Who we chose as our experts.

Tenured Associate Professor of Neurobiology and Ophthalmology at Stanford School of Medicine, where he runs an active research lab studying the visual system, stress, and brain plasticity. The podcast translates his own research and that of guest scientists into actionable protocols around sleep, light exposure, focus, and physical performance — one of the most listened-to science podcasts in the world.

Holds an MSc in nutritional sciences from the University of Limerick and has spent more than a decade interviewing leading academic researchers in nutrition. Sigma Nutrition Radio is widely cited by other evidence-based practitioners as the field's benchmark for depth — Lennon reads the full papers his guests have published and presses them on methodology like a peer reviewer.

Founder and director of the Scripps Research Translational Institute and one of the most-cited researchers in modern medicine, with more than 1,300 peer-reviewed papers. On Ground Truths he interviews the scientists shaping the future of medicine — from cardiovascular disease and Alzheimer's prevention to AI-assisted diagnostics — with episodes anchored to specific papers in NEJM, Lancet, and Nature.

Eric Trexler holds a PhD in human movement science from UNC Chapel Hill and has published more than 30 peer-reviewed papers in exercise and sport nutrition. Greg Nuckols holds an MA in exercise science and is one of the most widely-read evidence-based writers in strength training. Their podcast is a journal-club format — they read full papers on air and dissect the methodology with the rigor of peer reviewers.

Emeritus Professor of Exercise Metabolism at Victoria University in Australia, with more than 30 years of research on skeletal-muscle glucose uptake and 120+ peer-reviewed publications. Inside Exercise is long-form interviews with the actual researchers shaping the field — John Hawley, Michael Joyner, Edward Coyle, Stuart Phillips — pressed on methodology by a peer who's read their papers.

Professor of Neuroscience and Psychology at UC Berkeley, where he directs the Center for Human Sleep Science. One of the world's most prolific sleep researchers and author of the bestseller Why We Sleep. His podcast is focused, single-topic explainers — each episode dedicated to one slice of sleep science, anchored to the specific studies he's drawing from.

PhD in biomedical sciences from the University of Tennessee, with postdoctoral work in the Bruce Ames lab at the Children's Hospital Oakland Research Institute. Her show is the most reference-dense in the genre — every claim linked to the primary literature in her notes, with topical deep dives on omega-3s, micronutrients, heat stress, and the biology of aging.

Professor of Genetic Epidemiology at King's College London and the principal investigator of TwinsUK — the world's largest adult twin registry — and the PREDICT nutrition trials. Author of multiple bestsellers on nutrition science. Co-host Jonathan Wolf brings a researcher's discipline to the format, and the guest list (Stuart Phillips, Satchin Panda, Christopher Gardner) reads like a Who's Who of academic nutrition.

Tommy Wood holds both an MD and a PhD in physiology and is an Associate Professor of Pediatrics and Neuroscience at the University of Washington, where he runs an active research lab. Joined by neurologist Josh Turknett, MD, the show works through the science of brain health, cognitive aging, and dementia prevention with clinician-researcher rigor — grounded in the actual literature.

Hematologist-oncologist and Professor of Epidemiology and Biostatistics at UCSF. Author of two books on medical evidence, and one of the field's most rigorous critics of how new drugs get approved. Plenary Session walks through the actual trial data behind oncology treatments, screening guidelines, and FDA decisions — a level of methodological scrutiny that is rare in medical media.
