Computer Science Electives

At least 24 units of computer science electives, selected from any CSE courses with an S, M, T or A suffix. In satisfying these technical electives, up to 6 units may be taken outside the CSE classroom. Independent work (CSE 400E, CSE 497-CSE499) is possible by finding a suitable faculty mentor for the work. Such work can be classified as S, M, T or A with approval. Some or all of the 6 units may also be satisfied by taking courses in other departments, including those outside of the Engineering School. Students can seek approval for courses by contacting the associate chair.

Math Requirement

Calculus (Math 131) and Probability (ESE 326 or Math 3200, or the sequence DAT 120 & DAT 121).

Second Major in Computer Science + Mathematics

The McKelvey School of Engineering and the College of Arts & Sciences have developed a new second major that efficiently captures the intersection of the complementary studies of computer science and math.

Data Science Technical Electives

Four courses from Mathematics & Statistics or Computer Science & Engineering can be chosen from an approved list (below), with the following caveats:

  • At least one course from Mathematics & Statistics (at the 400 level or above)
  • At least one course from CSE (ending in S, T, M, or A)
  • At most one course on the 200 level
Ethics and Professional Responsibility Requirement (EPR)
  • Three units of courses from an approved list (Below)
Practicum Requirement
  • 3 units of an approved comprehensive data science project or experience. A practicum must be approved by the committee of data science faculty.
  • The practicum experience should be completed the next-to-last semester of study (i.e., first semester senior year). It is important that practicum plans be submitted for review prior to starting the project or course work to ensure the proposed work is sufficient for the objectives of the practicum. After the fact approvals are possible but not guaranteed.
  • Appropriate practicum work is possible via Independent Study (CSE 400E or Math 400), or via project-focused classes, including (but not limited to) CSE 437S Software Engineering Workshop and CSE 454A Software Engineering for External Client. Students should contact course instructors in advance to identify the degree of agency the student will have over project selection and requirements. 
  • Contact Maria Sanchez (smaria@wustl.edu) in the CSE department office or the Math department office to initiate the approval process.
