THE 2025 JEAN-MARIE DUBOIS AWARD
The 2025 Jean-Marie Dubois Award
The Jean Marie Dubois Award was established to recognize important, sustained research on any aspect of quasicrystals within the 10-year period preceding the award. The award consists of a cash prize and a plaque, and is made possible by an endowment administered by the Iowa State University Alumni Foundation. The International Advisory Board of the 16th International Conference on Quasicrystals is pleased to announce that the recipient of the 2025 Jean Marie Dubois Award for Excellence in Quasicrystal Research is Prof. Ryuji Tamura.
Ryuji Tamura, Professor at Tokyo University of Science, Japan, will receive the Jean Marie Dubois Award in recognition of his outstanding achievements in establishing the long-range magnetic orderings in periodic approximants and quasicrystals, with the recent discovery of ferromagnetic and antiferromagnetic orders in Tsai-type icosahedral quasicrystals.
Prof. Ryuji Tamura received his PhD in Engineering at the University of Tokyo in 1998 with early works on the electrical properties of quasicrystals. He then worked as a research assistant, lecturer, and associate professor in the Department of Materials Science, Tokyo University of Science, and now he is a full professor in this University since 2015. He has made remarkable achievements in the field of quasicrystalline research, including studies of phase transitions in Tsai type approximants and the discovery of long-range magnetic order in Tsai-type icosahedral quasicrystals and periodic approximants.

Jean-Marie Dubois is an emeritus director of research at CNRS, France, and a scientific adviser at Jozef Stefan Institute (JSI), Slovenia. His research focuses on complex metallic alloys (CMA), particularly quasicrystals, where he has made major contributions. He has explored applications of quasicrystalline alloys in industries such as aviation, developing low adhesion coatings and thermal barriers. As the coordinator of the CMA network of excellence, he played a key role in establishing the topic in Europe. Dubois founded the Institut Jean Lamour, the largest materials science laboratory in France, and has authored books and approximately 400 Journal articles. He has delivered numerous invited talks worldwide and received many awards, honorary degrees, and honorary memberships for his contributions to science.
