The

Department of Computer Science offers programs leading to the degrees of bachelor of arts and bachelor of science in computer science, and the M.S. and Ph.D. in computer science. The B.A. is a College of Letters and Science major; the B.S. is a College of Engineering major. Both the B.A. and B.S. degree programs in computer science are accredited by the Computer Science Accreditation Commission of the Computing Sciences Accreditation Board.

One of the most important aspects of the Computer Science program at UCSB is the wealth of "hands-on" opportunities for students. UCSB has excellent computer facilities. Campus Instructional Computing makes accounts available to all students. Their facilities include late model PCs and MACs as well as NeXT workstations. Computer Science majors use the UNIX workstations in the Computer Science Instructional Lab and Engineering Computing Infrastructure computing facilities. Students doing special projects can gain access to machines at the NSF Supercomputing Centers via the Internet.

Graduate students have the additional computing facilities available in the Graduate Student Laboratory. Students working with faculty have access to the specialized research facilities within the Department of Computer Science: the Reliable Software, Theory of Computation, Distributed Systems, Parallel Systems, and Vision Laboratories.

The undergraduate major in computer science has a dual purpose: to prepare students for advanced studies and research and to provide training for a variety of careers in business, industry, and government.

Undergraduate counseling is provided under the direction of the assistant to the dean for undergraduate studies. A faculty advisor is also available to help with academic program planning. A department publication, Undergraduate Studies in Computer Science, describes degree offerings, new courses, and requirement changes.

Computer Engineering Major

This major is offered jointly by the Department of Computer Science and the Department of Electrical and Computer Engineering. For information about this major, refer to the section on Computer Engineering.

Mission Statement

The Computer Science programs seek to prepare undergraduate and graduate students for productive careers in industry, academia, and government, by providing an outstanding environment for teaching and research in the core and emerging areas of the discipline. The programs place high priority on establishing and maintaining innovative research programs that enhance educational opportunities and encourage a broad base of extramural support.

Program Goals for Undergraduate Programs

To prepare computer professionals for long-term careers in research, technical development, and applications. Baccalaureate graduates, ready for immediate employment, are eminently trainable for most Computer Science positions in government and in a wide range of industries. Outstanding graduates interested in highly technical careers, research, and/or academia, should be fully prepared to further their education in graduate school.

The primary computer science emphasis is on computer program design, analysis and implementation, with both a strong theoretical foundation and a strong practical component, covering most aspects of computing and computer communications.

BS and BA computer science degrees are equivalent with a difference in emphasis. The BA program requires more general education courses, and the BS program requires additional computer science courses.

Educational Objectives for the Undergraduate Programs

On completion of the programs, undergraduates should be able to:

In addition, undergraduates must:

Admission to the Major

The pre-major requirements for the B.A. and the B.S. degrees in computer science are the same. Students intending to major in computer science should declare a pre-major when applying for admission to the university. It is strongly recommended that incoming freshmen complete a programming class prior to enrollment at UCSB. We recommend a Java course with emphasis in programming or a C++ programming course. Students who declare a pre-major are responsible for satisfying degree requirements in effect at the time of their declaration. When students have completed the preparation courses, they must petition to declare a change from pre-major to major status.

Students applying for major status in the BS program who have completed more than 105 units will NOT be considered for a change of major/change of college unless they can demonstrate that they will be able to complete all of the degree requirements for the proposed program without exceeding 195 total units. (Exceptions may be granted to students who have enrolled in more than the normal number of units per quarter).

Students applying for major status in the BA program will NOT be considered for a change of major/change of college unless they can demonstrate that they will be able to complete all of the degree requirements for the proposed program without exceeding 200 units or no more than 5 total years of post-secondary study, including time enrolled at other institutions.

Students may petition to enter the computer science premajor at any time Option A below has been met, or they may petition to enter the full major when Option B has been met.

Option A: Satisfactory completion at UCSB of at least four 4-unit courses required for the computer science preparation for the major, including at least two computer science courses, with a University of California grade point average of at least 3.0 in all the preparation for the major courses taken.

Option B: Satisfactory completion of all the preparation for the major requirements with a University of California grade point average of at least 2.75.

Transfer Students: students who transferred to UCSB to a major or premajor other than computer science will find it very difficult, if not impossible, to change their major to computer science.

Please Note: Pre-major status does not guarantee admission to major status. All courses required for the preparation must be taken for a letter grade. To be admitted to the major, the student must complete the preparation with a minimum grade point average of 2.75. No exceptions will be made to the GPA rule.


Undergraduate Program

Courses required for the pre-major or major, lower- or upper-division, inside or outside of the Department of Computer Science, cannot be taken for the passed/not passed grading option. They must be taken for letter grades.

Preparation for the majorB.S. and B.A.

Required: Mathematics 3A-B-C and 5A-B; Computer Science 10, 20, 30, 40, 50, and 60; and Probability and Statistics 120A. Courses identified as options within the preparation are considered equivalent; students may take one of them to satisfy the requirement but may not take more of them for credit.

