Oak Ridge National Laboratory researcher Ho Nyung Lee regards his research in novel materials as a “career hobby.”
November 6, 2017 – 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.
November 1, 2017 - 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.
ORNL’s Michael Hu is the team lead for thermochemical processing under the DOE Bioprocessing Separations Consortium, leading scientists from eight national laboratories as they develop technologies  to reduce the cost of expensive catalysts.
October 26, 2017 – Chemical and biomolecular engineer Michael Hu has spent his career devising novel means to filter, separate, and select desirable materials from liquids and gases with an eye toward better biofuels, biochemicals, pharmaceuticals, and other products—and is setting his sights on applying the technology to clean water research.
Chengyun Hua applied for a Liane B. Russell Distinguished Early Career Fellowship after meeting ORNL researchers at a Society of Women Engineers conference.
October 13, 2017 – In Chengyun Hua’s research, everything revolves around heat and how it moves. As a Russell Fellow at the Department of Energy's Oak Ridge National Laboratory, Hua carefully analyzes nanoscale heat transfer mechanisms using laser spectroscopy.
October 3, 2017 - For many scientists and engineers, the first real test of their mettle comes not in a classroom, but in a lab or the field, where hands-on experience can teach volumes. For Susan Hogle, that hands-on experience just happened to be with material that was too hot to handle—literally.

September 22, 2017 – Michelle Baldwin’s engineering work has taken her from the public to the private sector and back again, although it was not certain early in her academic career that she would pursue a technical field at all.
Niyanth Sridharan's research at Oak Ridge National Laboratory has contributed to understanding the unexpected behavior of irradiated alloys.
September 13, 2017 – Niyanth Sridharan grew up in a family that indulged his questions by using real-world examples to explain scientific concepts. That natural curiosity still drives the materials researcher today as he explores additive manufacturing techniques at the Department of Energy's Oak Ridge National Laboratory.
Arjun Shankar
September 5, 2017 — The field of “Big Data” has exploded in the blink of an eye, growing exponentially into almost every branch of science in just a few decades.
Computational climate scientist Salil Mahajan simulates the complex and chaotic aspects of climate at Oak Ridge National Laboratory.
August 30, 2017 – Simulating the global climate in high resolution at multiple scales will help answer questions about future global and regional climates. However, as performance expectations increase for Earth system models, so do computing challenges.
Mindy Clark with a crop of more than 5,000 Populus plants in an ORNL greenhouse.
August 23, 2017 – Mindy Clark’s enthusiasm for plant biology has only grown from her time in the classroom at the University of Tennessee, Knoxville (UTK) to her years working in greenhouse operations for private industry and more recently at the Department of Energy's Oak Ridge National Laboratory.
