Irving L. Weissman, M.D., is the Director of the Stanford Institute for Stem Cell Biology and Regenerative Medicine and Director of the Stanford Comprehensive Cancer Center.
His research encompasses the biology and evolution of stem cells and progenitor cells, mainly blood-forming and brain-forming. He is also engaged in isolating and characterizing the rare cancer and leukemia stem cells as the only dangerous cells in these malignancies, especially with human cancers. Finally, he has a long-term research interest in the phylogeny and developmental biology of the cells that make up the blood-forming and immune systems.
Professor Weissman is a member of the National Academy of Sciences, the Institute of Medicine at the National Academy, and the American Association of Arts and Sciences.
