A biosketch is a standardized document used in federal grant applications that summarizes a researcher’s qualifications, experience, and scientific contributions. Unlike a CV or resume, which lists everything you’ve done, a biosketch is a focused, curated snapshot designed to show reviewers that you’re the right person to carry out a specific project. Both the National Institutes of Health (NIH) and the National Science Foundation (NSF) require biosketches from every senior or key person named on a proposal.
How a Biosketch Differs From a CV
A curriculum vitae is a comprehensive record of your entire career. A biosketch is not. It asks you to select only the qualifications and contributions most relevant to the proposed work, then present them in a prescribed format. Grant reviewers use it to assess how well qualified you are to conduct the activities described in your application, so every element should connect back to the project at hand.
This means you’ll likely need different versions of your biosketch for different proposals. A contribution that’s central to one application may be irrelevant to another. Treating the biosketch as a static document you submit unchanged is one of the most common mistakes applicants make.
Required Sections for NIH Biosketches
The NIH biosketch collects three required sections, established under federal peer review regulations: a Personal Statement, Contributions to Science, and Honors.
The Personal Statement is a brief narrative where you explain why you’re well suited for this particular project. This is your chance to connect your background, training, and prior work directly to the proposed research. You can cite relevant publications or research products here to support your case.
The Contributions to Science section is where you describe your most significant scientific accomplishments. Rather than listing every paper you’ve published, you group your work into a handful of distinct contributions and explain the impact of each one. For each contribution, you include a short narrative and cite the most relevant publications associated with it. This section rewards clarity and selectivity over volume.
The Honors section is straightforward: a list of your relevant awards, honors, and recognition.
NSF Biosketch Requirements
The NSF biosketch follows a similar philosophy but has its own rules. One notable change took effect in May 2024: biographical sketches for NSF proposals no longer include information on synergistic activities. Those activities, which demonstrate the broader impact of your professional and scholarly work, must now be submitted as a separate one-page document.
The Synergistic Activities document allows up to five distinct examples that show how your work contributes to the creation, integration, and transfer of knowledge. Think of activities like mentoring, curriculum development, community engagement, or open-source tool building. You prepare this as a separate PDF and submit it alongside your biographical sketch.
Formatting With SciENcv
Both NIH and NSF now use a shared system called SciENcv (Science Experts Network Curriculum Vitae) to generate biosketches. For NSF proposals, using SciENcv is mandatory. The system produces a compliant PDF that you then upload through Research.gov or Grants.gov.
SciENcv can pull in data from other sources like your ORCID profile or PubMed publication records, which saves time. But you still need to review and tailor the output for each application. The system also includes certification language: senior and key personnel must certify that their information is current, accurate, and complete, including details about domestic and foreign appointments and positions.
For NIH applications with due dates on or after January 25, 2026, the agency is implementing a new Common Form for the biographical sketch. Under this updated format, there is no page limit for the combined Biographical Sketch Common Form and NIH Biographical Sketch Supplement PDF. This is a shift from the previous five-page cap, though the expectation remains that biosketches should be concise and relevant.
Writing an Effective Biosketch
The strongest biosketches read like an argument, not a list. Your personal statement should make a clear case for why your specific combination of skills and experience positions you to succeed with this project. Vague language about being “passionate” or “experienced” does little. Concrete details about past results, completed projects, and relevant expertise give reviewers something to work with.
In the Contributions to Science section, lead each entry with the narrative explanation before citing papers. Reviewers want to understand the significance of the work, not just see a bibliography. Explain what problem you addressed, what you found, and why it mattered. The publications are supporting evidence for claims you’ve already made in plain language.
Tailor every section to the specific proposal. If you’re applying for a clinical trial grant, foreground your clinical research experience. If you’re proposing computational work, highlight your methods development. Reviewers read dozens of applications, and a biosketch that clearly maps your background onto the proposed aims stands out from one that reads like a generic career summary.
Who Needs to Submit One
Every individual identified as senior or key personnel on a federal grant proposal needs their own biosketch. This typically includes the principal investigator, co-investigators, and sometimes consultants or collaborators who play a substantial role. If you’re listed on the project team and your expertise is part of the reason the project should be funded, you’ll need a biosketch.
For multi-investigator proposals, each person’s biosketch should address their specific role. A co-investigator responsible for the statistical analysis component, for example, should emphasize their quantitative methods experience rather than submitting the same biosketch they used for a different proposal where they led the data collection.
