Objectives
Undergraduate Major
The undergraduate program in computer science teaches the fundamentals of theoretical and practical aspects of computing, preparing students for creative jobs in the computer industry and/or for graduate school. In addition, our curriculum is a stimulating and useful preparation for a number of indirectly related professions, such as law, medicine, and economics.
Graduate Program in Computer Science
The Graduate Program in Computer Science is concerned with the fundamental concepts arising in the development and use of computing systems, including the study of computational complexity and information theory, the design and analysis of serial and parallel algorithms, the design of programming languages, systems, and artificial intelligence.
A normal program of study in computer science at Brandeis starts with two years of basic graduate course work. At the completion of this course work, students are eligible for a master's degree. During this initial two-year period, candidates for the degree of Doctor of Philosophy select a thesis topic and advisor. Dissertation research typically requires two to three additional years.
How to Become an Undergraduate Major
Previous experience in computer programming is helpful, but not necessary (students lacking such knowledge may take COSI 11a [Programming in Java and C] in their first year). As a rule, our course sequence should not be started later than the sophomore year.
How to Be Admitted to the Graduate Program
The general requirements for admission to the Graduate School, given in an earlier section of the Bulletin, apply here. Applicants for admission to the computer science program must submit three letters of recommendation and are encouraged to take the Graduate Record Examination, and the advanced test in computer science. Funds from research grants and fellowships are available to provide financial support for well-qualified students.

Teaching Requirement
The mentoring, training, and evaluation of teaching fellows is an ongoing and important component of the graduate program in computer science. Students normally teach one course per year, beginning as graders of problem sets and assignments and move progressively to higher levels of involvement with teaching in courses across the curriculum. They participate in the design and delivery of course lectures and each year, under the guidance of their faculty, they present several lectures. Whether students are preparing for an academic and research career, or an industry position, the teaching fellow experience is valuable training in course preparation and technical communication.
Thesis Committee and Proposal
1. Establishment by the advisor and the director of graduate studies of a thesis committee consisting of the advisor, two other Brandeis faculty, and one appropriate external member from outside Brandeis.

Thesis Defense
Public defense of a completed dissertation will be announced three weeks in advance. Copies of the complete thesis will be available to the faculty during these three weeks.
Residence Requirement
The minimum residency requirement is three years.
Language Requirement
There is no foreign language requirement.
