<p>Dr. Jason Chien, MD, MS, is the Chief Medical Officer of Mozart Therapeutics, where he leads clinical development of a first-in-class pipeline targeting autoimmune diseases, including type 1 diabetes and celiac disease. He trained in internal medicine, infectious diseases, and pulmonary and critical care medicine before building an NIH-funded research program at the University of Washington and Fred Hutchinson Cancer Research Center. He then spent nearly eight years at Gilead Sciences and five years at Johnson &amp; Johnson, leading global R&amp;D strategy, before returning to his scientific roots in biotech.</p><p>In this episode, Dr. Chien walks us through a career he describes as unfolding in decades — each phase building on the last. We hear what pulled him out of academia and into industry, why learning to crunch his own numbers changed everything, and what it feels like to now be responsible for putting a brand new mechanism of action into human beings for the very first time.</p><p>We close with Dr. Chien's take on leadership, the MD/MBA question, and what he would do differently looking back. His advice to students: stay curious, watch where AI is taking the field, and resist investing in any one thing that makes you lose sight of where you actually want to go.</p>
