Faculty V-Y


  • Ron Vale, PhD studies how cells move organelles, proteins, chromosomes and mRNAs within their cytoplasm.
  • Karin Vargervik, DDS is the director of the UCSF Center for Craniofacial Anomalies and has a special interest in the etiology and development, as well as therapeutic modalities, of cleft palate and lip.
  • Eric Verdin, MD studies stem cell pluripotency and self-renewal.
  • Saul Villeda, PhD studies how molecular immune-related changes in old blood impair stem cell function and cognitive processes in the brain during aging, and conversely how young blood can reverse these impairments.
  • Thiennu Vu, MD, PhD is interested in the role of the vasculature during organogenesis.


  • Bruce Wang, MD studies the cellular and molecular mechanisms that regulate liver development, homeostasis and regeneration.
  • Rong Wang, PhD studies cell signaling in mammalian angiogenesis and arterial venous differentiation in embryos, ischemia, stroke and cancer.
  • Valerie Weaver, PhD focuses on several areas of human embryonic stem cell (hESC) development and architecture.
  • William Weiss, MD, PhD is interested in developing and characterizing mouse models that faithfully recapitulate the biology and genetics of human tumors of the nervous system.
  • Zena Werb, PhD studies the role of proteases in the interaction of tissues with the extracellular matrix, thereby focusing on bone formation, fat development, epithelial-mesenchymal interactions in mammary gland development, and cancer progression.
  • Holger Willenbring, MD is exploring the way liver cells differentiate and regenerate, with the goal to correct liver diseases with cells derived from stem cells or from reprogramming of hematopoietic cells.


  • Keith Yamamoto, PhD is interested in mechanisms by which gene transcription is regulated in different cell types and physiological (or pathological) settings. He studies the activity of the intracellular receptors (IRs), including receptors for glucocorticoids (GR), androgens (AR) and thyroid hormone (TR) in signal transduction and trancsriptional control.
  • Shinya Yamanaka, PhD studies stem-cell pluripotency.
  • Yerem Yeghiazarians, MD an adult interventional cardiologist, studies embryonic and adult stem cells introduced into rodent and swine hearts after injury and is involved in numerous clinical trials using interventional catheter approaches.
  • Ann Zovein, MD Diversification of vascular lineages
