Isabelle Snyder calls faults as she sees them, whether it’s modeling operations for the nation’s power grid or officiating at the US Open Tennis Championships.

Eva Davidson, a nuclear engineer at Oak Ridge National Laboratory, is developing modeling and simulation techniques for current and future nuclear reactors.

Like many soon-to-be high school seniors, Eva Davidson thought she knew what she wanted to be and how to get there. A chance encounter at a college fair altered that path—a change in plans she has never regretted.

Stephanie Galanie

Early career scientist Stephanie Galanie has applied her expertise in synthetic biology to a number of challenges in academia and private industry. She’s now bringing her skills in high-throughput bio- and analytical chemistry to accelerate research on feedstock crops as a Liane B. Russell Fellow at Oak Ridge National Laboratory.

Raphaël Hermann of Oak Ridge National Laboratory studies magnetic materials and batteries using Mössbauer spectroscopy.

Raphaël Hermann of the Department of Energy’s Oak Ridge National Laboratory conducts experiments to better understand materials for energy and information applications.

Hong Wang, a senior distinguished researcher at the National Transportation Research Center, uses applied mathematics and modeling to improve transportation systems.

In Hong Wang’s world, nothing is beyond control. Before joining Oak Ridge National Laboratory as a senior distinguished researcher in transportation systems, he spent more than three decades studying the control of complex industrial systems in the United Kingdom.

Sometimes solutions to the biggest problems can be found in the smallest details. The work of biochemist Alex Johs at Oak Ridge National Laboratory bears this out, as he focuses on understanding protein structures and molecular interactions to resolve complex global problems like the spread of mercury pollution in waterways and the food supply.

Organic chemist Santa Jansone-Popova designs new chemical architectures to support chemical separations that lay the groundwork for clean water and energy advances.

An organic chemist at Oak Ridge National Laboratory, Santa Jansone-Popova focuses on the fundamental challenges of chemical separations that translate to world-changing solutions for clean water and sustainable energy.

Oak Ridge National Laboratory’s Chris Petrie assembles a fiber optic sensor, fabricated using additive manufacturing, for measuring dimensional changes. Petrie is developing fiber optic–based sensors that can offer greater insights into how materials, such as fuel cladding, perform during irradiation testing inside ORNL’s High Flux Isotope Reactor.

With operating licenses for nearly all nuclear power plants set to expire in the 2030s and 40s—a pending loss that would affect a fifth of the country’s electricity supply—U.S. utilities will need to find a way to respond to what has been called the “nuclear cliff.”

Veda Galigekere is leading Oak Ridge National Laboratory’s work on fast, efficient, wireless charging of electric vehicles.

Galigekere is principal investigator for the breakthrough work in fast, wireless charging of electric vehicles being performed at the National Transportation Research Center at Oak Ridge National Laboratory.
