The DOE NNSA LRGF is open to U.S. citizens engaged in full-time, uninterrupted study toward a doctoral degree at an accredited U.S. university. Specifically, applicants should be first-, second- or third-year Ph.D. students with at least 18 months remaining in their academic program as of the start of the fellowship period (that being September 1, 2025 for 2025-26 cohort applicants). Candidates must also be pursuing research in fields of study supported by the DOE NNSA LRGF.
Fellows must complete a minimum of two 12-week laboratory residencies at one of five approved NNSA sites. Extended residencies of more than six months are encouraged, with combined experiences not to exceed 24 months. During the summer, fellows should conduct full-time research related to completing their degree, enroll in classes, or make progress toward fulfilling the laboratory residency requirement.
This equal opportunity program is open to all qualified persons without regard to race, color, national origin, sex, disability, or any other characteristics protected by law.
TA Policy: Freedom to Focus on Research
The DOE NNSA LRGF's support allows students to focus on their academics and research without excessive teaching or other departmental support activities. Each fellow's department must waive any teaching requirements beyond one term in order for the student to be accepted into the program. Please review our teaching assistant policy in full.

Annual Renewal and Availability of Funds
The fellowship must be renewed for each of up to four years. Online renewal applications must demonstrate acceptable academic performance, progress toward completing the approved program of study and laboratory residency experiences, and research consistent with program goals. Renewal is contingent on the availability of funds to meet the program's costs.
The DOE intends to provide adequate support to meet graduate school costs. Therefore, the Krell Institute must approve in advance any teaching or other academic department responsibilities. Fellows may accept scholarships, prizes and other payments (including veteran’s benefits) that do not require a service.
