William Li is a physician and globally recognised thought leader in angiogenesis — the science of how blood vessels grow and its profound impact on human health.
As CEO and co-founder of the Angiogenesis Foundation, Li has spent over three decades translating breakthrough science into real-world health innovations. Trained in the lab of Dr. Judah Folkman, the pioneer of angiogenesis, he has helped bridge laboratory discoveries with clinical applications across oncology, cardiology, ophthalmology, wound healing, regenerative medicine, and more.
Beyond the lab, Li is an advocate for preventive health and longevity. Drawing on decades of research, he demonstrates how everyday lifestyle choices (particularly the foods we eat) can profoundly influence disease prevention, immunity, stem cell activity, and vascular health. His research shows that while genetics contribute only about 5% to our health outcomes, lifestyle factors like diet, sleep, and environmental exposures determine the majority of our longevity potential.
Li’s research has appeared in Science, The New England Journal of Medicine, The Lancet, Nature Reviews, and other leading journals. He has testified before Congress and lectured to audiences worldwide, translating complex science into actionable insights for clinicians, policymakers, and business leaders alike. His TED Talk on angiogenesis has reached over 11 million viewers, showcasing his talent for turning cutting-edge science into compelling, human-centered stories.
William Li’s bestselling books, Eat to Beat Disease and Eat to Beat Your Diet, explore how food can be harnessed to prevent disease, improve energy, and promote thriving over a lifetime. With memorable analogies like comparing human physiology to “Hershey’s Kisses” or describing the immune system as a “silent defender,” Li makes sophisticated biology relatable and actionable for diverse audiences.
As a speaker, Li offers unique perspectives that intersect medicine, biotechnology, nutrition, and lifestyle. He inspires audiences to rethink how science, food, and behaviour can be leveraged to extend health, prevent disease, and optimise human potential.
