With the rise of the global pandemic, Omar Demerdash, a Liane B. Russell Distinguished Staff Fellow at ORNL since 2018, has become laser-focused on potential avenues to COVID-19 therapies.

Ecosystem Ecologist Verity Salmon captures and analyzes field data from sites in in Alaska and Minnesota to inform earth system models that are being used to predict environmental change.

While some of her earth system modeling colleagues at ORNL face challenges such as processor allocation or debugging code, Verity Salmon prepares for mosquito swarms and the possibility of grizzly bears.

In the Physics Division of the Department of Energy’s Oak Ridge National Laboratory, James (“Mitch”) Allmond conducts experiments and uses theoretical models to advance our understanding of the structure of atomic nuclei, which are made of various combinations of protons and neutrons (nucleons).

Kat Royston

As a teenager, Kat Royston had a lot of questions. Then an advanced-placement class in physics convinced her all the answers were out there.

Joe Paddison, a Eugene P. Wigner Fellow at the Department of Energy’s Oak Ridge National Laboratory, believes there’s more information to be found in neutron scattering data than scientists like himself might expect.

Nils Stenvig is modeling the nation’s bulk electric system for DOE’s North American Energy Resilience Model to better understand and predict the grid’s behavior.

Nils Stenvig has always had an interest in solving big problems. That desire drove his focus on electrical engineering in college and eventually led him to Oak Ridge National Laboratory, where today he’s using his expertise to better understand the world’s largest machine—the electrical grid.

To understand the electronic structures of solids and predict their properties, ORNL’s Valentino Cooper uses density functional theory (DFT), which models how many electrons are in a region rather than where those electrons are. “DFT essentially presents one electron existing in a ‘sea foam’ and tells how dense that foam is,” he said.

Valentino (“Tino”) Cooper of the Department of Energy’s Oak Ridge National Laboratory uses theory, modeling and computation to improve fundamental understanding of advanced materials for next-generation energy and information technologies.

Ben Betzler, a reactor physics nuclear engineer at Oak Ridge National Laboratory.

As a reactor physics nuclear engineer, Ben Betzler leverages and develops computational methods to solve questions across nuclear energy—whether it’s finding the best design of a reactor core or repurposing an old tool for a new analysis.
