Today we discuss the most important element of our lives: our health. We do so by diving into personalized medicine, or more specifically, personalized (N-of-1) trials  – clinical trials in which a single patient is the entire trial. For this episode, we invited two editors of Harvard Data Science Review’s special issue on N-of-1 trials and data science to help us examine all aspects of these clinical trials designed for a population of one person. Our guests: Dr. Karina Davidson, Senior Vice President of Research and Dean of Academic Affairs at Northwell Health Ken Cheung, Professor of Biostatistics at Mailman School of Public Health at Columbia University
