I serve as the Co-Chair for the Diversity, Equity, Inclusion and Anti-Racism Council for the UCSF Benioff Children’s Hospitals. I am the Co-Director of the UCSF Sickle Cell Center of Excellence and I am PI for the Sickle Cell Disease Implementation Consortium in Northern California. I also serve as Regional Director for the Pacific Sickle Cell Regional Collaborative.

Elliott Vichinsky, MD

Professor In Residence
Pediatrics

I am an endowed physician and professor in residence at the University of California San Francisco Benioff Children's Hospital in Oakland, California. For nearly 40 years I have been on forefront of research into better treatments and potential cures for hemoglobinopathies. My directorship of the largest and most comprehensive program for individuals with sickle cell disease and their families in the western United States began in 1978.

Mark Walters, MD

Professor In Residence
Pediatrics

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.
