2.Defining on single cell resolution the cellular and epigenomic features of human vascular disease across vascular beds of differing embryonic origin
3.CRISPRi screening with targeted perturb seq (TAPseq) to identify novel CAD genes in human coronary artery smooth muscle cells
4.Investigation of the epigenetic and molecular basis of coronary artery disease and smooth muscle cell transition in mice with conditional smooth muscle genetic deletion of CAD genes Pdgfd and Sox9
My work is focused on discovery of causal mechanisms of disease through leveraging human genetics with sophisticated molecular biology, single cell sequencing technologies, and mouse models of disease. This work attempts to apply multiple scientific research arms to ultimately lead to novel understandings of vascular disease and discover important new therapeutic approaches for drug discovery.

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.

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.
