A Handheld Device to Defeat Cancer | Mary Lou Jepsen

What if the bulky, expensive machines that fill hospital radiology departments could be replaced by a wearable? In this episode, we speak with Mary Lou Jepsen — founder of Openwater and pioneering inventor — about how breakthroughs in light-based imaging could democratize access to brain and body scans. From her work at Google X and Facebook’s moonshot labs to her current mission at Openwater, Jepsen has spent decades at the frontier of tech and health. Now, she’s building a future where scanning the body for disease is as simple as putting on a hat — no radiation, no giant machines, no $1M price tag.

We explore: Why light could be the key to affordable, real-time medical diagnostics How her device works — and what it might replace What it takes to challenge the medical-industrial complex Her vision for global healthcare access and early detection ‍ On the Existential Hope Podcast hosts Allison Duettmann and Beatrice Erkers from the Foresight Institute invite scientists, founders, and philosophers for in-depth conversations on positive, high-tech futures.
