Bright, inquisitive young minds join Sandia’s MESA complex through the Student Intern Group for Microelectronics Advancement, known as the SIGMA institute. Interns gain hands-on research experience in growing areas of microelectronics critical to national security, including design and testing, fabrication engineering and packaging. Here, an intern remotely operates a device to test the effect of temperature on brain-inspired computing devices Learn more at bit.ly/3TE0woz Photo by Craig Fritz

A semiconductor is tested to see if it meets specifications at Sandia’s MESAFab complex. Semiconductors power all kinds of products, including smartphones, self-driving cars and AI technologies. Sandia is addressing the nation’s urgent need for semiconductors by becoming the first national lab to join the National Semiconductor Technology Center.

Sandia researchers deployed the world’s first large-scale SpiNNaker2 neuromorphic computing system called NERL Braunfels. Developed with German startup SpiNNcloud, the system houses 175 million digital neurons, comparable to the brain power of a small mammal. Funded by National Nuclear Security Administration's Advanced Simulation and Computing program, the system will support research into how neuromorphic computing can enhance the nation’s most critical nuclear deterrence missions.

Sandia and the nuclear security enterprise have completed the first production unit of the B61-13 gravity bomb about a year earlier than slated. Sandia is the lead systems integrator and design agency for the B61-13’s nonnuclear components. Much of the new system’s configuration builds on the B61-12, which completed production in late 2024.

More than 30,000 visitors, including many Sandia employees, attended an air show at Kirtland Air Force Base, which is also home to the Labs’ New Mexico headquarters. Crowds gathered beneath a Lockheed C-5 Galaxy, one of the largest military aircraft in the world. Behind it, an HH-60W Jolly Green II from Kirtland’s 58th Special Operations Wing took flight.

As a 2025 Sandia Distinguished Fellow, Ravyn Malatesta researches the relationship between light and matter, particularly how the quantum properties of photons change when interacting with materials. During her three-year fellowship, Ravyn will explore using metasurfaces — ultrathin films that support arrays of artificial nanostructures — to generate and control hyperentangled photon states.

Sandia Hruby Fellow Olivia Krohn studies how energy is transferred when molecules collide. Her research tests the accuracy of theoretical predictions about chemical physics. “When two atoms collide, their behavior isn’t so different from tiny billiard balls. However, molecules have shapes and additional motions like rotations and vibrations, which require energy. When two molecules collide, they redistribute that energy in interesting ways that are hard to predict,” Olivia said. Learn more about her research at bit.ly/45aynN4 Photo by Randy Wong

Sandia Truman Fellow Dan Herman uses optical frequency combs — tools that measure light — to evaluate the chemical properties of air. His work connects advanced scientific research and real-world applications that benefit public health. “I believe that the most important science will always keep the human experience in mind,” Dan said. “I feel fortunate to have a career that allows me to study the fundamental nature of matter and light while applying these insights to improve our well-being.” Learn more about his research at bit.ly/4jNsoBt Photo by Craig Fritz

Sandia Truman Fellow Sam Peana constructs a laser enclosure for a confocal time-correlated single photon counting microscope. This microscope will be used to measure the quantum properties of single photon emitters that will be produced in the Microsystems Engineering, Science and Applications facility.

Sandia is restarting the Molten Salt Test Loop after damage from a major storm shut it down in 2017. The MSTL will provide a safe and reliable environment for industries to test components in flowing, molten nitrate salts at temperatures up to 600 degrees Celsius. In the photo, Sandia solar researcher and project lead Kenneth Armijo stands next to the MSTL, the largest laboratory salt test loop in the world.

“I feel like I’ve trained my whole life for this,” said the new Director of Sandia Labs, Laura McGill. McGill stepped into Sandia’s top job in May 2025 after a decadeslong career in nuclear deterrence, sparked by a childhood fascination with science. She’s spent the past month outlining her priorities and charting the course for how the Labs will continue to tackle challenges and deliver results.

Sandia’s Kids Day drew 2,165 visitors to the Labs. Students in grades 5-12 toured facilities, including the Laser Applications Facility, or LAZAP, that awed with its giant laser. Kids also enjoyed demonstrations, interactive activities, games, food and fun. Photo by Craig Fritz

Sandia researchers have developed a sensor that can detect sarin and other chemical warfare agents in milliseconds. The circuit is 1,500 times smaller than a human hair and has a battery that can last nearly a decade. The sensor is designed to protect the public and warfighters by providing a “get out of Dodge” alert and warnings that toxins are present. Learn more at bit.ly/3EvaDIr Photo by Craig Fritz
