Chelsea Chen, a polymer physicist at ORNL, is studying ion transport in solid electrolytes that could help electric vehicle battery charges last longer.

Leah Broussard leads a study of neutron decay to understand correlations between electrons and antineutrinos as well as subtle distortions in the electron energy spectrum.

Leah Broussard, a physicist at the Department of Energy’s Oak Ridge National Laboratory, has so much fun exploring the neutron that she alternates between calling it her “laboratory” and “playground” for understanding the universe. “The neutron is special,” she said of the sub...

Yu collaborates on the MAJORANA DEMONSTRATOR, which set the stage for a future experiment to search for the signal of neutrinoless double-beta decay. Single beta-decay—in which a proton becomes a neutron and emits an antineutrino and a fast-moving electro

Chang-Hong Yu of the Department of Energy’s Oak Ridge National Laboratory fell in love with running in 2008 and has since completed 38 marathons or longer-distance races. Her passion for long-distance races serves her well chasing neutrinos—electrically neutral subatomic particles th...

Amy Moore is a postdoctoral researcher in the Transportation Planning and Decision Science Group at ORNL.

Amy Moore has found that her pursuit of several degrees and certificates in a variety of subjects is serving her well as she uses her expertise in transportation planning, geographic information science, and information technology to develop intelligent mobility solutions at ORNL. ...

Oak Ridge National Laboratory researcher Arnab Banerjee has charted several accomplishments in his neutron studies of quantum phenomena.

Raman. Heisenberg. Fermi. Wollan. From Kolkata to Göttingen, Chicago to Oak Ridge. Arnab Banerjee has literally walked in the footsteps of some of the greatest pioneers in physics history—and he’s forging his own trail along the way. Banerjee is a staff scientist working in the Neu...
