Physics Professor Recalls Role in Nobel-Winning IceCube Neutrino Observatory Research

EAST GREENSBORO, N.C. (Nov. 12, 2026) – North Carolina Agricultural and Technical State University Assistant Physics Professor Athina Meli, Ph.D., is celebrating a milestone for neutrino astronomy with the 2026 Nobel Prize in Physics awarded to Francis Halzen, Ph.D., principal investigator of the IceCube Neutrino Observatory.

Meli is a former member of the international IceCube Collaboration, which uses detectors embedded deep in Antarctic ice to study neutrinos. These elusive particles travel vast distances and offer clues to some of the universe’s most energetic events.

Because neutrinos rarely interact with matter, detecting them requires an enormous instrument. IceCube uses thousands of light sensors deep beneath the South Pole to register the faint flashes produced by those rare interactions. Unlike charged cosmic rays, neutrinos travel across space without being deflected by magnetic fields, offering scientists valuable clues about where some of the universe’s most powerful particle accelerators may be found.

“It is particularly rewarding to see this groundbreaking international scientific collaboration recognized at the highest level,” said Meli. “Dr. Halzen’s leadership helped open a new window into the high-energy universe, and I am grateful to have contributed to the collaboration’s scientific work.”

Meli co-authored numerous IceCube scientific publications, including the landmark 2014 Physical Review Letters article, “Observation of High-Energy Astrophysical Neutrinos in Three Years of IceCube Data,” which provided compelling evidence for the existence of high-energy neutrinos originating from astrophysical sources.

Through IceCube related research, Meli also mentored graduate students at TU Dortmund and Ghent University on processes that produce high energy neutrinos. She co-supervised a doctoral student, now a professor in Germany, and a master’s student whose research on hadronic shock acceleration won Belgium’s national first prize in 2015.

At N.C. A&T’s College of Science and Technology (CoST), Meli brings this expertise to teaching, research and student mentorship, helping prepare the next generation of scientists. She continues to study cosmic-ray acceleration, astrophysical jets and energetic processes around supermassive black holes. Her current research connects with the growing field of multimessenger astrophysics, which draws on cosmic rays, neutrinos and light to investigate the most powerful phenomena in the universe. Additionally, she has mentored student researchers since 2022 and received the university’s Provost’s Award for Faculty Excellence in Undergraduate Research Mentoring in 2024.

‘’Dr. Meli’s international research experience and contributions to the IceCube Collaboration exemplify the caliber of scholarship and global engagement we strive to foster at the College of Science and Technology,” said CoST Dean Abdellah Ahmidouch, Ph.D. “Her work creates opportunities for our students to engage in cutting-edge research and reinforces our commitment to research excellence and student growth.”
