Jenna-Leigh Hoffmann is an author, doctoral researcher, integrative nutrition and functional health coach, entrepreneur, and endurance athlete whose work explores the intersection of human health, performance, and the rhythms that shape our lives. With a background spanning marketing, international business, health, and science communication, she brings a multidisciplinary lens to understanding how our biology interacts with time, light, movement, environment, and the way we structure modern life.

Jenna-Leigh is currently pursuing her doctorate at Aston University, where her research examines how organizational time structures influence circadian alignment, physiological regulation, and employee wellbeing. She is also the creator and host of In Rhythm, a podcast exploring the science and lived experience of human alignment through conversations with scientists, physicians, athletes, practitioners, entrepreneurs, and explorers.

A lifelong multi-sport endurance athlete, Jenna-Leigh’s experiences across triathlon, ultrarunning, modern pentathlon, freediving, yoga, and sailing have shaped her curiosity around physiology, resilience, and human potential. That same curiosity extends into Soleil Sailing, a sailing initiative she created to use ocean voyages as a platform for preventative health, fundraising, storytelling, and deeper connection with the natural world.

She is the author of Becoming Sunshine: Fine-Tune Your Health and Happiness, Harnessing Key Lessons from the Sun. Across her research, writing, podcast, coaching, speaking, and expeditions, Jenna-Leigh works to make complex science accessible and help people better understand the forces shaping their health, energy, and wellbeing.
