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
