PhD in Department of Mathematical and Computing Science

The PhD program in the Department of Mathematical and Computing Science at Institute of Science Tokyo, in Tokyo, Japan, trains doctoral researchers across mathematics and computer science. Teaching is conducted in English, admission cycles begin in October, and the doctoral course runs three years toward a PhD centered on independent research and a dissertation. Study in this department covers pure and applied mathematics together with core computing topics such as algorithms, computational theory, data structures, and mathematical modeling. Doctoral candidates work with a faculty supervisor to define a research problem, present progress at seminars, and pursue publication in peer-reviewed venues as part of the degree. Graduates typically build strength in mathematical proof, algorithm design, statistical methods, and computational problem-solving, skills that carry into research careers in academia, software engineering, data science, and applied research at technology and finance firms. Institute of Science Tokyo was created in Tokyo through the October 2024 merger of Tokyo Institute of Technology, founded in 1881, and Tokyo Medical and Dental University, founded in 1928. The merged institution describes its mission as advancing science and human wellbeing to create value for and with society, combining specialized education with training in liberal arts and interdisciplinary skills. Because the program is delivered in English, it is accessible to applicants who are not proficient in Japanese, though additional test scores or documents may be requested by an individual supervisor depending on the intended research area. Students entering the department join a broader graduate community at Institute of Science Tokyo, where mathematics and computing sit alongside engineering, life science, and medical research, giving doctoral students in this department opportunities to engage with adjacent fields. Applicants are encouraged to identify a potential academic supervisor and confirm specific document and language requirements before submitting an application, since expectations differ by research group within the department.
