Research Activities
In a multiphysics simulation, it is important to consider interaction models on the interfaces of displacement fields, temperature fields, electromagnetic fields, etc. In order to support development/manufacturing of industrial products and predict the diffusion effect, I will extend this modeling and study an interaction modeling approach on the interfaces of simulation technologies used in different disciplines, such as mechanical systems, social systems, and information systems.

Future Plan
I hope to proceed with multidisciplinary studies on the integration of technologies in physics simulation, social simulation, and knowledge information processing.
Messages to Students
By using High Performance Computing technologies effectively, let's integrate different disciplines, such as mechanical systems, social systems, and information systems, and create a novel simulation model that can predict the human environment together. It is important to think outside the box of the conventional discipline.
