No specified ceiling or floor; awards vary by project scope and duration, typically 3 years.

Supports fundamental and applied research in probability theory, including interdisciplinary applications.

Conference/workshop proposals should be submitted 8 months before the planned event.

--- ## Description This program provides funding for research on the theory and applications of probability. Supported subfields include discrete probability, stochastic processes, limit theory, interacting particle systems, stochastic differential and partial differential equations, and Markov processes. The program particularly encourages proposals that involve applications of probability to other areas of science and engineering. Funding is also available for conferences, workshops, and similar activities relevant to probability research. --- ## Due Dates - **Research proposals:** October 23–November 7, 2025 (annual window) - **Conference and workshop proposals:** Submit at least 8 months before the requested start date - **Other proposals:** September 16, 2025 (third Tuesday in September, annual) --- ## Funding Amount - **Award Size:** No stated minimum or maximum; varies based on project scope and needs. - **Typical Duration:** Awards are generally made for up to 3 years. - **Cost Sharing:** No cost sharing or matching required. --- ## Eligibility - **Eligible Applicants:** Unrestricted—open to all types of entities, including universities, colleges, non-profits, for-profits, and other organizations. - **Principal Investigators:** Individuals with expertise in probability or related fields. --- ## Application Process - **Submission:** Proposals must be submitted via [NSF FastLane](https://www.fastlane.nsf.gov/), [Research.gov](https://www.research.gov/), or [Grants.gov](https://www.grants.gov/search-results-detail/353353). - **Guidelines:** All proposals must adhere to the [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1). - **Conference/Workshop Proposals:** Review the [Conferences and Workshops in the Mathematical Sciences guidelines](http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=11701&org=DMS&from=home) and submit at least 8 months before the event. --- ## Additional Information - Proposals should clearly articulate the significance of the research and its potential impact on probability theory and related fields. - Interdisciplinary and collaborative projects are encouraged. - Recent updates to NSF research security policies require annual certifications and training; see [NSF Important Notice 149](https://www.nsf.gov/notices/important/important-notice-no-149-updates-nsf-research-security/in149) for details. --- ## External Links - [NSF Program Description PD-18-1263](http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=5555) - [Official Grants.gov Listing](https://www.grants.gov/search-results-detail/353353) - [NSF Probability Program Page](https://www.nsf.gov/funding/opportunities/probability) - [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1) - [Browse Recent Awards](https://www.nsf.gov/awardsearch/advancedSearchResult?ProgEleCode=126300&BooleanElement=Any&BooleanRef=Any&ActiveAwards=true#results) --- ## Contact Information | Name | Email | Phone | Organization | |-----------------------------|-------------------------------------|---------------|----------------| | Tomek Bartoszynski, Program Director | [tbartosz@nsf.gov](mailto:tbartosz@nsf.gov) | (703) 292-4885 | MPS/DMS | | NSF Grants.gov Support | [grantsgovsupport@nsf.gov](mailto:grantsgovsupport@nsf.gov) | | NSF |
