BioThe goal of my current research is to use high-resolution imaging techniques to interrogate outstanding questions in cardiac cell biology, with a focus on the signaling pathways that trigger heart muscle contraction. I currently use cryo-electron tomography-based imaging approaches to connect the molecular and cellular scales of biology and accelerate our understanding of human health and disease. https://orcid.org/0000-0003-0737-8383

Joseph Woo, MD, FACS, FACC, FAHA
Norman E. Shumway Professor, Professor of Cardiothoracic Surgery and, by courtesy, of Bioengineering
BioDr. Woo is a board-certified, fellowship-trained cardiothoracic surgeon, cardiovascular surgeon, and transplant surgeon with Stanford Health Care. He is professor and chair of the Stanford Medicine Department of Cardiothoracic Surgery and associate director of the Stanford Cardiovascular Institute. He is also the Norman E. Shumway Professor of Cardiothoracic Surgery and professor, by courtesy, in the Department of Bioengineering.
Dr. Woo is a nationally recognized surgeon, innovator, researcher, and educator in cardiothoracic surgery. He focuses on complex mitral and aortic valve repair, thoracic aortic surgery, heart and lung transplantation, and minimally invasive heart surgery. He was awarded the American Heart Association’s 2021 Clinical Research Prize for developing innovative and minimally invasive surgeries to repair and reconstruct heart valves.
In 2022, Dr. Woo and his team at Stanford Health Care performed the first beating-heart transplant from a donation after circulatory death (DCD) donor and organ perfusion system. Keeping a donor heart pumping while it’s transported to the recipient and then implanting the heart while it’s beating minimizes organ damage. This groundbreaking new procedure is expected to increase the number of hearts available for transplant while improving health outcomes.
As a physician-scientist, Dr. Woo has served as principal investigator on multiple studies funded by National Institutes of Health (NIH) grants. One explored an innovative therapy to stimulate vascular (blood-carrying) stem cells in the bone marrow and direct them to the heart to grow new blood vessels and improve blood flow to damaged heart muscle.
Dr. Woo has also been the primary investigator for clinical trials involving the administration of stem cells during coronary artery bypass grafting (CABG) and left ventricular assist device (LVAD) implantation. In addition, Dr. Woo has served as primary investigator for multiple clinical device trials. He has filed for and holds patents for several heart-related medical devices and surgical techniques.
Dr. Woo has co-authored more than 510 articles in peer-reviewed journals and has served as a reviewer for many of them, including the Annals of Thoracic Surgery, Journal of Thoracic and Cardiovascular Surgery, and Circulation. He has also presented his research and performed live surgery demonstrations both nationally and internationally.
Dr. Woo serves as president-elect of the American Association for Thoracic Surgery (AATS) and past president of the AATS Cardiac Surgery Biology Club. He is a fellow of the American College of Surgeons, American College of Cardiology, and American Heart Association. He is a member of many other professional societies, including the World Society of Cardiovascular and Thoracic Surgeons and International Society for Heart Research. He also serves on the leadership committee of the American Heart Association’s Council on Cardiovascular Surgery and Anesthesia. -
Fan Yang
Associate Professor of Orthopaedic Surgery and of Bioengineering
On Leave from 03/01/2026 To 03/31/2026Current Research and Scholarly InterestsOur lab’s mission is to develop therapies for regenerating human tissues lost due to diseases or aging, and to build tissue engineered 3D models for understanding disease progression and informing drug discovery. We invent biomaterials and engineering tools to elucidate and modulate biology, and also use biology to inform materials and engineering design. Our work is highly interdisciplinary, and is driven by unmet clinical needs or key gaps in biology.

Yunzhi Peter Yang
Professor of Orthopaedic Surgery and, by courtesy, of Materials Science and Engineering and of Bioengineering
On Partial Leave from 12/01/2025 To 05/31/2026Current Research and Scholarly InterestsThe Yang Lab focuses on next-generation solutions at the intersection of 3D printing, regenerative medicine, modular tissue engineering, biomaterials, and medical device innovation. Our research focuses on engineering dynamic, biomimetic microenvironments that promote cell growth, tissue regeneration, and functional restoration. We develop transformative technologies to treat a broad spectrum of musculoskeletal conditions—including multi-tissue healing challenges and complex traumatic injuries.
