His research has shown clear links between racism and poorer health outcomes. The author of over 400 scientific papers, David has been honored for his contributions to the field. He is a member of the prestigious National Academy of Medicine and was honored with an award from the Association of American Medical Colleges for his lifetime of work on health equity.
