I am a clinician and clinician scientist with an interest in translating potentially curative therapies to people with genetic diseases, particularly sickle cell disease and thalassemia. These therapies include standard and newer stem cell transplants as well as gene therapies. I performed the first gene therapy treatment for sickle cell disease at the Texas Medical Center in Houston in 2020 (via clinical trial) and am excited to translate more therapies at Stanford for sickle cell disease, thalassemia, and other rare genetic diseases. Additionally, I have an interest in understanding the long-term effects of stem cell therapies and participate as a member of STAR (Sickle Cell Transplant Advocacy and Research Alliance) to understand such. For all stem cell-based therapies, I strive to safely reduce toxicity related to the treatments whenever possible. Finally, I have a passion for global health and recognize disparities in health care access both within the US and abroad. Outside of North Carolina, Texas, and California, I have spent time learning and practicing medicine in Africa, India, and South and Central America witnessing the global effects of pediatric hematologic diseases. As a fierce advocate for members of the sickle cell community I strive to provide exceptional medical care considering the various complexities of this disease and safely expand access to disease modifying and corrective therapies to those interested and in need.
