After a highly competitive selection process, the John Quincy Adams Society is pleased to announce its Spring 2026 cohort of Marcellus Policy Fellows. This is the Society’s twelfth cohort of fellows. The Fellows will spend the next eleven weeks learning from top experts on foreign policy as they develop a think tank style policy analysis on a pressing issue facing U.S. strategy. They will also be trained to produce supporting materials to make their work more likely to have impact, culminating in production of an op-ed and a one-page policy memorandum. Past fellows have gone on to work at a number of prominent foreign policy institutions in government, academia, the media, and think tanks. You can read the bios of our Spring 2026 Fellows below.
