UKRI/DisCouRSE Network+

£15,000

Deadline: 5th June 2026, 16:00 BST

“The DisCouRSE Network+ project aims to encourage and support the development of leaders of all kinds across all digital Research Technical Professional (dRTP) roles, primarily within the UK, resulting in an empowered and connected community equipped to shape the future of digital research. We have a twin focus on leadership training and dRTP career pathways – preparing the next generation of leaders and ensuring roles exist for them to lead within.

Our flexible fund supports community-led projects aligned with this goal, enabling aspiring leaders to trial approaches to enhancing skills and career opportunities within their local contexts, build new connections through joint initiatives, and strategically assess options for future investment and activity.”

Eligibility
Applicants must be either resident in the UK, or be employed by an overseas research organisation approved by STFC as eligible to apply for research grant funding. Project leads and co-leads do not need to be academic members of staff. The application must be led by an employed member of staff in a UK-based organisation

Each Coordination Hub Award will receive support of $1M/year for three years, with the possibility for one additional year of support if the Coordination Hub can demonstrate a compelling need as it phases out or transitions to other sources of funding.

Deadline: Letter of intent required; Due June 16, 2026

TechAccess: AI-Ready America is a national-scale initiative to accelerate Artificial Intelligence (AI) readiness and adoption across the U.S. by strengthening coordination, leveraging partnerships and resources, filling gaps, and scaling what works — so local and state priorities can lead in shaping an AI-driven economy that benefits all Americans. Unlike initiatives centered around K – 16 education, AI-Ready America additionally reaches businesses, public-serving organizations, and individuals, among others, expanding access to AI knowledge, tools, and resources. The program also emphasizes practical implementation through hands-on assistance and workforce up-skilling, including experiential learning such as internships, project-based work, and apprenticeships, to ensure stakeholders can effectively apply and innovate with AI.

The program supports:

  1. State/Territory Coordination Hubs (Coordination Hubs) – one in every state, the District of Columbia (DC), or territory in the United States – connecting partners, strengthening planning and deployment, and rapidly scaling approaches;
  2. A National Coordination Lead (National Lead) – facilitating collaboration and knowledge sharing among Coordination Hubs, coordinating priority economic sectors, and informing national AI strategies; and
  3. AI-Ready Catalyst Award Competitions – a series of topic-driven competitions issued over the course of the program to pilot and scale innovative approaches that address critical national AI readiness needs.

This funding opportunity focuses on Coordination Hubs. The National Lead will be funded as an Other Transaction (OT) offered through an Other Transaction Agreement Solutions Offering. AI-Ready Catalyst Award Competitions will be announced through an NSF-approved mechanism, with proposals submitted according to the instructions provided at the time of announcement.

Eligibility
The categories of proposers eligible to submit proposals to the National Science Foundation are identified in the NSF Proposal & Award Policies & Procedures Guide (PAPPG), Chapter I.E. Unaffiliated individuals are not eligible to submit proposals in response to this solicitation.

Deadline: Concept note: 2026-09-07 · Full proposal (by invitation): 2026-11-01

Formerly the Information Controls Fellowship Program, ICRP funds applied research into how authoritarian governments restrict the free flow of information, cut access to the open internet, and implement censorship and surveillance — and the ways these threats to internet freedom can be countered. Projects should include a technical component or output and are reviewed in a two-stage concept-note-then-full-proposal process.

Eligibility
Open to students at any level and to junior- to mid-career practitioners, including those unaffiliated with an academic institution. Typical backgrounds include computer science, engineering, information security, software development, social sciences, and data visualization. Applicants from the majority world and those with experience living in repressive environments are especially encouraged. Researchers embed with a host organization for the duration of the project.
