Prof. Ho Jin Ryu
Ho Jin Ryu is a Professor in the Department of Nuclear and Quantum Engineering at the Korea Advanced Institute of Science and Technology (KAIST). He has made significant contributions to the field through the publication of 169 international journal articles and the registration of 71 patents. His work spans several areas, including high entropy alloys, refractory materials, metal and ceramic matrix composites, oxide dispersion strengthened alloys, nanocomposites, nuclear fuel, and radioactive waste forms.
Currently, Prof. Ryu leads the Nuclear Fuel Materials Laboratory at KAIST. Before joining KAIST’s faculty in the Department of Nuclear and Quantum Engineering in 2013, Dr. Ryu dedicated 13 years to serving as a senior and principal researcher at the Korea Atomic Energy Research Institute (KAERI). His research there covered advanced materials and processing technologies for nuclear fuel, nuclear fuel cycle, and medical radioisotope production. His tenure at KAERI included periods as a visiting scholar at the Argonne National Laboratory (ANL) in Illinois, USA, from 2005 to 2007, and at the International Atomic Energy Agency (IAEA) in Vienna, Austria, from 2009 to 2011. He earned his B.S., M.S., and Ph.D. degrees in materials science and engineering from KAIST.

Prof. José Manuel Torralba
I am Professor of Materials Science and Engineering in the Department of Materials Science and Engineering at the Universidad Carlos III de Madrid (UC3M) and DIRECTOR OF IMDEA Materials Institute. I am leader of the Powder Technology Group (UC3M)and Powder Sustainable Technologies group (IMDEA Materials). Fellow in the two most important Powder Metallurgy associations in the world: FAPMI and FEPMA (first European to be Fellow at the same time in Europe and USA). FEMS Gold Medal. Ivor Jenkins (IOM3) Gold Medal. I have participated in more than 80 International Advisory Committees at International Conferences, in about 35 competitive funded projects (among which five EU-projects and one NSF-USA project) and in several research evaluation panels (including the EU Research Framework Programmes) some of which in Israel and New Zealand. Throughout my career, I have constantly striven for a holistic approach, being involved in a wide number of academic activities: teaching, research, innovation, university management and management of research programmes and science communication. I have regularly participates in activities related to mentoring, research integrity, new ethics in science and to the promotion of healthy conditions in research labs. I have been an active supervisor of PhD students (29 thesis supervised) and have created a good international network of former students in academia and industry. I also collaborates regularly with NGOs.

A New Approach to Processing of Metal Nanopowder Feedstock for
Additive Manufacturing

Prof. Jai-Sung Lee
Professor Jai-Sung Lee received his PhD from the University of Stuttgart in 1983 while working at the Powder Metallurgy Laboratory of Max Planck Institute for Metal Research. Prior to that, he studied Materials Science at Hanyang University (BS, MS 1977) and KAIST (MS 1979). Since 1983, he has been a professor at Hanyang University, where he not only led National Research Lab (2001) and National Center for Nanoparticle Materials Process Research (2002), but also was actively involved in administrative service as vice president of Hanyang university (2015).
His research focuses on processing of eco-friendly metal nanopowders with bimodal structures developed by his group and elucidating the fundamental issues on powder fabrication, sintering processes based on grain boundary (GB) kinetics, and powder feedstock design for net-shaping processes. He was the first to discover that sintered microstructures have a hierarchical structure demonstrating that GB diffusion differently occurs along two boundaries. In recognition of these achievements, he received the Werner-Koester Prize for the best paper from the German Materials Society in 2002. Recently, he identified the mechanism of activated sintering of tungsten powder based on the correlation of GB diffusion and GB phase transition (IJMR 2024). He is currently studying on the application of bimodal nanopowder feedstocks in AM technologies as well as the GB kinetics of tungsten and HEM alloys.
In addition to his achievements (more than 250 journal articles, 200 proceedings, 5 edited books, 28 patents), he achieved three representative industrial applications; (1) carbon brushes for automobiles with Mando Machinery (1993), (2) MPP soft magnetic core with Samsung Electro-Mechanics (1995), (3) low-alloy iron powder using nanopowder technology with Hyundai Steel (2012). Besides, he has also been a fellow of the Alexander von Humboldt Foundation since 1986 and served as President of the Korean Powder Metallurgy Institute (2007), director of board of Korea Research Council for Fundamental Science and Technology (2006). He has also served as an advisory professor at Samsung Electro-Mechanics R&D (1993-96), Kia Motors (1993), Samsung Corning (2001), and Hyundai Steel (2012). He chaired several national committees for science and technology, including the IR52 Jang Youngsil Prize Committee (2018-21). Currently, he is a senior member of the National Academy of Engineering of Korea. Since 2021 he has been supporting education and R&D policies and managements as a director of board of the Hanyang Foundation.
