ORNL’s Sarah Cousineau is responsible for overseeing and coordinating beam physics research efforts for the Spallation Neutron Source accelerator.
Accelerator physicist Sarah Cousineau has dedicated her career to unraveling the world’s mysteries through physics. A large part of solving those mysteries, she says, means getting the next generation of physicists ready for the same challenge. Cousineau is a group leader in th...
ORNL researcher Xiaobing Liu  works in the laboratory’s Building Technologies Research and Integration Center.

As a boy growing up in China, Xiaobing Liu knew all about Oak Ridge and the World War II Manhattan Project. He had no idea that he would one day work at DOE’s Oak Ridge National Laboratory, the Secret City’s successor. Liu is a lead researcher in geothermal heat pump (GHP) techn...

Melissa Allen’s work at Oak Ridge National Laboratory is focused on urban infrastructure and atmospheric transport, creating models to determine the effects of temperature and climate changes on human activity.
Melissa Allen, a researcher at the Department of Energy's Oak Ridge National Laboratory, is guided by her curiosity and is inspired to pursue what she loves – music, flying and climate science. And she credits her family and many mentors who have helped her along the way. Gro...
Dianne Bull Ezell enjoys the variety of projects offered in a national laboratory setting.
Dianne Bull Ezell has always been a problem solver. As a child she built a bridge of Lego pieces for fun. Nowadays the Electrical & Electronics Systems Research Division engineer has grown from configuring toys to piecing together engineering solutions, and she’s still havin...
Emilio Ramirez studies the slugging transition in a bench scale reactor made possible by the Computational Pyrolysis Consortium, a multilaboratory collaboration formed to develop infrastructure ready fuel from biomass feedstock.

Just a few years ago, Emilio Ramirez spent his days operating and adjusting settings to optimize thermal performance at a Central California bioenergy power plant. Ramirez, a California native who is now a University of Tennessee doctoral candidate working with the Department of...

Diana Hun likes ORNL's state-of-the-art facilities and range of expertise.

When Diana Hun left her home in Panama City, Panama, to attend school at the University of Texas in Austin, she knew she wanted to be an engineer. Exactly which branch of engineering to pursue was not quite as straight-forward. Hun studied both mechanical and electrical engin...

Theoretical condensed matter physicist Cristian Batista brings advanced knowledge of theory to expand upon the experimental physics research conducted at ORNL. (Image credit: Genevieve Martin)
Theory and experiment push each other to expand the frontiers of physics. Now, the Neutron Sciences Directorate at the Department of Energy’s Oak Ridge National Laboratory has both. Cristian Batista, a theoretical condensed matter physicist with a joint appointment at ORNL and th...
As a doctoral student Susan Hogle interned at ORNL's Radiochemical Engineering Development Center.
Susan Hogle has spent the last several years working to improve the production of radioisotopes, particularly californium-252. But not long ago, the native of Napanee, Canada, was working on the opposite task—researching how to dispose of nuclear material. “At Chalk River Laborat...
