Personal Statement

Patients with congenital blood disorders like hemophilia and thalassemia have experienced a recent renaissance in treatment and clinical trial options. In addition, patients are living well into adulthood with chronic illnesses, and we as providers are witnessing the birth of a new frontier of medicine. I strongly believe in a partnership between patients and physicians. By utilizing this approach, I ensure patients are receiving state-of-the-art treatments and education about their diagnosis. I am excited to utilize my research experience and internal medicine training to help patients and advance the field through early phase clinical trials, quality of life research, and biomarker development.
