Argonne Air Force Fellows

Promoting communication between the Air Force and Argonne, encouraging collaborations that benefit the departments of Energy and Defense.

Each year, two fellows are placed at Argonne for the prestigious one-year national program to conduct research on an area of their choice. Fellows are selected through a rigorous review based on merit, rank in their respective career fields, and education and experience relevant to Argonne’s mission.

The Air Force Fellows program maintains and strengthens a longstanding relationship between the laboratory and Air Force, and reinforces the key role played by Argonne’s national security programs.
