Description
The AACR Anna D. Barker Basic Cancer Research Fellowship encourages and supports postdoctoral or clinical research fellows to establish a successful career path in cancer research.
This fellowship provides a two-year grant of $110,000 to support the salary and benefits of the fellow while working on a mentored basic cancer research project. Funds may also be designated for non-personnel expenses, such as research/laboratory supplies, equipment, publication charges for manuscripts that pertain directly to the funded project, and other research expenses.
Research Project Criteria
The research proposed for funding may be in any area of basic cancer research.

1. Strong preliminary data
AACR panels expect high-quality, convincing pilot data. Successful applicants demonstrate:
Mechanistic feasibility
Biological signal
Proof-of-principle in at least two systems (e.g., cell line + in vivo)
Biomarker rationale where relevant
Weak or minimal preliminary data is the most common rejection cause.
2. Clear translational potential
AACR heavily values clinical relevance:
Patient-driven hypotheses
Biomarker-driven trial concepts
Therapeutic target potential
Realistic proximity to clinical application
Funding tends to favor proposals that can impact patients within 3–7 years.
3. Cancer relevance that is explicit and justified
A common failure mode: cancer linkages that feel “tacked on.”
Winning applicants explicitly:
show pathway relevance to cancer biology,
outline patient populations,
reference tumor heterogeneity,
map existing clinical unmet need.
4. Track record of productivity
Successful applicants typically demonstrate:
1–3 first-author cancer manuscripts (recent)
Co-authorship in diverse oncology subfields
Conference abstracts (ASCO, AACR, ESMO)
Even early-career winners have measurable momentum.
5. Feasible scope within award duration
Panels flag:
overly ambitious aims,
multi-omics everything-everywhere plans.
Winning applications present:
clear milestones,
2–3 aims,
defined decision points.
6. Strong mentorship (for early-career awards)
Predictors:
active publication record of mentor
demonstrated prior mentoring success
multiple mentors (computational, clinical, basic)
Weak mentorship statements correlate with low scores.
7. Institutional environment
AACR reviewers value:
core facilities access,
tumor biobank availability,
genomics platforms,
animal facilities,
clinical trial access.
Letters confirming facility access improve panel confidence.
8. Innovation that’s grounded, not speculative
Winning proposals tend to:
address mechanistic novelty,
leverage cutting-edge platforms,
avoid “hand-wave” future benefits.
Innovation must be operationalizable.
Historically stronger funding rates for projects involving:
Tumor immunology & microenvironment
Resistance mechanisms to targeted therapies
Biomarker discovery + validation
Single-cell / spatial biology approaches
Computational oncology with validation
Drug repurposing with mechanistic rationale
Predictive design elements include:
Patient-derived samples / organoids
Clinically annotated cohorts
Mechanism → biomarker → targeted therapy progression
“Unclear how results would change clinical practice”
“Lacks specificity in experimental design”
“Unrealistic number of aims”
“Weak contingency plan”
“Cancer relevance insufficiently justified”
Panels reward:
attention to replicates,
power calculations,
batch effect mitigation,
blinded scoring methods.
Rigor & reproducibility paragraphs make or break applications.
Successful applications often show:
access to clinician collaborators,
biostatistics support,
immunology partnerships,
computational co-investigators.
“Solo silo science” is penalized.
AACR reviewers are sensitive to:
overpriced consumables,
excessive personnel allocations,
irrelevant equipment purchases.
Lean budgets with central facility usage score higher.
Recent cycles show:
emphasis on disparity-focused work,
access inequity,
demographic representation,
under-studied cancers.
Proposals that engage diverse populations score better.
Typical successful profiles display:
consistent productivity,
early independence signals (co-PI, first-/senior-author),
integrated cancer seminar participation,
AACR meeting involvement.
Many winners previously presented at AACR conferences.
Historically poor performance:
purely computational studies with no wet-lab validation
purely descriptive omics
overly incremental projects
indirect cancer hypotheses
Translational relevance
Preliminary data strength
Project feasibility
Mechanistic depth
Applicant trajectory
Innovation
Environment
Budget efficiency
In that rough order.
Projects that connect:
experimental biology
→ biomarkers
→ trial pathways
→ therapeutic decision-making
score extremely well.
A competitive AACR application generally has:
✅ clear clinical unmet need
✅ rigorous preliminary data
✅ mechanistic innovation
✅ translational biomarker strategy
✅ strong mentors/collaborators
✅ feasible, milestone-driven aims
✅ environment with cancer infrastructure
✅ attention to rigor & reproducibility
