On this first leg of the Summer Tour, I sit down with my friend Darryl Davis. Darryl is a clinician-scientist and cardiac electrophysiologist in the Division of Cardiology at the University of Ottawa Heart Institute. We discuss the formative influence of French language immersion, a high school biology course, and his journey to cardiac electrophysiology. We also discuss his clinical efforts, research activities, and now a start-up company (Rhythm Therapeutics) using a novel therapeutic.
