Eugene Mamontov’s background in both basic and applied science has made him a valued partner for scientists who come to the Spallation Neutron Source at ORNL in search of a better understanding of the water dynamics in their research—projects as diverse as studying plant cellulos...
David Weston

David Weston became fascinated with plant genetics and ecology in college, and now with the support provided by the DOE Office of Science Early Career Research Program, he will link those fields as he studies plant-microbe symbiosis. The research will focus on sphagnum moss, a dominant plant of n...

Rose Ruther

In the quest for better batteries, Rose Ruther has found that the positives nearly always outweigh the negatives, and that’s what keeps her coming back to the lab. Ruther works on novel materials to create batteries with higher energy density at a lower cost as part of the Roll to Roll Manufactur...

Oak Ridge National Laboratory researcher Ho Nyung Lee regards his research in novel materials as a “career hobby.”
Some hobbies, like woodworking, require a careful eye for planning and construction. Others, like building a ship in a bottle, need a steady hand and utmost precision.
Adam Witt
Adam Witt’s career path has followed some twists and turns, much like the rivers he studies. But the diversity of his professional experience is a boon to his work as he looks for new ways to harness an ancient energy source: water. Witt, a hydropower systems research engineer,...
