PhD in Department of Mathematics

The Department of Mathematics at Institute of Science Tokyo offers a PhD program in Tokyo, Japan. Teaching is in English, admission is available in April and October, and the doctoral course runs three years toward a PhD centered on original mathematical research and a dissertation. Research in the department spans pure mathematics areas such as algebra, analysis, geometry, and topology, alongside applied mathematics connected to modeling and computation. Doctoral candidates work under a faculty supervisor to develop an independent line of research, take part in departmental seminars, and are expected to present and publish results as part of the degree. Training in rigorous proof, mathematical reasoning, and problem-solving prepares graduates for careers in academic research, teaching, and quantitative roles in industry, including finance, technology, and applied research settings. 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. The dual April and October admission cycles give applicants flexibility in timing their entry into the doctoral program. English-medium teaching allows international applicants to pursue the PhD without Japanese proficiency, although required documents can differ depending on the intended academic supervisor, and some supervisors may request additional English test scores. Doctoral students in mathematics study within a graduate community at Institute of Science Tokyo that also includes physics, computing, and engineering departments, offering opportunities for interaction across closely related quantitative fields. Applicants are encouraged to contact a prospective supervisor before applying to confirm specific document requirements.
