As leader of the RF, Communications, and Cyber-Physical Security Group at Oak Ridge National Laboratory, Kerekes heads an accelerated lab-directed research program to build virtual models of critical infrastructure systems like the power grid that can be used to develop ways to detect and repel cyber-intrusion and to make the network resilient when disruption occurs.

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...

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...

Shaheen Dewji, radiological scientist in the Center for Radiation Protection Knowledge within the Environmental Sciences Division at ORNL.

Having begun her career at the lab in the nuclear nonproliferation and radiation safeguards area, Shaheen Dewji is leveraging her expertise to help expand the work of the Center for Radiation Protection Knowledge (CRPK)—a unique organization led by Oak Ridge National Laboratory that ...

Oak Ridge National Laboratory researcher Halil Tekinalp combines silanes and polylactic acid to create supertough renewable plastic.

A novel method developed at Oak Ridge National Laboratory creates supertough renewable plastic with improved manufacturability. Working with polylactic acid, a biobased plastic often used in packaging, textiles, biomedical implants and 3D printing, the research team added tiny amo...

ORNL researcher Miaofang Chi refines her microscopy techniques toward understanding how and why materials have certain properties.

Material surfaces and interfaces may appear flat and void of texture to the naked eye, but a view from the nanoscale reveals an intricate tapestry of atomic patterns that control the reactions between the material and its environment. Electron microscopy allows researchers to probe...
