In this episode, we explore Antiphospholipid Syndrome (APS) with Dr. Yu (Ray) Zuo, beginning with a clear, clinically grounded explanation before diving into the personal and scientific journey that drew him to this notoriously complex disease. Along the way, Dr. Zuo shares a case that forever changed how he understands APS, then takes us inside his latest Arthritis & Rheumatology study, where machine learning reveals hidden patterns that may reshape how we think about patients and risk. The conversation moves from bedside to bench and back again, tackling what AI can—and can't—do for rheumatology, where APS research is headed next, and what early investigators need to know to build impactful careers.
