PNNL biodefense experts seek to identify, understand and mitigate the risks of biological pathogens—whether naturally occurring or intentionally created—so steps can be taken to prepare and respond.

Researchers are developing and deploying solutions to reduce risk and increase efficiency while keeping people and the environment safe.

Scientists are studying tiny subatomic particles that pass through humans and possess clues about the origins of the universe.

Tomorrow’s scientific leaders gain real-world experience contributing to PNNL’s research and development.

Despite the challenges, the talented and dedicated staff at Pacific Northwest National Laboratory kept delivering for the nation.

Here at the Department of Energy's Pacific Northwest National Laboratory, much of our physics research focuses on fundamental scientific discovery and national security.
