Mark Walters, MD

The over-arching goal of my research career has been to develop and expand curative therapies for hemoglobin disorders in particular and non-malignant hematopoietic disorders more broadly. I have focused on genome editing approaches most recently, which rely upon modification of autologous hematopoietic cells to elicit a curative effect. In collaboration with colleagues at UC Berkeley, BCHO and UCLA, we are pursuing genomic editing of the sickle mutation in hematopoietic stem cells using the CRSPR/Cas9 ribonucleoprotein system. I have a long track record of experience in cellular therapies for pediatric acquired and hereditary conditions and in bone marrow transplantation.
