Technology keeps getting built for clinicians and too often without them. This episode of Signal & Symptoms is about closing that gap. Dr. Junaid Kalia is joined by co-hosts Ed Marx, DR GPT™ Harvey Castro, and now officially on the roster Dr. Isha Mannering, with guest Dr. Ryan Walsh, Chief Medical Information Officer at Memorial Hermann. Ryan calls his path “the Forrest Gump of health IT”: a family physician and residency educator who raised his hand when someone asked “does anyone know about computers?” and ended up double-board-certified as a “human + machine” leader.

The conversation is a working clinician’s field guide to living with AI: what actually excites a CMIO right now, how to de risk AI so you can use it without getting burned, why residents trust an AI summary inside Epic more than an outside source (and why that’s dangerous), and the med-legal reality that governance and law are being outpaced by the technology. Ed lands the episode’s sharpest line that the real leading cause of preventable death in a hospital might not be sepsis, but governance that keeps good tools out. Ryan’s answer isn’t to skip the guardrails: it’s a physician-led clinical AI governance council, piloting carefully, and refusing to throw the baby out with the bathwater “but we do need to test the bathwater.”
