Statistician. Researcher. Artist.
By day, I work on clinical trials for artificial heart valves — devices for people in severe heart failure whose bodies are giving out. The patients in my studies are facing the worst outcome there is, and the statistics I write help determine whether a new valve will give them more time. It's precise work.
My training is in causal inference and targeted learning — I did my Ph.D. at UC Berkeley, building statistical methods for understanding cause and effect in complex systems. Before that, I studied philosophy and cognitive neuroscience. I've always been drawn to how things connect — how the structure of a system reveals something about what it does, what it means.
The honest truth is I've never been naturally gifted at math. Compared to my colleagues at Berkeley, I was the one who had to draw things out — literally sketch the geometry of a problem before I could understand it. That turned out to be the whole point.
Over ten years ago, I had a simple idea: a circle sitting on top of a parabolic curve. Just that. It looked like solitude to me — a single form resting in a basin, alone but stable. I started sketching more: what does grief look like as a function? What shape does connection take? I realized quickly that coding these — the way I'd been trained to build statistical models — was the right medium. Python, not pencil.
So I started building. I collected equations the way other people collect records — exponential decay for grief, coupled oscillators for connection, L-system branching for growth. Each one a mathematical system that genuinely behaves the way an emotion does.
This became my craft. Something that made me feel like a kid again — at play, using everything I'd learned, but pointed in a completely different direction.
These pieces are all a product of that journey. I'm happy to share them in a world that feels increasingly confusing and flooded with AI-generated noise. This is intentional work that tries to cut through — to get back to what is fundamentally human: the mathematical language of the universe and the experience of being alive in it.
The Work
How Each Series Is Made
It always starts with the emotion. I sit with it, study it — what does this feeling actually do over time? Then I go looking for the math that behaves the same way. Once I find it, I write Python code and render thousands of parameter variations: different palettes, densities, compositions. Most of them get rejected. The ones that survive pass one test — they make me feel the thing they claim to represent.
The Code
# GRIEF — Settling # f(t) = e^(-λt) · cos(ωt) t = np.linspace(0, 1, 2000) lam = 3.5 # decay rate — how fast grief fades omega = 22 # frequency — how often it returns ys = baseline + PH*0.44 * np.exp(-lam*t) * np.cos(omega*np.pi*t)
The decay rate (λ) controls how fast the waves shrink. The frequency (ω) controls how often grief returns. I chose the parameters because they felt true.
No AI Generated Images
Every line in every piece traces back to an equation I wrote by hand in Python. No image generators, no style transfer, no prompts. The equation at the bottom of each piece isn't a label — it's the reason the image looks the way it does.

The final question I ask of every piece: if this were hanging in a gallery with no label, would someone stop and feel something?
