The ballerina is an avatar of certain qualities—among them the ambition, skill, and courage to take bold leaps. Offstage, ballet lover Rachel Theios has infused those same characteristics into her budding research career in astronomy. Pursuing her first publication as a Caltech graduate student, she has shown the vision and bravery to question some of the fundamentals of her field.

Like many who come to Caltech to learn and explore, undergraduate Damien Bérubé dreams of changing the world with science and engineering. But his personal vision—the force that drives him in the classroom, the lab, and beyond—is an uncommon one.

Azita Emami’s work in high-speed data communications led to a breakthrough that could spare millions of people the need to prick themselves with needles.

Caltech graduate student Manuel Razo Mejia wants to predict how evolution occurs in organisms ranging from microbes to humans. Until recently, evolution has been considered a random process, but Razo Mejia believes we might detect certain patterns by applying the principles of physics and mathematics. To unravel the mystery of how biological systems change over time, he observes gene regulation in single-celled bacteria, whose brief life cycles enable him to witness change at an accelerated rate.

Erik Petigura marvels at how far his field of astronomy has come since his childhood in the early 1980s, when he first became hooked on science after watching Carl Sagan’s Cosmos series.
