Welcome. This newsletter is a pause.
A place for slower thinking about fast-moving science, and for essays that sit at the intersection of early life biology, stem cells, and how experience, sometimes lasting only days, can leave marks that shape health decades later.
I started writing these essays after years of publishing scientific papers and giving talks where complexity was compressed and uncertainty smoothed over. That pressure only grows in our world of short attention spans and clickable headlines that reward certainty. Even when science, by nature, is an entry point to ask more questions and anything but certain. Writing here lets me slow things down: to expand, reflect, and invite readers into the process of science, not just its conclusions.
Once a month, I’ll send a short note about what I’ve written recently on my website, why it matters, and maybe what surprised me along the way.
Your guide to this month’s essays
Quiet Writing in a Loud World - On Science, Democracy, and the Courage to Speak Up
This first essay sets the tone for this whole project.
Here, I reflect on why writing openly and honestly about science matters in an era of noise, misinformation, and false certainty. It is a call for scientists, and all of us really, to slow down, embrace uncertainty, and participate more fully in the civic and social context of our work. I sat with the idea for this piece for a long time. Over a year, in fact. But once I started writing, it flowed quickly.
“Contrary to outside perspectives science is not purely objective, and it is certainly not apolitical. With the recent weaponization of information and the strings attached to scientific research funding, I don’t think we can pretend otherwise anymore. When we pretend that science is neutral, as many of us have for far too long, we open the door to the misuse of science for authoritarian purposes.”

Less Noise, More Signal - On risk, uncertainty, and the humanity of science
We can’t talk about the uncertainty in science without discussing probability.
This essay explores why science speaks in probabilities rather than guarantees. How flashy headlines and demands for certainty distort what evidence can actually tell us. Using examples from health research and early‑life biology, I present a case for embracing uncertainty as a fundamental and human feature of science.
“Eat this one food to live longer! 10 easy steps to a healthier you! If it sounds too good to be true, it almost certainly is. Health—and life—is all about risk, not guarantees. Science is not certainty, science is human. Pretending otherwise undermines our trust in science and, ultimately, our trust in the truth.”

What five days of fat taught us about muscle health
This is the first in my From the Paper series, where I revisit my published research, from the beginning.
Revisiting my first clinical research study, we asked how human muscle adapts to a short, high‑fat diet. And why those responses differ so markedly between people.
“Our goal was to capture very early molecular signals, within hours or days, of how muscle responds to increased dietary fat. In short, just five days of a high‑fat diet revealed markedly different molecular responses in the skeletal muscle. These patterns reflect metabolic flexibility in the normal‑weight group: muscle sensing more dietary fat and shifting toward using more of it. In obesity, this response was severely blunted.”

Small cells, big futures - How our earliest cells shape and maintain our health
This essay steps back from health headlines to focus on progenitor cells
My research focuses on progenitor cells, the earliest cells that shape how our bodies form, adapt, and maintain health across the lifespan. Here, I introduce these cells as a way of understanding how early biological decisions influence risk, resilience, and possibility long before disease appears.
“Beneath all the noise about health optimization, there is a quieter story. One that begins at the smallest possible scale, long before we even enter the world. Once, you were a cell. Just a single cell for a brief moment in time. A single fertilized egg, a zygote, holding the instructions for all that comes next: your eyes, your bones, your knees that will heal from your first and last scrapes.”

What our muscle cells remember - A look at how metabolic inflexibility persists, even outside the body
Another early research study for my From the Paper series
By revisiting early work on skeletal muscle satellite cells, I explore how metabolic inflexibility may be preserved at the cellular level, helping explain why people respond so differently to the same diets and environments.
“We often talk about health as if it’s something we can fully control. If you eat better, sleep more, exercise harder, take the right supplement… better health will follow. These messages not only ignore the very real barriers many people face because of time, money, and access, they also ignore our biology. By growing donor muscle cells in the lab, we can strip away the behaviors, hormones, and environmental influences, allowing us to ask whether muscle cells themselves differ.”

Across these essays runs a common thread: science is not just a set of conclusions, but a process shaped by time, context, and uncertainty. This newsletter is an invitation to pause with that process. To look closely at early biology, long‑term health, and the signals that emerge when we resist the urge to simplify too quickly.
I’m grateful for your attention, and glad you’re here.
