Graduate Program in Science and Technology/ Mathematics Division
We believe that the Mathematics Division not only provides a rich environment for studying and researching mathematics but what is more important is to actually conduct research activities of students’ own problems, solve them, and present their findings to the public. The joy of solving a problem after much thought is priceless, we hope this will be your experience during your time at Sophia University.
The career paths of graduates of the Master’s Program, including the former Graduate Program in Mathematics, used to be advancement to the Doctoral Program, teaching at junior high/high schools, finance, insurance, etc. However, in recent years, as society’s need for experts in mathematics have become greater, many graduates have been employed in companies in a wide range of industries. In addition to this, many graduates of Doctoral Program aim to work as researchers and many graduates have gained employments at universities, National Institute of Technology, and other institutions throughout Japan.
The Mathematics Division provides instruction with the “Mathematics Seminar” as the center of education and research. At the very beginning of the seminar, each graduate student reads and present a basic research paper or a technical book. However, once they decide their own research theme, they instead present the progress and results of their research. During this process, students also receive research guidance from their academic supervisors or faculty members, thus providing an important opportunity for students aiming to complete their thesis. In addition, students study specialized topics through lecture courses. This enables the students to link the basic mathematics learned in undergraduate courses with current cutting-edge research, making it possible for them to apply to their own studies.
- Master’s Program: Master of Science in Mathematics
- Doctoral Course: Doctor of Science in Mathematics
Available Teaching Licenses and Subjects
- Junior High School (Specialized; Mathematics, Science)
- High School (Specialized; Mathematics, Science, Industry, Informatics)
※Only Master’s Program students are eligible to obtain a teaching license. In addition, only subjects for a which a Type 1 license has already been obtained or for which the requirements for obtaining a Type 1 license have been met can be obtained.
Polite Research Guidance
The average number of graduate students per faculty member in the Mathematics Division is about one. Compared to national or public universities with larger number of students, the research guidance is more detailed and attentive to the level of each student.
Convenient Environment for Research
Apart from Sophia University Central Library, students have access to Sophia University Math. Library, where 35,000 specialized books and journals are available through the Online Public Access Catalog (OPAC) system. In addition, graduate students can borrow laptop computers.
Intercollegiate Auditors Program
The Graduate School Mathematics Liaison Council is comprised of 11 universities: Sophia University, Chuo University, Gakushuin University, International Christian University, Rikkyo University, Tokyo Women’s University, Tsuda University, Nihon University, Japan Women’s University, Meiji University, and Tokyo University of Science. Through this auditing student program, students can receive credits which could be counted as mandatory credits for graduation by attending the lectures at these universities.
