This week on the Good Medicine Podcast, Dr. David Bearss sits down with Dr. Evan Unger, physician-scientist, serial biotech entrepreneur, and pioneer in therapeutic oxygen delivery technologies.

Dr. Unger has spent decades working at the intersection of medicine, physics, and innovation. His work has focused on developing technologies that improve how oxygen is delivered to tissues in critical conditions such as cancer and heart attack. Tumor hypoxia, a state where parts of a tumor are deprived of adequate oxygen, has long been recognized as a major barrier to effective radiation therapy. Hypoxic tumors are more resistant to treatment, which can limit outcomes. Dr. Unger discusses why this problem has persisted since it was first described in the 1950s and why he believes his current work may represent one of the first meaningful approaches to reversing tumor hypoxia.

The conversation also explores the realities of being an inventor and biotech founder. Dr. Unger reflects on how having too many ideas can become a liability, and why focus, regulatory strategy, market opportunity, and disciplined value creation are essential for translating innovation into impact.

Finally, he shares why he remains driven by the possibility that new approaches to oxygen delivery could fundamentally transform treatment for heart attack, still the leading cause of death in the United States. This episode is about persistence, disciplined innovation, and pursuing breakthroughs that could change outcomes at scale.
