Credits: Image: Gretchen Ertl Next image Danielle Grey-Stewart, a senior majoring in materials science and engineering, is a fierce believer that public service and engineering go hand in hand. She aspires to be a leader in equitable science policy and plans on using her time at Oxford University, where she will be studying next year as a Rhodes Scholar, to study nature, society, and environmental governance. Despite her interest in public service, Grey-Stewart didn’t always see policy as a future career route. A passion for chemistry and understanding the physical world had led her to believe her goal was to become a cosmetic chemist. But a sophomore-year trip to visit the Navajo Nation marked a major turning point.
