Nick Tiller

Dr Nick Tiller is a research associate at the Lundquist Institute, Harbor-UCLA Medical Center, a science writer, and educator. He's the author of two books: "The Skeptic's Guide to Sports Science," which was named one of Book Authority's "Best Sports Science Books of All Time," and "The Health and Wellness Lie," described as "the systematic dismantling of a trillion-dollar con."

With a master's in kinesiology, Tiller worked as a performance physiologist on the UK’s Olympic program before earning his doctorate in Applied Physiology from Brunel University London. He has since held academic posts in the UK and Los Angeles, where his research at the prestigious Lundquist Institute focuses on exercise physiology, respiratory medicine, and the science of extreme exercise—a field he knows firsthand as an accomplished ultramarathon runner. His recent work examines health misinformation and questionable research practices.

A prominent voice in science communication, Tiller writes for Skeptical Inquirer and Ultra-Running Magazine and serves as associate editor for the International Journal of Sport Nutrition and Exercise Metabolism. He's authored more than 150 general-audience articles and is a frequent guest on television, radio, and podcasts. In 2023, he was named a Fellow of the Committee for Skeptical Inquiry for his commitment to promoting science literacy and critical thinking.
