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.

Someone takes a melatonin gummy at 11pm, scrolls for another forty minutes because the show isn't over, and wonders the next morning why the gummy "didn't work." It's not a failure of willpower or a bad batch of gummies. It's a mismatch between what melatonin actually does and what the supplement aisle has trained people to expect…
You crash at 3pm and reach for something sweet before you've decided to. You lie awake Sunday night for no reason you can name. Most people file these under personality and move on. But a small, almond-sized structure at the base of the brain is running most of it — and it does something no other part of the brain can…
There's a tidy story the internet likes to tell: your brain peaks in your midtwenties, and after that, it's all decline. It makes for good headlines. It's also wrong. When Hartshorne and Germine ran what's still one of the…
Your body doesn't age all at once. It ages one cell at a time — and more specifically, through a population of cells that are too damaged to divide but not damaged enough to die. These are called senescent cells. And the…
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…
