Simons Collaborations in Mathematics and the Physical Sciences

Deadline for Letter of Intent (LOI) Submission: October 29, 2026, 12 p.m. (noon) Eastern time. Late applications will not be accepted.

Create the LOI:

LOIs must be submitted via the Simons Award Manager (SAM), https://sam.simonsfoundation.org/. Click on the Funding Opportunities icon. Applications should be started and submitted under the applicant’s own account in the Simons Award Manager (SAM). For the Simons Collaborations in Mathematics and Physical Sciences application, click on Create Application and then on Begin Application. After creating an application, navigate to the Awards and Applications table on your homepage to access the in-progress application.

Important Notes:

• The collaboration director (referred to in SAM as the Spokesperson PI) must submit the LOI —be sure that the director’s profile in SAM is associated with their current institution.
• If the LOI is approved, a full proposal application will be created for each PI designated as a Principal Investigator (Collaboration) role at the LOI stage and must be submitted to the Spokesperson PI’s application for submission to the foundation.
• The director is the designated contact for the collaboration and will be responsible for coordinating the submission of PI applications and the project narrative, as outlined below.
• If the collaboration proposal is awarded, each PI in the Principal Investigator (Collaboration) role and the director will receive their own award, and their institution will be paid separately.
• Multiple PIs at the same institution can either receive individual awards or reside on one award via one proposal budget. This is entirely at the discretion of the director.
• The director now has the ability to view the budget details for each PI once their application is in a Submitted to Spokesperson PI status by clicking on the View button in the Budget tab of each PI application record. Note that the salary information is masked for confidentiality.

LOI and proposal attachments should be single spaced and in a common typeface and font size no smaller than 10 points. Margins must be at least half an inch in all directions.

5. Budget Tab: Click the Edit/Modify button to add a detailed, four-year budget in USD and corresponding justification. Refer to the allowable expenses outlined in the RFA.
   1. Each PI and director budget must be entered only in their respective applications.
   2. Note: Please be cognizant of the notification and award start dates when preparing the budget, particularly in year one with regards to the timeline for the hiring of postdoctoral fellows.
   3. Enter each PI on each proposal in the Personnel Costs section of that proposal budget even if not requesting salary in order to reflect the PI’s percent effort.
   4. For PIs and co-Is requesting summer salary with a 9- or 10-month appointment, please only select Academic for the Appt Type (which refers to the individual’s institutional appointment) and the base salary corresponding to this appointment type. The percent effort should then be adjusted accordingly.
   5. For PIs and co-Is requesting summer salary at non-U.S. institutions and/or those receiving 12 months of salary, the program allows them to request up to 1/12 of their calendar year salary as a contribution to research time on the project, only if an exception exists where their institution permits extra compensation for specific, separate activities outside of regular duties and provided that the summer salary request is not in violation of their institution’s policies of more than 100 percent effort per year. Please only select Annual for the Appt Type (which refers to the individual’s institutional appointment) and the base salary corresponding to this appointment type. The percent effort should then be adjusted accordingly.
   6. Important: In order for known project personnel to display in the Personnel column drop-down list, you must add them as Project Personnel in the Contacts & Personnel tab of the application as well as add an application role to each personnel using the Add More Details button. You will need to close and reopen the budget for the changes to populate.
   7. Do not select TBD in the Personnel drop-down list if personnel are known. They must be first entered in the Project Personnel section as outlined above.
   8. Do not combine personnel on one budget line (e.g., multiple postdocs must be itemized individually).
   9. Provide justification for each budget line item entered, including all Personnel Costs requested. Note that the budget justification should be detailed and appropriate for the funds being requested. An insufficient budget justification will result in the proposal not being considered further.
   10. The addition of subcontract budgets is handled via the Project Personnel section in the Contacts & Personnel tab. Click on the Add/Modify Project Personnel button in that section for additional instructions.
   11. Within each budget period, you have the ability to copy the budget and justification from the previous period and then make edits as needed. Important note: If content has already been entered in year 2 or 3, for example, copying from the previous year will not replace the content — it will only add the previous year’s content, potentially duplicating the budget the next year. Duplicated entries can only be deleted individually by line item.

8. Send for Sign-Off & Submit Application: When each application is complete, each PI and director must click on the Send for Sign-Off button on their respective application to send to their application’s designated signing official for signature. The Signing Official will receive an email from [email protected] notifying them that an application requires their signature. The Signing Official must electronically sign the application via the Submission tab of the application. Once their signature is entered and saved, the Signing Official must click the Submit Signature button. A confirmation page will appear for the Signing Official once the application has been signed. For the director, this will move their application to a status of Signed – Pending Submission and they will receive an email from [email protected] notifying them that the application has been signed but is still pending submission. For a PI, this will submit to the director’s application and move their application to a status of Submitted to Spokesperson PI. They will receive an email from [email protected] notifying them that the application has been submitted to the director/spokesperson PI.
   1. For PIs: After the full proposal application is completed and signed by their signing official, a confirmation page will appear noting it has been successfully submitted to the director/spokesperson PI by the signing official.
   2. For the Director: After the full proposal application is completed and signed by their signing official, a confirmation page will appear noting it has been successfully signed by the signing official. When the director’s application has a status of Signed – Pending Submission and all of the PI applications are completed, signed and have a status of Submitted to Spokesperson PI, the director/spokesperson must click on the Submit Application Package button to submit to the foundation. Please note that the director’s institutional official cannot submit the collaboration package to the foundation — this must be done by the director. A confirmation page will appear once the collaboration package is successfully submitted and the application will appear in the Submitted tab of the Applications and Awards table.
   3. Note that you will not be able to submit any collaboration application or the collaboration package if the deadline has passed.

Once your application has been submitted, the Simons Foundation staff will be in touch if we require any additional information or revisions to your application.
