Translating the science of human health into language that you can use to make your life better. I write about the body, the brain, and what it means to live well — rigorously, and without the noise.
About
I'm a scientist with a deep interest in the intersection of biology, behaviour, and human flourishing. After years working in research, I felt the gap between what the science actually says and how people talk about wellness — and decided to do something about it.
My writing explores neuroscience, longevity, sleep, stress physiology, and the everyday choices that compound over a lifetime. I care about evidence, nuance, and making ideas useful — not just interesting.

Your driver's license says one age. Your epigenome says another. And for predicting how well you're actually aging, the epigenome turns out to be the better witness. In 2013, a researcher named Steve Horvath published a paper…
The brain fog that shows up around perimenopause isn't forgetfulness. It isn't a character flaw. It's a hormone pulling a transcription factor off your DNA. Most people think of estrogen and testosterone as vaguely related to…
One number from the stroke research never gets enough attention: 88%. Roughly 88% of stroke risk is attributable to modifiable lifestyle factors. Eight in ten strokes don't have to happen. Nearly 800,000 Americans have a stroke…
