Dingus is one of 120 members and 30 international members elected by their peers in 2025, joining a select group of 2,662 scientists around the country recognized for their influential research. She’s one of 26 current UMD faculty members in the National Academy of Sciences and is among 75 named to various esteemed honorary academies.

“This is an incredible honor,” Dingus said. “It is a wonderful recognition of the scientific importance of this new area of astronomy. Gamma-ray astrophysics is a very collaborative and interdisciplinary field, and I want to recognize and thank all the excellent scientists with whom I have had the pleasure to work.”

An astrophysicist who studies the highest-energy light from astrophysical sources, Dingus investigates how nature accelerates particles to extremely high energies, producing gamma rays in space that can be detected from Earth. She is best known for her work in developing innovative gamma-ray detectors and analyzing data to understand cosmic phenomena occurring in extreme environments such as around neutron stars and supermassive black holes.

“Brenda has been a true pioneer in particle astrophysics, with a remarkable breadth and depth of contributions that have profoundly shaped the field,” said Distinguished University Professor of Physics Jordan Goodman, a long-time collaborator who has worked with Dingus on several projects including the Cygnus air shower experiment in 1986. That experiment, conducted at the Los Alamos National Laboratory to study the composition and energy of cosmic rays as they interacted with Earth’s atmosphere, laid the groundwork for future studies in the then-emerging field of cosmic and gamma-ray research.

After earning her Ph.D. from UMD in 1988 under the supervision of Gaurang Yodh, she spent seven years at NASA's Goddard Space Flight Center. She then held tenured faculty positions at the University of Utah and the University of Wisconsin before joining Los Alamos National Laboratory as a staff scientist in 2002. Dingus has been a visiting research scientist at UMD since 2020. 

Throughout her career, Dingus led the development of increasingly sophisticated instruments for detecting gamma rays from space and on Earth. Following her doctoral studies in experimental cosmic-ray physics at UMD, she contributed to the development and implementation of several instruments at NASA Goddard, including the Fermi Gamma-ray Space Telescope and its predecessor, the Energetic Gamma Ray Experiment Telescope (EGRET) on NASA’s Compton Gamma Ray Observatory satellite. Because lower-energy gamma rays cannot be detected on Earth’s surface, EGRET was specifically built to detect and gather data on lower-energy gamma rays in space. The project played a crucial role in mapping the Milky Way and detecting blazars (regions found in the center of galaxies that emit extremely powerful jets of radiation) and continues to influence NASA’s gamma-ray research.

Milagro’s successor, the High Altitude Water Cherenkov (HAWC) Observatory in Mexico, has identified more than 100 gamma-ray sources since it began operations in 2015, with Dingus serving as U.S. spokesperson, operations manager and principal investigator of the project. HAWC’s notable findings include the first detections of gamma rays exceeding 100 tera-electronvolts (TeV) and “microquasars,” rare binary star systems in which a black hole orbits a normal star. 

An elected Fellow of the American Physical Society and a Los Alamos National Laboratory Fellow, Dingus was awarded a Presidential Early Career Award for Scientists and Engineers in 2000 and an Honorary Medal from the Mexican Physical Society in 2017. Over her 40-year career, Dingus has co-authored 249 publications, which have garnered over 24,000 citations. Dingus also served on numerous advisory committees to the American Physical Society, NASA, the National Science Foundation and the Department of Energy and currently serves on the Board of Trustees of the New Mexico Museum of Natural History and Science.

Dingus continues to work on cosmic- and gamma-ray instrumentation at UMD, collaborating with Goodman and physics research scientist Andrew Smith on the Southern Wide-field Gamma-ray Observatory. Planned for construction in northern Chile in 2026, the observatory will detect air shower particles produced by gamma rays as they interact with Earth’s atmosphere and study extreme astrophysical phenomena, including gamma-ray bursts and supernova remnants.

Nicole Yunger Halpern, a physicist at the National Institute of Standards and Technology (NIST) who works at the University of Maryland as a Fellow in the Joint Center for Quantum Information and Computer Science (QuICS), has received an Early Career Scientist Award (ESCA) in Statistical Physics for her exceptional work bridging statistical physics, thermodynamics, and quantum information theory.

The award, presented every three years by the C3 Commission on Statistical Physics of the International Union for Pure and Applied Physics, recognizes outstanding achievements and promise for the future careers of young scientists in both theoretical and experimental statistical physics.

Yunger Halpern is one of only three scientists to be named a recipient this year. In awarding her this honor, the selection committee specifically highlighted her fundamental contributions to non-Abelian thermodynamics and her exploration of the relationship between quantum chaos and the work fluctuation theorem in non-equilibrium thermodynamics.

At UMD, Yunger Halpern is a senior investigator in the NSF Quantum Leap Challenge Institute for Robust Quantum Simulation, an adjunct faculty member in the University of Maryland Institute for Advanced Computer Studies and Institute for Physical Science & Technology, and a co-founder of the Maryland Quantum Thermodynamics Hub.

