Starting with the 2028 competition, the Freeman Hrabowski Scholars and Hanna H. Gray Fellows Programs will select scientists through a single, combined competition. (Applicant review is specific to career stage.)
What the Program Offers
These are evidence-informed predictors based on HHMI's research philosophy, published program criteria and current fellowship competitions. Their relative importance varies by program; they are not a universal official scoring rubric.
★★★★★
Exceptional scientific potential and discovery orientation — Critical
Show potential to make important discoveries that advance fundamental understanding of biology or biomedical science. Strong applications ask significant questions and pursue insights that could change how a field understands a biological process, rather than merely extending established work.
HHMI
+1
★★★★★
Originality, creativity and scientific ambition — Critical
Present a compelling, original research direction and explain why conventional approaches are insufficient. HHMI values researchers who can pursue bold questions, take scientifically justified risks and develop new ways to investigate biological problems.
★★★★★
Applicant's achievements and future trajectory — Critical
Demonstrate scientific independence appropriate to career stage, intellectual ownership, strong research contributions and the capacity to pursue ambitious future work. For trainee programs, evidence of potential matters alongside current accomplishments.
★★★★★
Scientific rigor and a credible research approach — Critical
Define the central question, explain the conceptual rationale and show that the methods can generate interpretable evidence. Use appropriate controls, analytical approaches and alternative strategies without making the proposal so constrained that it loses its exploratory potential.
★★★★★
Mentorship quality and a healthy training environment — Critical for trainee programs
For the Gilliam Fellows Program, both the PhD student and faculty advisor are evaluated as a mentor–mentee pair. Show a meaningful mentoring plan, effective communication, conflict-resolution practices and a commitment to an inclusive research culture.
HHMI GIlliam Fellows Program
+1
★★★★☆
Commitment to inclusive scientific leadership — Very high
Demonstrate concrete actions that help create an environment where scientists with different backgrounds and experiences can contribute and thrive. For Gilliam, explain the student's leadership and the advisor's efforts to foster a healthy, supportive laboratory culture.

★★★★☆
Fit with the specific HHMI program and career stage — Very high
Match the application to Gilliam, Hanna H. Gray, Freeman Hrabowski Scholars, or the Investigator competition as appropriate. Each program has different requirements, institutional restrictions, and expectations for career development or research leadership.
HHMI Science Programs
+2
★★★★☆
Long-term potential and independence — Very high
Explain how the proposed work can lead to new scientific directions, greater independence, a distinctive research identity and sustained contributions to the field. Faculty applicants should articulate a coherent research vision rather than only a list of projects.
★★★☆☆
Collaboration, communication and scientific community contribution — High
Show how the applicant will benefit from and contribute to HHMI's scientific community. For mentor–trainee awards, clearly communicate scientific goals, professional development plans and shared responsibilities.
★★★★☆
Eligibility, institutional fit and application completeness — Essential gate
Confirm that the institution is eligible, the applicant meets the relevant career-stage and research-area requirements, and all required statements, letters and supporting documents are submitted. A scientifically excellent application cannot compensate for ineligibility.
