About

Dr. Stephen Rose

I’m a scientist, fitness professional, and author passionate about the science of aging. With a PhD in bioengineering and decades of hands-on experience in human performance, I explore how biology, lifestyle, and technology intersect to shape the way we age—and how we might do it better.

My writing has appeared in peer-reviewed academic journals as well as popular science outlets like Lifespan.io, where I’ve authored more than 40 deep-dive articles on healthspan, neuroscience, and emerging longevity research. I aim to make complex science both accessible and actionable.

My passion for aging science began with the people I’ve loved and cared for—my grandparents, my clients, my family. I’ve worked in labs, taught fitness, and walked beside those growing older with grace and grit. Geronimo.life is my way of honoring that journey—asking better questions about how we age, and sharing what I learn along the way.