She leads a theoretical research group that is modernizing thermodynamics, which traditionally describes large things like steam engines. Yunger Halpern’s team uses the tools of quantum information theory to make a theory of quantum thermodynamics that describes small things like individual molecules and the qubits that are the basic building blocks of quantum computers. She applies her quantum thermodynamics perspectives to problems from a broad range of fields, including atomic, molecular, and optical physics; condensed matter physics; chemistry; high-energy physics; and biophysics.

Yunger Halpern will accept the award at the 29th International Conference on Statistical Physics, to be held in Florence, Italy July 13–18.

"Capital of Quantum" illustration by Valerie Morgan

Happy Quantum Day!

If that’s a salutation you’re unfamiliar with, this might not be the last time you encounter it. Celebrated every April 14, World Quantum Day seeks to boost understanding and appreciation of quantum science and technology.

It’s especially appropriate at the University of Maryland, the heart of the “Capital of Quantum.” UMD President Darryll J. Pines president coined the term to highlight the university’s role in the region’s ecosystem of research, federal agencies and companies dedicated to exploring mysteries of quantum science and exploiting the power of quantum computing and other technologies. On campus in January, Gov. Wes Moore announced it as a billion-dollar initiative to build on UMD’s expertise in physics, engineering and other aspects of quantum research to grow this burgeoning industry and boost the economy of the state of Maryland while addressing global issues.

Last week, Moore signed into law $52.5 million in funding to kick off the Capital of Quantum initiative; it will support research, education, training, operations and other priorities, as well as help the groundbreaking College Park-based quantum computing company IonQ move into new headquarters in UMD’s Discovery District.

If you’re wondering why quantum science and tech matters to you, read on:

UMD’s not just a top basketball school, it’s a top quantum school.
After our historically strong physics department huddled with the U.S. Department of Commerce’s National Institute of Standards and Technology and the UMD-based Laboratory for Physical Sciences in 2006, the resulting Joint Quantum Institute launched a dynasty: 10 quantum centers and institutes with hundreds of researchers delving into topics ranging from exploration of the quantum foundations of the universe to cutting-edge telecom tech. The university today is renowned as a top center for quantum research, while U.S. News and World Report ranked us No. 2 in the nation among public institutions for graduate education in quantum physics.

UMD is building a quantum business ecosystem, meaning more jobs for Marylanders.
The university’s Discovery District is already home to IonQ—which was spun out of UMD labs as the only publicly traded company focused on quantum computing hardware, software and networking. More companies are following in its wake, some affiliated with a UMD business accelerator, the Quantum Startup Foundry. The private Quantum Catalyzer (Q-Cat) follows a similar model. This rising tide of business creates more economic opportunity locally, contributing to the growth of a major industry of the future rooted in the state of Maryland.

The first wave of quantum tech already revolutionized society.
MRI machines, lasers, even old-fashioned transistor radios—none of these everyday devices would exist without an earlier wave of quantum discovery stemming from the research of scientific giants like Albert Einstein and Neils Bohr. Plus, the defining technology of our age, the computer microchip processor, is fundamentally quantum mechanical.

The next wave of computing will remake society.
Quantum computers, which are still in their infancy (or toddlerhood, anyway), are expected to be able to use counterintuitive aspects of quantum physics to quickly polish off computations that could take modern supercomputers millions or billions of years to finish. The practical upshot of this is expected to be disruptive innovation and upheaval across a range of sectors including health care, banking and transportation.

Quantum could help cure disease.
We may not even need full-scale, general-use quantum computers to open the door to personalized pharmaceuticals and new, life-saving therapeutics. “Quantum simulation”—a simpler variant of quantum computing that uses quantum information processing to study chemical reactions and other phenomena—could supercharge drug development; an institute headquartered at UMD and backed by the National Science Foundation is focused on developing the computer technology that could one day lead to such advances.

Quantum will be central to security discussions of the future.
Current computers can’t crack the public-key encryption that protects everything from your bank account to national secrets—but quantum computers probably will be able to smash through it. That’s why researchers are developing new approaches to “post-quantum cybersecurity”—and even ways to safeguard encrypted data that has already been harvested by malicious hackers hoping to decrypt it once quantum computers are widely available. But not all the news is worrying—the quantum internet of the future, on which UMD researchers are helping to lead development, will be inherently secure, because you can’t eavesdrop on quantum data without destroying it.

Bonus tip: Mind-bending quantum knowledge could make you the star of the party.
You’ll sound like you stepped out of the pages of a French philosophical novel explaining “superposition,” which posits seeming absurdities, like your cat is both alive and dead until you check on it (hopefully it survived the period of quantum uncertainty), or atoms can “spin” two ways at once until a quantum computer measures them. And you’ll woo that special someone like never before with another key concept in quantum information science known as “entanglement,” which links the fates of two particles—or hearts?—across infinite distances.