Bachelor of Science--Computer Science

Upper-division major

The following courses are required: Computer Science 110A or 110B, 130A-B, 136, 154, 160, 162, 170, 186; Electrical and Computer Engineering 152A; and Probability and Statistics 120B. In addition, at least 16 units of major field electives are required. Prior approval of these electives must be obtained from the faculty advisor. In addition, the following courses are required: Engineering 101, Physics 1, 2, 3, 3L and at least 8 units of science, mathematics, and engineering electives. Lists of approved science, mathematics, and engineering electives are available in the computer science office.  

Bachelor of Arts -- Computer Science

Upper-division major

The courses required for the B.A. are the same as for the B.S. degree, with the following exceptions: Computer Science 160 is not required; 7, rather than 16, units of major field electives are required; a science sequence and two additional science courses are required. The science sequence should be selected from: Chemistry 1A-B-C and labs, or Physics 1, 2, 3, 3L or Physics 6A-B-C and labs. A list of approved additional science courses is available in the Computer Science office. In addition, students are required to take Engineering 101 or Philosophy 4, 6, or 100A.

Five-Year Bachelor of Science/Master of Science Program

A combined B.S./M.S. program in computer science provides an opportunity for outstanding undergraduates to earn both degrees in five years. Additional information about this program is available from the undergraduate office or from the computer science graduate program assistant. Interested students should make their interest known to the department early in their junior year. In addition to fulfilling undergraduate degree requirements, B.S./M.S. degree candidates must meet Graduate Division degree requirements, including university requirements for academic residence and units of coursework as described in the section "Graduate Education at UCSB."


Graduate Program

In addition to departmental requirements, program applicants and candidates for graduate degrees must fulfill University requirements described in the section "Graduate Education at UCSB."

Admission

In addition to fulfilling the Graduate Division requirements for admission found in the chapter "Graduate Education at UCSB," the Department of Computer Science requires a bachelor's degree in some discipline of science, engineering, or mathematics.

Applicants must have a grade-point average of at least 3.0 in their last two years of undergraduate study. Satisfactory performance in the verbal, quantitative, analytical sections of the Graduate Record Examination is required of all applicants. Applicants whose native language is not English are required to take the Test of English as a Foreign Language (TOEFL). Exceptions to this requirement will be considered for those students who have completed an undergraduate or graduate education at an institution whose primary language of instruction is English. The minimum score for consideration is 600 on the paper-based test and 250 on the computer-based test. Applicants who have received a bachelor's or master's degree from a U.S. college or university are exempt from this requirement.

The Test of Spoken English is required for international students applying for teaching assistant positions.

All fall application materials must be received by April 1. If an applicant wishes to be considered for fellowships and assistantships, all application materials must be received by January 1.

Master of Science Program--Computer Science

Degree Requirements

The purpose of the Master of Science program is to provide advanced training in computer science to prepare students for positions in industry and government and for further graduate study. The program is designed to accommodate students with training in diverse scientific and engineering disciplines, and in this regard the graduate program relies on the undergraduate program to provide the necessary course work for graduate students with deficiencies in their computer science backgrounds.

There are three tracks for the Master of Science program: with a thesis, with a comprehensive examination, or with a project.

Requirements Common to All Tracks

There are three major areas Theory, Systems, and Applications. Every graduate course in the department is classified into at most two major areas. The following requirements are common to both tracks.

Additional Requirements for Plan I: Thesis

The student must submit an acceptable thesis, completed under the supervision of a Computer Science permanent faculty member, and approved by a thesis committee composed of 3 permanent faculty members of the Computer Science Department. At most 12 units of 596 and 598 can be used towards unit requirements.

Additional Requirements for Plan II:
Comprehensive Examination

Besides the six courses required for all plans, twelve additional units of coursework must be completed with 100 (excluding 190+) and 200 level courses. Of these, eight units must be at the 200 level. Plan II is available only to students who initially joined the graduate program as master of science candidates.

The comprehensive examination will be offered twice a year, in the eighth week of the fall and spring quarters. Each student will list four courses; a question from each of these courses will be asked on the examination. Three questions need to be answered.

Comprehensive Examination Project Option

As an option under Plan II, the project plan requires more coursework than the thesis plan but less research, establishing a useful intermediate position between the other two plans. Beyond the major area and breadth courses common to all plans, the project plan's course requirements are identical to those of the comprehensive examination plan. In addition to these course requirements, the student must complete:

This plan is available only to students who initially joined the graduate program as master of science candidates.

Study Plan

Upon entry into the graduate program, each student is assigned a faculty advisor who guides the student through his/her graduate career. In consultation with his/her faculty advisor, each student prepares a Study Plan, which details the courses that will be taken in order to fulfill the course requirements. The study plan may be changed at any time with the approval of one's faculty advisor and the graduate advisor. While the rules of the Graduate Division describe the conditions under which a student may withdraw from a course, the Department imposes the additional condition that if a student withdraws from a course that affects the study plan, then a new study plan must be prepared prior to withdrawal.

Doctor of Philosophy -- Computer Science

Admission

Students may apply directly to the Ph.D. program without a master's degree. However, a solid background in computer science or one or more fields of science and engineering is expected. Applicants to the Ph.D. program must have a grade-point average of at least 3.5 in their last two years of study. Students entering this program should be committed to completing a Ph.D. The department discourages students petitioning to switch to the master's program; such petitions are approved only under exceptional circumstances.

