William Matsui is a Professor of Oncology, Director of the Hematologic Malignancy Program, Associate Chair of Research, and the Deputy Director of the LiveSTRONG Cancer Institutes at the Dell Medical School and the University of Texas at Austin. He also serves as the interim Vice Dean of Research for Dell Med. Dr. Matsui's research has focused on understanding the intersection between cancer, stem cell, and developmental biology. His laboratory first identified unique populations of cancer cells with stem cell properties in multiple myeloma and found that several pathways regulating normal stem cells, including those involved in embryonic development, are abnormally activated in cancer stem cells. Importantly, these basic research studies have simultaneously been translationally relevant and served as the basis for over a dozen novel clinical trials.
