Pacific Northwest National Laboratory


The Nuclear Physics, Particle Physics, Astrophysics, and Cosmology (NPAC) Initiative at Pacific Northwest National Laboratory (PNNL) enables a program of discovery in fundamental nuclear physics and particle physics. An overarching goal of the NPAC Initiative is to expand our research programs within the Department of Energy’s Office of Science and to have PNNL, as an institution, viewed as a leader in fundamental nuclear physics and particle physics.


Learn more about the five intertwined Science Drivers that provide compelling lines of inquiry and show great promise for discovery.


The NPAC consists of a team of nearly 40 staff, to include physicists, chemists, data scientists, technicians, and support professionals.  Our organizational chart:
