Undergraduate Major and Minor

The undergraduate program in computer science teaches the theoretical fundamentals 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.

Graduate Program in Computational Linguistics

The graduate program in computational linguistics is concerned with the scientific study of language from a computational perspective. It is an interdisciplinary field, which draws on linguistic theory (phonology, syntax, semantics, and pragmatics) and computer science (artificial intelligence, theory of computation, and programming methods).

Undergraduate Major and Minor

The Association for Computing Machinery (ACM) has developed a curriculum for computer science that is published annually. Much of the attached text is copied and reworded from the text for Computer Science Curriculum 2008.

Objectives

Computing is a broad field that extends well beyond the boundaries of computer science, drawing its foundations from a wide variety of disciplines. Computer science increasingly plays a methodological role in other disciplines and the impact of technology is a significant subject of study in fields like political science and journalism.

Majors in computer science learn to utilize concepts from many different fields, integrate theory and practice, and appreciate the value of good engineering design. They develop a high-level understanding of systems as a whole and an appreciation for the structure of computer systems, and the processes involved in their construction and analysis, that transcends the implementation details of the various components. They attain an understanding of the theoretical underpinnings of the discipline and how that theory influences practice. Many recurring themes such as abstraction, complexity, and evolutionary change are encountered during their course of study. Students are also educated as engineers, learning how to design, develop and maintain, large complex software systems and applications, integrating them into workplaces, and developing interfaces to them that support human use. Given the rapid continuous development of the field, majors are educated to be lifelong learners.

In recognition of the increasing significance of computer science as an important discipline for many students throughout the university, the department also offers a selection of courses relevant to students majoring in other disciplines or students double majoring in computer science and another concentration. Several courses enable students to develop skills and understanding of web technology and the impact of the Internet on society. Other courses provide students with the relevant skills and knowledge for assessing the adoption of new technology within an organization. Non-majors can learn the computing and modeling skills that support their work in their core discipline. Students in the social sciences can learn how the skills and methods from their core discipline are relevant for the development of user friendly technology, or the introduction of technology into the workplace.

Skills

Majors in computer science will develop a number of skills.

1. Understanding the elements of computational thinking.
2. Understanding the trade-off involved in design choices.
3. Identifying and analyzing criteria and specifications appropriate to specific problems, and planning strategies for their solution. Analyzing the extent to which a computer-based system meets the criteria defined for its current use and future development.
4. Deploying appropriate theory, practices, and tools for the specification, design, implementation, and maintenance as well as the evaluation of computer-based systems.
5. Specifying, designing, and implementing computer-based systems.
6. Evaluating systems in terms of general quality attributes and possible tradeoffs presented within the given problem.
7. Applying the principles of effective information management, information organization, and information-retrieval skills to information of various kinds, including text, images, sound, and video.
8. Awareness of security issues. Exposure to issues associated with access, encryption, and networking.
9. Applying the principles of human-computer interaction to the evaluation and construction of a wide range of materials including user interfaces, web pages, multimedia systems and mobile systems.
10. Learning to deploy effectively the tools used for the construction and documentation of software, with particular emphasis on understanding the whole process involved in using computers to solve practical problems.
11. Awareness of the existence of publicly available software (such as APIs or open source materials). Effective engagement in open-source projects. Exposure to effective software reuse.
12. Operating computing equipment and software systems effectively.

Additional skills prepare the majors for success as professionals:

1. Communication. Making succinct presentations to a range of audiences about technical problems and their solutions. This may involve face-to-face, written, or electronic communication.
2. Teamwork. Learning to work effectively as a member of a disciplinary or interdisciplinary development team.
3. Numeracy. Understanding and explaining the quantitative dimensions of a problem.
4. Self-management. Managing one's own learning and development, including time management and organizational skills
5. Professional development. Learning the skills necessary to continue one's own professional development after graduation.

Social Justice

The department does not currently offer a specific course to cover social and professional issues. However, many of these issues are distributed throughout the curriculum. Lifelong learning is a common theme of many of the elective courses. There are many opportunities for experiential learning and the development of oral communication and teamwork skills. Open software, freedom of information, patent and copyright law, software pirating, social inclusion and the digital divide, and the effect of the Internet on political discourse and free speech, are among the topics covered in the Internet & Society course.

Upon Graduating

The BS curriculum is intended for students who want to work as computer scientists in a technical firm or plan to attend graduate school in computer science. The BS requires more rigorous training in the analytic and engineering foundations of computer science. It includes a breadth component that exposes students to a range of topics within computer science, and it also includes a depth component that requires students to explore a sequence of courses in one area of computer science.

The BA requirement reduces the ACM curriculum to the basic set of skills and knowledge. Students graduating with the BA will be prepared to work as application programmers or in secondary areas related to computation like informatics or library science. The BA curriculum is also ideal for students who plan to use their degree in computer science as a basis for graduate study in a professional school or graduate programs in other areas of science or social science.

Honors

Graduation with honors in computer science requires completion and defense of a senior honors thesis. Students interested in senior thesis should contact prospective faculty mentors by the spring of their junior year and should take note of the prerequisites for enrollment in COSI 99d (Senior Research). To initiate Honors research, the students must have their Senior Thesis Application form signed by the faculty mentor, the Undergradute Advising Head; and submit the signed form to the Computer Science Office no later than the end of the spring semester of their junior year.

Available only to Brandeis students who have completed all requirements for the undergraduate Bachelors degree and have performed well in the computer science major and have completed three 100-level COSI electives in addition to those required for their undergraduate degree. Students should apply in their senior year, at which time they should propose a course of study for the fifth year that typically consists of six graduate-level courses of which at most three may be chosen from the following courses: COSI 152aj, COSI 152bj, COSI 153aj, COSI 153bj, COSI 154aj, COSI 293aj, COSI 210aj, COSI 200a,b and COSI 210a.

The five-year BA/MS or BS/MS degree program in Computational Linguistics is designed for outstanding undergraduate students who will have completed all requirements for the undergraduate BA or BS degree within four years at Brandeis, with a major in Linguistics and/or Computer Science. Eligibility for the program is normally limited to students who have maintained a minimum 3.500 GPA in all linguistics and computer science courses taken. Students complete the MS in Computational Linguistics by completing the first year courses for the two-year version of the MS in Computational Linguistics at any time during their undergraduate studies, and then completing the two-year degree’s second year courses in one additional (fifth) year of study. The MS degree provides a solid foundation for professional work in the field of computational linguistics or for additional graduate study in computational linguistics, computer science and/or theoretical linguistics. Interested students should consult with Computational Linguistics advising faculty as early as possible during their undergraduate studies, to make sure that all requirements can be planned for and completed on time. An application should be submitted by the Computational Linguistics MS degree’s regular application deadline during the student’s senior year.

Program of Study

Students admitted to the program must fulfill the following requirements, in addition to completing their undergraduate degree: a schedule of course work designed in conjunction with and approved by the director of graduate studies consisting of at least twelve courses. Among these twelve, all students are required to complete COSI 114a, COSI 114b, COSI 134a, COSI 137b, COSI 140b, and at least one of the computational linguistics internship course COSI 293b, the computational linguistics capstone project course COSI 295a, or the computational linguistics master's thesis course COSI 299a. The master’s thesis must be deposited electronically to ProQuest. Depending on student background, at the determination of the director of graduate studies, the remaining six courses may include required foundational courses in computer science and/or linguistics; electives; or a blend of the two.

Residence Requirement

The minimum residence requirement is one year after completing the BA or BS degree.

Students may submit a written request to count a course from another department to satisfy one of the required computer science electives. Approval of such a request is based on the relationship of this course to the student's other computer science electives.
