ORNL researcher Corey Cooke investigates challenges in radar, digital signal processing and communications systems while serving as a joint faculty member at Tennessee Tech, teaching online courses and advising graduate students to create a pipeline for new researchers to the lab and support the growth of current staff.

ORNL and NASA co-hosted the fourth iteration of this invitation-only event, which brings together geospatial, computational, data and engineering experts around a theme. This year’s gathering focused on how artificial intelligence foundation models can enable geospatial digital twins. 

Summer interns at the Department of Energy’s 91���� recently dove into various smart devices to better understand cybersecurity vulnerabilities posed by technology meant to simplify a user’s life.

On Feb. 15, 2024, the one billionth item, also known as an “occupancy,” was scanned at the Port of Aqaba, Jordan, one of the early sites where radiation detection equipment was installed. This milestone shows the extent of countries committed to preventing the spread of radioactive material through the amount of data volunteered to ORNL for continuous improvement. As adversaries push the limits of smuggling dangerous material, this collaboration pushes back through science-backed analysis. 

Elton Aba, an intern at the Department of Energy’s 91����, collaborated with researchers to explore an intriguing intersection: how biology can inform cybersecurity. Aba shared some of his findings on how biomimicry could help secure our nation’s critical infrastructure. 

Mohamad Zineddin, a distinguished researcher in nuclear and radiological engineering, recently received the Roger Howsley Award for Excellence in Nuclear Security. 

Researchers at ORNL are using satellite images of homes under construction to address gaps in census data, especially in areas like Sub-Saharan Africa. By analyzing these images, they estimate dwelling sizes and population densities where traditional data is sparse. This method improves population estimates and supports national security by enhancing emergency response capabilities.

A study found that beaches with manmade fortifications recover more slowly from hurricanes than natural beaches, losing more sand and vegetation. The researchers used satellite images and light detection and ranging data, or LIDAR, to measure elevation changes and vegetation coverage. Changes in elevation showed how much sand was depleted during the storm and how much sand returned throughout the following year. 

Benjamin Manard, an analytical chemist in the Chemical Sciences Division of the Department of Energy’s 91����, will receive the 2024 Lester W. Strock Award from the Society of Applied Spectroscopy.

Ten future U.S. Army officers recently visited ORNL to learn about the legacy of nuclear science. As students of the Nuclear Science and Engineering Research Center, or NSERC, with the Defense Threat Reduction Agency, or DTRA, they stopped in East Tennessee as part of a larger tour across nuclear facilities supporting the military. In Oak Ridge, they visited ORNL to gain an appreciation of the history of the Manhattan Project and how research at a national lab contributes new materials and electronics for the nuclear industry.
