Byoungkwan Kim is currently pursuing a Ph.D. in the Division of Advanced Nuclear Engineering (DANE) at Pohang University of Science and Technology (POSTECH) in South Korea. Under the guidance of Professor Wooyong Um, he also had the opportunity to work as a visiting researcher with the Sustainable Materials research team at Sheffield under the supervision of Dr. Brant Walkley. 

During his research visit, Byoungkwan primarily engaged in the application of solid-state magic angle spinning nuclear magnetic resonance to delve into the mechanisms of boron and cesium retention in geopolymer waste forms. His doctoral research centers on the immobilization of various radioactive materials, including borate waste, ion exchange resins, and acidic liquid waste. By utilizing alkali or acid-activated geopolymer waste forms, he aims to develop effective methods for their safe disposal. 

Beyond this, Byoungkwan's interests extend to exploring diverse approaches for radioactive waste disposal, particularly focusing on hydrated waste forms and the retention of radioactive oxyanions. His work underscores a commitment to advancing the field of nuclear engineering and waste management for sustainable solutions.
