  • Shady Younis

    Shady Younis

    Instructor, Medicine - Immunology & Rheumatology

    BioShady Younis, PhD is an instructor at the division of Immunology and Rheumatology at Stanford University. He received his PhD in Medical Sciences from Uppsala University in Sweden. He later joined Dr. William Robinson’s Lab at Stanford University as Wallenberg postdoctoral fellow, where he characterized the pathogenic role of cytotoxic CD8+ T cells in rheumatoid arthritis. His current research aimed at elucidating the underlying triggers of pathogenic B cell responses in a spectrum of autoimmune diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS). He uses computational methodologies alongside cutting-edge high-throughput sequencing technologies to characterize the autoreactive B and T cells. The overarching research objective of his research is to unravel the mechanistic roles of Epstein-Barr Virus (EBV) reactivation in activating and transforming autoreactive B cells in the development of autoimmunity.

  • Grace Chen Yu

    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

    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.
