Intelligent and Interactive Dynamic Systems (IIDS)

NSF's implementation of the revised 2 CFR

NSF Financial Assistance awards (grants and cooperative agreements) made on or after October 1, 2024, will be subject to the applicable set of award conditions, dated October 1, 2024, available on the NSF website. These terms and conditions are consistent with the revised guidance specified in the OMB Guidance for Federal Financial Assistance published in the Federal Register on April 22, 2024.

Important information for proposers

All proposals must be submitted in accordance with the requirements specified in this funding opportunity and in the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. It is the responsibility of the proposer to ensure that the proposal meets these requirements. Submitting a proposal prior to a specified deadline does not negate this requirement.

Updates to NSF Research Security Policies

On July 10, 2025, NSF issued an Important Notice providing updates to the agency's research security policies, including a research security training requirement, Malign Foreign Talent Recruitment Program annual certification requirement, prohibition on Confucius institutes and an updated FFDR reporting and submission timeline.

Synopsis

Supports fundamental research to advance the science and engineering of intelligent dynamic systems, including engineered systems that interact with people.

The world around us, from living organisms and natural environments to machines and structures, can be described using the language of dynamic systems. Dynamic systems are networks of interconnected components whose behavior changes in time. Research on dynamic systems seeks to understand how their behavior can be predicted and influenced when important aspects of the system are hidden or unpredictable. IIDS invests in fundamental research that impacts national priorities in the context of dynamic systems and improves quality of life.

The IIDS program supports transformative ideas that advance the science and engineering of intelligent dynamic systems to ensure functionality, safety, reliability, and resilience. Intelligence includes a broad class of methods to solve problems or make decisions. IIDS projects may investigate novel dynamic phenomena and new methods for modeling, simulation, analysis, inference, and control. IIDS also supports the study of engineered systems that interact with and adapt to people. Models of human perception, action, cognition, behavior, and social responses may be created for use in engineered systems. The program supports research that creates innovative theoretical, computational, and/or experimental approaches. The program encourages novel strategies inspired by other disciplines and paradigms for transformative results that are grounded in theory.

Partnerships: To speed discovery and innovation, NSF partners with federal agencies, industry, international groups, and others. Current opportunities are at NSF ENG Partnerships.

This program advances NSF’s mission as given in the NSF organic statute (42 U.S.C. 1861, et seq.).
