NSF Pathways to Enable Secure Open-Source Ecosystems (NSF PESOSE) program

The U.S. National Science Foundation invites you to attend an introductory webinar for the NSF Pathways to Enable Secure Open-Source Ecosystems (NSF PESOSE) program. 

The NSF PESOSE program is a new funding opportunity from the NSF Directorate for Technology, Innovation and Partnerships that combines the former Pathways to Enable Open-Source Ecosystems and Safety, Security, and Privacy of Open-Source Ecosystems programs.  

The PESOSE program helps translate open-source research products, including software, hardware, machine learning models, languages and data platforms, into safe and sustainable ecosystems that address national and societal challenges. The program also promotes strong governance, collaborative development, and broad engagement across academia, industry and government. Additionally, the program aims to enhance the safety, security, and privacy of open-source ecosystems by addressing key vulnerabilities and improving resilience against threats.

Over the course of three webinars, an NSF program director will introduce the program, explain its goals and eligibility requirements, answer questions, and outline the application process. The first webinar session will include a formal presentation followed by a moderated Q&A. A second session will be devoted primarily to open Q&A, giving participants plenty of time to ask their specific concerns. The final session will focus on the application process itself and walk attendees through what to expect. 

To learn more, visit the PESOSE website and review the funding opportunity. If you have any questions, please submit them on the registration page when you register for the webinar or email them to PESOSE@nsf.gov with the subject line "Webinar 1 Inquiry." 

We invite you to share the Zoom link with colleagues you think may be interested in attending the webinar and to subscribe to the PESOSE mailing list for future updates.
