Koichi Takahashi, MD, PhD is Associate Professor in the Departments of Leukemia and Genomic Medicine at The University of Texas MD Anderson Cancer Center. He received MD degree from Niigata University School of Medicine and PhD degree from Kyoto University School of Medicine, both in Japan. He then did internal medicine residency at Toranomon Hospital, Tokyo, Japan, and Beth Israel Medical Center in New York, followed by hematology and oncology fellowship at MD Anderson Cancer Center in Houston. During the fellowship, he was trained in Dr. Andrew Futreal’s Lab for cancer genomics. He is board certified in Internal Medicine, Hematology, and Medical Oncology. Dr. Takahashi is well known for his research in delineating how selection of pre-existing clonal hematopoiesis under chemotherapy contributes to the development of therapy-related myeloid neoplasms. His laboratory uses state-of-the-art single-cell technologies to understand the mechanism of leukemia development and create strategies for early detection and prevention.
