Mathematics-Computer Science

Students may opt to pursue an interdisciplinary Bachelor of Science degree in Math-Computer Science, a concentration administered cooperatively between the mathematics and computer science departments. Course requirements include math- and systems-oriented computer science courses, as well as computational courses in applied math. Students must identify a series of electives that cohere around a common theme. As with other concentrations offered by the Computer Science department, students have the option to pursue the professional track of the ScB program in Mathematics-Computer Science.

Requirements for the Standard Track of the Sc.B. degree.

Three semesters of Calculus to the level of MATH 0180, MATH 0200, or MATH 03503
MATH 0520Linear Algebra1
or MATH 0540 Honors Linear Algebra
Core Courses
MATH 1530Abstract Algebra1
Select one of the following series:2
Series A
Introduction to Object-Oriented Programming and Computer Science
and Introduction to Algorithms and Data Structures
Series B
Computer Science: An Integrated Introduction
and Computer Science: An Integrated Introduction
Series C
Accelerated Introduction to Computer Science
and an additional CS course not otherwise used to satisfy a concentration requirement; this course may be CSCI 0180, an intermediate-level CS course, or a 1000-level CS course
CSCI 0320Introduction to Software Engineering1
or CSCI 0330 Introduction to Computer Systems
CSCI 0220Introduction to Discrete Structures and Probability1
or CSCI 1010 Theory of Computation
Three 1000-level Mathematics courses3
Three advanced courses in Computer Science 13
Three additional courses different from any of the above chosen from Mathematics, Computer Science, Applied Mathematics, or related areas 23
A capstone course in Computer Science or Mathematics 31
Note: CSCI 1450 may be used either in place of CSCI 220 or 1010 in the core courses or as an advanced course. CSCI 1450 was formerly known as CSCI 450: they are the same course and hence only one may be taken for credit. Applied Math 1650 or 1655 may be used in place of CSCI 1450. However, concentration credit will be given for only one of Applied Math 1650, Applied Math 1655, and CSCI 1450.

These courses must be at the 1000-level or higher. The three courses must include a pair of courses with a coherent theme. A list of pre-approved pairs may be found at the approved-pairs web page. You are not restricted to the pairs on this list, but any pair not on the list must be approved by the director of undergraduate studies.


 These must be approved by a concentration advisor.


A one-semester course, normally taken in the student's last undergraduate year, in which the student (or group of students) use a significant portion of their undergraduate education, broadly interpreted, in studying some current topic in depth, to produce a culminating artifact such as a paper or software project.

Requirements for the Professional Track of the Sc.B. degree.

The requirements for the professional track include all those of the standard track, as well as the following:

Students must complete two two-to-four-month full-time professional experiences, doing work that is related to their concentration programs. Such work is normally done within an industrial organization, but may also be at a university under the supervision of a faculty member.

On completion of each professional experience, the student must write and upload to ASK a reflective essay about the experience addressing the following prompts, to be approved by the student's concentration advisor:

  • Which courses were put to use in your summer's work? Which topics, in particular, were important?
  • In retrospect, which courses should you have taken before embarking on your summer experience? What are the topics from these courses that would have helped you over the summer if you had been more familiar with them?
  • Are there topics you should have been familiar with in preparation for your summer experience, but are not taught at Brown? What are these topics?
  • What did you learn from the experience that probably could not have been picked up from course work?
  • Is the sort of work you did over the summer something you would like to continue doing once you graduate? Explain.
  • Would you recommend your summer experience to other Brown students? Explain.
