  • From Genomics to Healthspan: Dr. Wei-Wu He’s Vision for Preventing Disease
    Jan 7 2026

    In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dr. Wei-Wu, Executive Chairman at Human Longevity, Inc. Together, they explore how advances in genome sequencing, AI, and multi-layered diagnostics are changing the fight against age-related diseases. Wei-Wu shares why understanding your own genetic risks and combining them with other health data leads to better prevention and a longer healthspan.


    Wei-Wu explains the value of integrating genome sequencing, advanced imaging, and liquid biopsy to catch diseases like cancer early, before symptoms appear. He draws on real-world examples, including how combining different tests can spot cancers that single methods might miss. The conversation highlights how technology brings down costs, making once-rare insights widely available, and how each person stands to benefit from personalized risk profiles.


    The episode closes with practical advice: use today’s tools to become the CEO of your own health. Wei-Wu urges listeners to embrace data-driven, individualized care and stresses that no single tool or habit holds all the answers. Instead, true longevity comes from a holistic, ongoing approach, one that uses all available knowledge to prevent disease and extend both life and health.

  • The Gut–Brain Axis: A New Frontier in Longevity with Dr. Emeran Mayer
    Dec 3 2025

    In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dr. Emeran Mayer, Executive Director at the UCLA Center for Neurobiology of Stress and Resilience and founder of Mayer Interconnected. They explore the science behind the gut-brain connection and its role in shaping health and longevity.


    Emeran explains how signals flow between the brain, gut, and microbiome, influencing everything from digestion to emotions. He breaks down how modern diets, especially ultra-processed foods, disrupt the natural balance between humans and gut microbes—a relationship refined over thousands of years. The conversation highlights why early life exposure to antibiotics can have lasting effects on microbiome resilience, and how lifestyle choices like diet and exercise remain powerful tools for supporting gut-brain health at any age.


    The discussion closes with a look toward the future of gut-brain science, including engineered probiotics and the promise of more targeted therapies. Emeran shares practical habits for better gut-brain health and cautions against quick-fix “biohacking,” encouraging a return to whole foods, movement, and mindful living.
