The Master of Science in Interdisciplinary Mathematics (MSIM) at the University of Notre Dame's College of Science is offered to students who are enrolled in other PhD programs at Notre Dame. This program allows PhD students to supplement their primary research with advanced coursework and projects in mathematics, connecting mathematical concepts to real-world and interdisciplinary problems. The MSIM is not a general-admission master's program; applicants must already be pursuing a PhD at Notre Dame and have completed at least 30 credit hours with successful candidacy examinations. The program emphasizes the integration of mathematics with other disciplines, providing a valuable credential for those whose research is fundamentally mathematical in nature. 来源： https://graduateschool.nd.edu/degree-programs/interdisciplinary-mathematics-msim---masters-traditional/
