## What this funds

…IS includes the following R&D Improvised Explosive Device Precursor: This was an initiative by which CISA, in a cooperative effort with our domestic and international partners, scientifically assesses and quantifies the threat posed by an array of improvised explosive device precursor chemicals. The IED Precursor R&D was associated with the dedicated Bombing Prevention program proposed for elimination in FY 2027. Technical Forensics: This program advances technological capabilities to characterize and identify the nature, origin, and history of CBRNE materials interdicted before a detonation rapidly, accurately, and credibly. The Office of Countering Weapons of Mass Destruction (CWMD) supports the National Nuclear Forensics Expertise Development program under 6 U.S.C. § (12) that addresses the enduring challenge of sustaining a preeminent workforce of scientists and policymakers that are educated and trained in CBRNE forensics-related specialties by funding undergraduate scholarship, postdoctoral technical fellowships, faculty research awards, and Federal expertise development courses.
