Chinese Scientist Wins Inaugural ICBS Basic Science Medal
Chinese Academy of Sciences (CAS) Academician Wang Yifang, a leading experimental particle physicist at the Institute of High Energy Physics (IHEP), has been awarded the inaugural ICBS Samuel C.C. Ting Medal in Physics at the 2026 International Congress of Basic Science (ICBS). The award, announced on May 18 at a press conference held at Tsinghua University in Beijing, recognizes Wang’s pioneering contributions to neutrino oscillation research and his leadership in building one of the world’s most advanced neutrino observatories, according to People’s Daily.
Wang shares the physics medal with Prof. Andrea J. Liu of the University of Pennsylvania and Prof. Xiao-Gang Wen of the Massachusetts Institute of Technology. The award places China’s growing influence in fundamental scientific research firmly in the global spotlight.
The Award: A New Global Honor for Basic Science
The ICBS Medal of Basic Sciences was established for the first time in 2026 to honor scientists worldwide who have achieved revolutionary and breakthrough accomplishments in basic science. The awards span three disciplines — mathematics, physics, and engineering — with three medals in each field named after towering figures in scientific history. The physics medals are named after Marie Curie, Samuel C.C. Ting (丁肇中), and David Gross, as IHEP reported.
Notably, each discipline includes a medal named after a prominent female scientist, reflecting the scientific community’s recognition of women’s contributions to science. The medal names were approved by the scientists themselves or their families.
The main ICBS 2026 congress, themed “Advancing Basic Science for Humanity,” is scheduled to take place from August 9 to 21 in Huairou Science City, Beijing. The event will feature nearly 20 plenary speakers including Nobel laureates, Fields Medalists, and Turing Award winners, and is expected to attract close to 1,000 scholars from around the world, according to the Shanghai Institute for Mathematics and Interdisciplinary Sciences.
Wang Yifang’s Pioneering Contributions
The ICBS award citation commends Wang for his “pioneering discovery of a new type of neutrino oscillation and the first precise measurement of the mixing angle θ₁₃” and for leading the construction of the Jiangmen Underground Neutrino Observatory (JUNO), which “aims to determine the neutrino mass ordering and continues to explore new physics beyond the Standard Model.”
Wang’s landmark achievement came in 2012 when the Daya Bay Reactor Neutrino Experiment, which he co-led, made the groundbreaking discovery of a new type of neutrino oscillation — electron antineutrino disappearance — and provided the first precise measurement of the mixing angle θ₁₃. The result was hailed as “the most important physics experiment result ever from China” and fundamentally reshaped the scientific understanding of neutrino oscillation patterns.
Building on this success, Wang led the construction of JUNO, a 700-meter-deep underground facility in Jiangmen, Guangdong Province. The observatory’s centerpiece is a 35.4-meter diameter acrylic sphere filled with 20,000 tons of liquid scintillator, monitored by 45,000 photomultiplier tubes. JUNO began formal operations in August 2025 and published high-precision results within two months, confirming deviations in solar neutrino oscillation parameters.
A Legacy of Scientific Leadership
Wang Yifang is no stranger to international recognition. In 2016, he became the first Chinese scientist to win the Breakthrough Prize in Fundamental Physics. His list of honors also includes the W.K.H. Panofsky Prize from the American Physical Society, the Nikkei Asia Prize, the Future Science Prize, the European Physical Society High Energy and Particle Physics Prize, and the First Class State Natural Science Award.
In an interview earlier this year, Wang emphasized the fundamental importance of basic science: “Basic science is our understanding of nature, and all our applications are ultimately based on this. So without recognizing the laws of nature, so-called applications are also very difficult.” He described satisfying human curiosity and deepening our understanding of nature as “a noble goal, undoubtedly worth pursuing.”
China’s Growing Role in Global Big Science
This award comes at a time when China is making major investments in large-scale scientific infrastructure. JUNO itself is a testament to international collaboration, involving nearly 700 researchers from 74 institutions across 17 countries, with a design life of 30 years.
The ICBS, founded in 2023 by Fields Medalist Shing-Tung Yau, represents a concerted effort to position Beijing as a global hub for international scientific exchange. The naming of the physics medal after Samuel C.C. Ting — a Chinese-American Nobel laureate — creates a symbolic link between generations of Chinese physicists and underscores the growing recognition of China’s contributions to fundamental research.
Implications and What to Watch For
Wang’s recognition strengthens the case for continued investment in basic science in China. He has been a vocal advocate for increased funding, arguing that fundamental research is essential for long-term technological innovation and national competitiveness.
The formal medal ceremony will take place during the main ICBS congress in August 2026, where further details about the award and other medalists are expected to emerge. The scientific community will also be watching closely for JUNO’s upcoming measurements on neutrino mass ordering — considered one of the most important questions in particle physics for the next decade.
As Wang himself noted upon JUNO’s completion: “This is a historic milestone, and it is the first time internationally that such a large-scale, high-precision neutrino-specific major scientific facility has been operated. It will enable us to answer fundamental questions about the nature of matter and the universe.”
With this latest honor, Wang Yifang has not only cemented his place among the world’s foremost experimental physicists but has also signaled China’s arrival as a major force in the global pursuit of fundamental scientific knowledge.
