The Simons Foundation’s Mathematics and Physical Sciences (MPS) division invites applications for the Simons Fellows in Mathematics program to make sabbatical research leaves more productive by extending them from a single term to a full academic year. Please note that in the event of budgetary or other considerations, The Simons Foundation, Inc. reserves the right to refer an application to The Simons Foundation International, Ltd. (SFI) for consideration and funding, in which case SFI’s grant policies would apply.
Sabbatical research leaves from classroom teaching and administrative obligations can provide strong intellectual stimulation and lead to increased creativity and productivity in theoretical research.
Awards will be based on the applicant’s scientific accomplishments in the five-year period preceding the application and on the potential scientific impact of the work to be done during the leave period.
A Simons Fellowship in Mathematics provides salary replacement (inclusive of both salary and fringe benefits) for up to 50 percent (up to a maximum of $125,000) of the Fellow’s current academic-year salary, whether normally paid over 9, 10 or 12 months, and up to an additional $10,000 for expenses related to the leave. The Fellow’s home institution will receive an additional 20 percent overhead on allowable direct cost expenditures, per the foundation’s indirect cost policy. The maximum total budget request should not exceed $162,000 USD.
The Simons Fellowship will fund up to 50 percent of the 2026–2027 academic year, where, for example, the full leave year period could be January 1, 2026, through December 31, 2026; September 1, 2026, through August 31, 2027; or January 1, 2027, through December 31, 2027. Fellowship funding must be contiguous to the university-supported portion of the leave.
Fellowship awards and sabbatical periods may begin no earlier than January 1, 2026, and no later than January 1, 2027. For sabbaticals beginning January 1, 2026, awards will be retroactively started and grant funds available no sooner than March 2026.
Salary replacement funds are to be used only to replace or partly replace salary during academic terms in which the recipient would otherwise be teaching or engaging in academic administration or other departmental or university committee work. The funding may not be used for summer salary (if salary is paid over nine months) or to increase the academic-year salary beyond the university rate but may be paid out over the course of the full leave. Please follow the university’s policy on costs associated with sabbaticals not supported by the university. If applicable, fringe benefits are allowed within the salary-replacement-funds category, but the total amount requested cannot exceed the maximum allowed ($125,000).
The additional funding is to be used to support expenses related to the leave in a manner consistent with the approved sabbatical plans. Allowable leave-related expenses include small equipment and supplies, travel (including the Fellow and the Fellow’s family members to and from the sabbatical location(s) and the Fellow’s travel to meetings and collaborators), housing (for the Fellow and the Fellow’s family), automobile rental, childcare and support for visitors (including meals). Salaries for students or research associates will not be supported, but funds may be used to help transport members of the Fellow’s research group to the sabbatical location (if different from the home institution) and provide housing. Leave-related expenses may be incurred at any time during the award period; they are not restricted to the terms in which salary is provided by the foundation.
Unspent funds at the end of the grant must be returned to the foundation. No-cost extension requests will typically not be considered.
The foundation expects to award up to 50 mathematics fellowships for 2026.
Simons funds discovery-driven research in mathematics, physical sciences, life sciences, and autism via SFARI. Grants are competitive and focused on fundamental, high-risk/high-reward ideas .
Programs like Simons Investigators require a proven record of exceptional scholarship and provide $100K/year for 5 years to enable long-term, high-risk studies .
The Simons Collaborations (including Neuroscience and Origins of Life) target high-impact, interdisciplinary questions and are funded over 10 years (~$5–12M/year) .
Successful teams are diverse, cross-disciplinary, include junior investigators, and commit to open science—sharing data/code across labs .
The foundation supports early-career faculty through Simons Early Career Investigator Awards and supports sabbaticals with Simons Fellows—both aimed at nurturing independent research paths .
SFARI specifically offers Bridge-to–Independence, Pilot, Explorer, and Research Awards to drive autism-related investigation forward .
Projects must map to the foundation’s core focus: core mathematics, theoretical physics, computation, basic life science, or SFARI’s autism mission .
Submit proposals for areas like ocean ecology, "origins of life," or global brain physics only if explicitly featured in current calls .
Large grants require institutional capacity to support collaborative teams and manage long-term activities
Coordination across institutions, project milestones, and administrative readiness are crucial for success in multi-institutional initiatives.

🔧 Recommendations
Target the right program: Investigator Awards for individual excellence; Collaborations for large-scale consortium science.
Demonstrate bold interdisciplinarity: Involve collaborators with diverse expertise and share resources openly.
Highlight your track record: Showcase publications, prior grants, and leadership roles.
Engage early-career co-investigators: Especially important for collaboration-focused proposals.
Ensure institutional commitment: Show administrative infrastructure and project management plans.
Craft innovative, foundational questions: Avoid incremental proposals—aim for frontier science.
Eligibility is restricted to sabbatical or equivalent leave-eligible faculty who wish to use the Simons Fellowship award for the purpose of extending at least a single-term sabbatical research leave to a full academic year without teaching or administrative responsibilities. The fellowship program will not support the extension of a full year of sabbatical research leave to an additional term. In order to receive the fellowship, you must be approved by your institution for a full year of sabbatical research leave, consisting of two consecutive semesters or three consecutive quarters with at least 50 percent of the year fully paid by the home university and no more than 50 percent fully or partly supported by the fellowship. Note: A research leave provided by a unit of a university, rather than the university-level sabbatical leave, would not normally be considered as sabbatical equivalent. Please contact mps@simonsfoundation.org with any questions concerning this.
If funds from the foundation are insufficient to cover the salary needs for the period supported by the fellowship, other resources can be used for this purpose. The foundation will consider circumstances where, for example, the university covers 80 percent of a full year of leave and the fellowship covers the remaining 20 percent.
Verification of sabbatical approval is not required at the time of application but must be provided to the foundation at least three months prior to the start of the applicant’s award. Please see the How to Apply tab for further information.
A Simons Fellow in Mathematics must have a teaching or administrative tenured position at the same U.S. or Canadian college or university within the mathematics department at the time of application, throughout the course of the sabbatical research leave and in the term following the leave. This must be the applicant’s primary position. Applied mathematics and statistics disciplines are eligible as long as the applicant resides within the mathematics, and not statistics, department. Those doing primarily mathematical education research are not eligible. In addition, a Fellow must have an active, current research program. Fellows cannot simultaneously hold a Simons Investigator award.
Previous fellowship awardees are allowed to apply for another fellowship as long as they follow their universities’ rules on sabbatical or equivalent leave eligibility.
Simons Foundation employees who receive a W-2 (Wage and Tax Statement) from the Simons Foundation, including employees of the Flatiron Institute, may not apply as a principal investigator (PI) to any Simons Foundation or Simons Foundation International requests for applications (RFAs) released by the Simons Foundation. PIs and any project personnel listed on the application who will receive funding for salary, travel, support for students, postdocs or research staff, lab equipment, computing time or other individual expenses may not be employees of the Simons Foundation, which includes the Flatiron Institute.
