For more than 20 years, I have been working on planning, managing, and carrying out many challenging engineering research projects in diverse fields, such as ocean, renewable, biomechanics, disaster, safety, and climate change. Especially, I am specialized in solving various mechanics related and multidisciplinary problems using numerical methods such as finite element method and neural network. Since I have broad backgrounds and experiences in diverse fields, I am ready for solving various disaster, safety related complex problems that requires multidisciplinary knowledge and insight.
