We often have the evidence to prevent harm long before we actually do something about it, and that delay costs lives. In this episode of the Public Health Insight Podcast, we sit down with a physician and mathematician whose career spans early machine learning research in the 1980s, landmark hypertension trials, and over 150 data monitoring committees. Dr. Davis reflects on the experiences that shaped his thinking and how resistance to change repeats throughout history.
