Our science secures the nation
From climate change and cyber attacks to nuclear proliferation and critical infrastructure vulnerabilities, the threats to America’s national security continue to evolve and emerge at a rapid pace. To effectively counter those threats—and protect our nation—we must increasingly turn to science, to the technologies and innovations that underpin our defenses.
The National Security Sciences Directorate is rapidly advancing the science of resilience, security, and analytics to solve critical challenges in nuclear security, cybersecurity, and human security. Our world-leading researchers engage in collaboration across the Laboratory—in areas such as nuclear and chemical sciences, applied materials, advanced manufacturing, biosecurity, transportation, and supercomputing—to protect the nation today while identifying and addressing future threats.
