Magdalena Żernicka-Goetz studies one of the strangest, most profound transitions in biology: the moment a cluster of cells begins to organize itself into something recognizably alive.
Her work asks questions that sit right at the edge of science and philosophy. How does an embryo know what to become? How do cells decide where to go, what role to take on, and when to act? How much of that early architecture is programmed, and how much emerges through interaction?
Magda is a developmental biologist at Caltech whose laboratory has helped pioneer stem cell derived models of early embryos, creating systems that allow scientists to watch processes that were once almost impossible to observe directly. Her group has built increasingly sophisticated models of mouse and human development, including structures that mimic aspects of the earliest stages of embryonic organization.
The work is technically extraordinary, but also deeply consequential. These models are helping scientists understand why some pregnancies fail, how congenital disorders begin, and what happens during the first days of development, when so much is being decided and almost none of it is visible.
I photographed Magda at the Athenaeum at Caltech.
Few of my subjects have taken greater care with a portrait session.
She has an extraordinary eye. She notices the way fabric falls, how a hand sits in a frame, where the light lands, the relationship between color and background. There is a deep appreciation for design and beauty in the way she moves through the world.
And after spending time with her, that felt entirely consistent with the science.
Her work is about form emerging from apparent simplicity. Cells arranging themselves. Structure appearing. Order becoming visible.
There is something almost architectural about it.
What I liked most, though, was that Magda brought the same seriousness to being photographed that she brings to the laboratory. She understood that a portrait is built through details, and that details matter.
That made the session feel less like a sitting and more like a collaboration.
