Shreya Vangara started working on fusion reactors at Commonwealth Fusion Systems, where she was soldering magnetic coils designed to hold a piece of the sun on Earth. Then she realized the reactor was stalled not by physics, but by a cargo ship full of metal sitting in a Chinese port, held up by a trade dispute with Japan. “I could tell you everything that was to know about the physics and the chemistry and the material science of fusion,” she says, “but I couldn't tell you a single thing about treaties and diplomacy and international law.” That moment sent her to Beijing to study global affairs, and eventually to Stanford, where she is now a third-year PhD in mechanical engineering working on AI tools for battery design. Her career has been a series of pivots—from teaching robotics to girls in her Maryland library, to digging wells in the Navajo Nation, to building desalination devices out of trash in Madagascar—all held together by a single through line: bringing cutting-edge technology to communities that have been left out of the conversation.
