Advancing understanding of the subatomic matter of the universe

We are composed of people with a broad base of skills exploring both fundamental physics questions and practical applications of nuclear and particle physics. Our group includes scientists, engineers, technologists and technicians, postdoctoral researchers, and graduate, undergraduate, high school student interns, and support personnel.


We lead or play a major role in large-scale collaborations with physicists from universities and institutions around the world, performing experiments at world-class facilities, including the following:

  • The search for the quark-gluon plasmaat Brookhaven National Laboratory’s Relativistic Heavy Ion Collider. Search for gluon saturation in nuclei at the Large Hadron Collider. Development of a jet and heavy flavor physics program at the Electron Ion Collider (EIC).
  • The quest for sterile neutrinos at Fermi National Accelerator Laboratory using the MiniBoone experiment and at LANSCE using the Captain-Mills experiment
  • The measurement of the neutron electron dipole moment, which will run at Oak Ridge National Laboratory’s Spallation Neutron Source
  • The study of neutron decay and the neutron electric dipole moment at the Laboratory’s Ultracold Neutron Source facility in order to examine the fundamental properties of matter.
  • Radiography of dynamic materials in real time using the Laboratory’s LANSCE accelerator
  • The use of naturally produced muons from cosmic rays to image the interior of structures and detect the smuggling of nuclear materials
  • Quark energy loss and proton spin structure studies at Fermi National Accelerator Laboratory
