The Interagency Rehabilitation and Disability (IRAD) Research Portfolio is a searchable database of government funded research projects in the areas of disability, independent living, and rehabilitation research. IRAD is an interagency initiative headed by the National Institute on Disability, Independent Living, and Rehabilitation Research, in partnership with the National Institutes of Health, the Centers for Disease Control and Prevention, the National Science Foundation, the Department of Defense, and the Department of Veterans Affairs. The purpose of IRAD is to provide a publicly available resource that enables analysis of the federal research portfolio in disability, independent living, and rehabilitation research. This will aid in collaboration and coordination of research activities across federal agencies, as well as increase transparency and visibility for the public and legislative stakeholders.
