People

Thea Tlsty, PhD studies the identity and role of cancer stem cells in the development and progression of breast cancer. She also has a research program on the characterization of genomic instability in cancer initiation and progression.

Erik Ullian, PhD studies the cell extrinsic and intrinsic mechanisms that regulate synapse number and function, particularly the role of glial cells in regulating neuronal synapse formation and function.

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.

Dan Wagner, PhD studies the molecular mechanisms of tissue patterning and error correction in vertebrate embryos using high-throughput single-cell profiling, in vivo imaging, and functional genomics. Visit the Wagner lab website.

Mark Walters, MD develops and expands curative therapies for hemoglobin disorders and non-malignant hematopoietic disorders. He pursues genomic editing of the sickle mutation in hematopoietic stem cells using the CRISPR/Cas9 ribonucleoprotein system.

Rong Wang, PhD studies cell signaling in mammalian angiogenesis and arterial venous differentiation in embryos, ischemia, stroke and cancer.

Bruce Wang, MD studies the cellular and molecular mechanisms that regulate liver development, homeostasis and regeneration.

Valerie Weaver, PhD focuses on several areas of human embryonic stem cell 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.

Holger Willenbring, MD explores the way liver cells differentiate and regenerate with the goal of correcting liver diseases using cells derived from stem cells or by reprogramming hematopoietic cells.
