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...

ORNL researcher Jibonananda Sanyal applies high-performance computing to urban environment challenges.
The first time Jibonananda Sanyal ever logged into a supercomputing system, the landing page told him he could use up to 500 cores, a modest number for some but a significant amount for the early career researcher. “Up until then I had used two cores, at most,” he said. It wou...
ORNL researcher Kate Page developed an early interest in materials science during a college internship.
In 1675, Isaac Newton famously wrote, “If I have seen further, it is by standing on the shoulders of giants." History records that even Newton had help climbing onto those shoulders, which shows the need for forward-thinking scientists who influence tomorrow’s researchers by doing...
Oak Ridge National Laboratory entrance sign

If you ask the staff and researchers at the Department of Energy’s Oak Ridge National Laboratory how they were first referred to the lab, you will get an extremely varied list of responses. Some may have come here as student interns, some grew up in the area and knew the lab by ...

Sergei Kalinin, director of the Institute for Functional Imaging of Materials at Oak Ridge National Laboratory, convenes experts in microscopy and computing to gain scientific insights that will inform design of advanced materials for energy and informati

Sergei Kalinin of the Department of Energy’s Oak Ridge National Laboratory knows that seeing something is not the same as understanding it. As director of ORNL’s Institute for Functional Imaging of Materials, he convenes experts in microscopy and computing to gain scientific insigh...

ORNL researcher Moonis Ally with his published theory: "Thermodynamics of Highly Concentratied Aqueous Electrolytes."
Of all the roles Moonis Ally has held during his life, the title of ‘problem solver’ resonates with him the most. Ally’s commitment to problem solving, and ultimately to helping others solve problems, is what led to the theory bearing his name and the book summarizing his wor...

The materials inside a fusion reactor must withstand one of the most extreme environments in science, with temperatures in the thousands of degrees Celsius and a constant bombardment of neutron radiation and deuterium and tritium, isotopes of hydrogen, from the volatile plasma at th...

Singanallur “Venkat” Venkatakrishnan is a Wigner Fellow in the Imaging, Signals, and Machine Learning Group at ORNL.
Singanallur “Venkat” Venkatakrishnan is helping scientists get a better view of objects under study by some of Oak Ridge National Laboratory’s most powerful instruments by creating algorithms that turn data into 3D renderings with fewer images. The result is a better understanding o...

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...