Objective

The purpose of the Doctor of Philosophy program in computer science is to prepare students for research and teaching positions in universities and colleges, and for research and leadership positions in industry and government. The primary aim of the program is to train students in the methods of scientific inquiry and independent research. This is accomplished through advanced coursework and active participation with the faculty in their research programs. Doctor of Philosophy students are expected to have a broad knowledge of all fields of computer science and have a deep understanding of at least one of its areas. In addition to this requirement, a Doctor of Philosophy student must be up to date in all the developments in his/her major area of specialization. The most important component of the Doctor of Philosophy program is learning to perform independent and significant research in one's area of specialization.

Requirements for the Doctor of Philosophy degree typically are completed in four to five years, depending on whether or not a student enters the program with an M.S. in computer science.

Course Requirements

To ensure sufficient breadth at the graduate level, Ph.D. students must complete at least eight graduate courses with a grade of B or better. Students are expected to be well-rounded in the following subject areas: foundations of computer science, systems, and applications. The set of courses that students plan to take must be endorsed by the academic advisor and another Department of Computer Science faculty member. A graduate level course taken in another department or another university can be counted if endorsed by the academic advisor and another faculty member.

Exam Requirements

To earn a Ph.D., students must successfully complete four examinations: the screening examination; the oral major area examination (qualifying examination); the thesis proposal; and the dissertation defense.

The screening exam, which consists of ten subject areas, is to ensure the student's breadth of knowledge at the undergraduate level. A subject area can be passed with either a passing grade in the screening examination or with a grade of A- or better in the course taught at UCSB. Although students are not required to pass all the subject exams at the same time, students are strongly encouraged to successfully complete all the subject areas as early in their graduate careers as possible. A student must satisfy this requirement within the first six quarters of residence in the Ph.D. program. Students on financial support should pass the exam within the first year in order to be considered for second-year support. The exam is offered twice a year: once during the fall quarter and once during the spring quarter. Although the exam material is chosen from the upper-division undergraduate curriculum, students must show a level of skill and a perspective appropriate for graduate work.

After passing the screening examination, a student forms a doctoral committee to supervise dissertation research. The doctoral committee must be chaired by a ladder faculty member from the department, although faculty from other UCSB departments may also be members. In special circumstances, non-UCSB faculty may be members. After the doctoral committee approves a student's proposed major area, the major area examination tests the student's knowledge of this area and any supporting areas (e.g., mathematics and electrical engineering). As a part of this examination, a student submits a set of relevant papers from the major area and prepares a brief presentation. Passing this oral examination allows this student to advance to candidacy for the doctoral degree.

After passing the major area examination, a student prepares a dissertation proposal that describes the dissertation topic, summarizes the relevant background literature, and presents a comprehensive research plan for the doctoral dissertation. The thesis proposal examination, which is oral, determines the feasibility of the research plan and the appropriateness of the research topic. The examination is administered by the student's doctoral committee.

The final examination is the defense of the candidate's dissertation, which consists of a public seminar and an evaluation by the candidate's doctoral committee on whether the student has successfully defended the dissertation.

Optional Graduate Degree Emphasis in Computational Science and Engineering

The Departments of Chemical Engineering, Computer Science, Electrical and Computer Engineering, Mathematics, and Mechanical and Environmental Engineering offer an interdisciplinary master's and Ph.D. degree emphasis in computational science and engineering (CSE).

CSE is a rapidly growing multidisciplinary area with connections to the sciences, engineering, mathematics, and computer science. Computer models and simulations have become an important part of the research repertoire, supplementing (and in some cases replacing) experimentation. Going from application area to computational results requires domain expertise, mathematical modeling, numerical analysis, algorithm development, software implementation, program execution, analysis, validation, and visualization of results. CSE addresses these issues.

Although CSE includes elements from computer science, applied mathematics, engineering and science, it focuses on the integration of knowledge and methodologies from all of these disciplines and, as such, is a subject distinct from any of them.

All students pursuing an emphasis in CSE must complete the following:

CSE master's and Ph.D. graduates are expected to have a solid grounding in CSE core subjects discussed above. A CSE thesis or dissertation should involve the solution of a real-world problem, using and/or developing tools to advance the CSE discipline. Some examples of such problems include, but are not limited to: data mining, computational chemistry, parallel computing tools for scientific computation, computational fluid dynamics, computational engineering and materials, and problem solving environments.

The specific requirements for the M.S. in Computer Science (thesis option only) with the CSE emphasis are as follows:

The thesis must be written under the supervision of a Computer Science CSE ladder faculty member. The thesis committee must include a minimum of three permanent ladder faculty members, at least two from Computer Science and one from CSE (may be CSE faculty member from another department).

Students pursuing a Ph.D. with an emphasis in CSE must:

The student's dissertation must be written under the supervision of a Computer Science CSE ladder faculty member. The doctoral examination committee must include at least one CSE ladder faculty member and at least one ladder faculty member from another department.
