SEOUL, December 05 (AJP) - The Korea Advanced Institute of Science and Technology said on December 5 that Professor Choi Won-ho of the Department of Nuclear and Quantum Engineering has received the K-T Rie Award at the Asian-European Conference on Plasma Surface Engineering, known as AEPSE 2025, one of the leading global gatherings in applied plasma science and engineering.

The K-T Rie Award is presented every two years to an international researcher who has made notable contributions to applied plasma science. The prize was established in 2015 in honor of Kyong Tschong Rie, a Korean-born plasma surface engineering scholar who worked in Germany.

The Asian-European Conference on Plasma Surface Engineering (AEPSE) brings together researchers from the Asian Joint Committee for Applied Plasma Surface Engineering (AJC-APSE) and the European Joint Committee for Plasma Ion Surface Engineering (EJC/PISE). Held biennially, it serves as a major forum for sharing advances in plasma surface engineering across Asia and Europe.

The Korea Advanced Institute of Science and Technology (KAIST) said Professor Choi has earned international recognition for research that clarifies the physical and chemical processes occurring at plasma–liquid interfaces. His team developed a plasma imaging diagnostics technique that observes the generation of reactive species and energy transfer in real time, helping to identify the core mechanisms behind interfacial reactions.

Choi has also translated basic research into commercial applications. He helped establish Plasmapp, a low-temperature plasma technology company now listed on KOSDAQ. The company develops plasma sterilizers and bio-plasma products. In the space sector, he and his students created Cosmo Bee, a startup focused on plasma-based electric propulsion. Its work contributed to a cube satellite equipped with a plasma Hall thruster that flew on the fourth launch of the Nuri rocket.

Choi has additionally spent a decade on the science and technology advisory committee of the International Thermonuclear Experimental Reactor (ITER) project in Cadarache, France. He has also served on editorial boards and organizing committees of several international journals and conferences in the field.

"It is an honor to receive the K-T Rie Award, which signifies renewed recognition of Korea's competitiveness in plasma research," Choi said. He added that KAIST's environment for interdisciplinary work has supported his progress and that he plans to continue expanding plasma science and its applications.
