I have achieved my Bachelor of Science and Master of Science at Pusan National University. I worked under Dr. Tae-Min Oh on a project funded by the Ministry of Land, Infrastructure and Transport. My research focus was on the particle characteristics analysis of abrasive materials in rock-drilling AWJ (abrasive waterjet), and long-term maintenance & replacement of aging water pipes in utility tunnels. After completing my master's degree, I worked as a full-time research fellow at Pusan National University for six months. My research interests include soft ground improvement, soil behaviors, and artificial intelligence in civil engineering.
