An individual is eligible to submit a proposal if all the following criteria are met: Must be a U.S. citizen, U.S. national, or U.S. permanent resident, i.e. , have a "green card," at the time of submission. Must present a research plan that falls within the purview of BIO and that focuses on the research area described in this solicitation. Must earn the doctoral degree in an appropriate field prior to beginning the fellowship. Must select sponsoring scientists, departments, and institutions that offer a significant opportunity to broaden the proposer's research focus and training. Must not have submitted the same research to another NSF postdoctoral fellowship program. Must not have worked in any position that requires a doctoral degree for a combined total of more than 15 full-time months prior to the deadline. Must not have submitted proposals to the PRFB program more than once in previous years, i.e., you are limited to a maximum of two submissions, regardless of the outcome.

The UKRI Policy Fellowships 2025, funded by the Economic and Social Research Council, offer 18-month placements for academics to co-design research with UK government and What Works Network host organizations. Awards range from £180,000 to £280,000 and support three fellowship tracks: core policy fellows, Natural Hazards and Resilience policy fellows, and What Works Innovation fellows. Applicants must hold a PhD or equivalent research experience, be based at a UKRI-eligible UK organization, and possess relevant subject matter or methodological expertise. Government-hosted positions target early to mid-career academics, while What Works fellowships welcome all career stages. Fellows work directly with policymakers to bridge academic research and policy development on pressing national and global challenges. The application deadline is July 15, 2025.
The Smart Data Research UK Fellowships provide up to £200,000 per project for researchers using smart data to address real-world challenges across the United Kingdom. Funded by UKRI through Smart Data Research UK, this program supports up to ten projects lasting 18 months, with start dates by February 2026. Applicants must be based at eligible UK organizations and demonstrate strong data skills with a compelling research question aligned to one of four SDR UK themes: productivity and prosperity, health and wellbeing, sustainability, or communities and places. Researchers at all career stages may apply, with early career researchers particularly encouraged. Projects may use smart datasets from SDR UK's six national data services or combine smart data with administrative and survey data sources.
NSF's CAREER award pays a minimum of $400,000 over five years and is the agency's most prestigious grant for pre-tenure faculty. But the July 22 deadline hides a harder truth: CAREER is not a research grant with an education paragraph bolted on. Here is what the program actually rewards, who is eligible, how many attempts you get, and how to position a proposal that survives a brutal success rate.

The July 21 Scholarship Track deadline is a workforce-policy tell disguised as a grant. Here is what changed, who qualifies, and how universities should position.
Read articleNSF's Trailblazer Engineering Impact Award (NSF 26-502) gives a single principal investigator up to $3 million over three years to pursue a high-risk, field-defining project. The July 24 full-proposal deadline is invitation-only — the real contest happened months earlier. Here is how the three-stage structure works, who is eligible, why the no-co-PI rule is the point, and how to position for the next cycle.
