PNNL-Seattle provides a portal to Department of Energy national laboratory staff, facilities, and equipment used to solve some of the nation’s most pressing issues.  

PNNL-Seattle’s presence dates back more than 50 years, when we focused initially on nuclear nonproliferation policy. Today, PNNL-Seattle is home to researchers, analysts, and other subject matter experts spanning the national security, energy, and environmental mission space. 

Together with industry partners and key collaborators, our staff accelerate discovery for 21^st century problems and opportunities in data science, cybersecurity, software engineering, artificial intelligence, energy system engineering, earth and coastal science, nuclear nonproliferation, and more.  

PNNL-Seattle has more than 300 employees, interns, and post-graduate research associates. We leverage our location to increase our mission impact through regional sponsor engagement, research collaboration with private sector and academic institutions, and as a portal for recruiting top talent. Tapping into the region’s innovation hotbed allows us to tackle complex issues at the nexus of science, technology, and policy and grow our capabilities and impact across the Laboratory.
