## Summary

The Department of Mathematical Informatics conducts research and education on the foundation of informatics, with emphasis on the knowledge and skills of data analytics and mathematical modeling to analyze both natural and social phenomena. With the rapid development of information technology, such as the expansion of the Internet, the popularization of mobile devices, the improvement of measurement technologies as well as computer performance, society as a whole is being flooded with large amounts of information. Mathematical Informatics gives effective theories and methods for extracting and analyzing meaningful information, analyzing it and making decisions based on it.

In this major, we will build mathematical models to understand real world phenomena in nature and society, from the viewpoint of data analysis and informatics. By utilizing logical thinking and imagination to understand and develop mathematical models, which is fundamental to modeling, students will be able to develop a deeper understanding and interpretation of the phenomena through the use of informatics.

And through this, mathematical scientific methods are acquired for researchers and highly-skilled information engineers who play a core role in the application and development of informatics.
