In this episode of Run the List, Blake Smith (host) talks with Dr. David Steensma, a hematologist/oncologist at Dana-Farber Cancer Institute, about his career path, the changing landscape of the field, and how to immerse oneself in new disease indications within an already-established division of medicine. They talk about Dr. Steensma’s impressive writing career, scientific and clinical research, and his budding interest in clonal hematopoiesis. The episode closes with a retrospective discussion of hematology/oncology, how the field has changed over time, and a look to the future.
