Computer Science has evolved into a distinct discipline characterized by three basic paradigms (theory, abstraction and design) with fundamental roots in both Mathematics and Engineering. Computer Science is the systematic study of algorithmic processes - their theory, analysis, design, efficiency, implementation and application - that describe and transform information 1 . The principle mission of the Trinity University Computer Science Department is to provide a state of the art foundation of principles, skills, knowledge and creativity for the development of liberally educated computer scientists of the highest quality. Students in the Department are among the most highly motivated, intelligent and talented Trinity students. The Computer Science program is designed to provied an appropriate mix of current technology and theory and also challenges its majors to think critically and communicate effectively. A student's experience in this discipline would include a substantial interaction with computers, but would also include broad training in the areas of systems, applications and theory of computing. At Trinity, computer science is not limited to programming, but also involves a much broader view of the discipline. The underlying theory of computer science and its range of applications are of equal importance, and this perspective allows for the breadth and depth of study that is essential to keep pace with the rapidly changing and growing field.

Trinity University is rated as one of the finest liberal arts and sciences universities in the country. Not only does Trinity University have an outstanding computer science major, it has excellent companion programs in the Division of Science, Mathematics and Engineering. Our computer science majors often complete optional minors in one of the fields of mathematics, physics, biology, geoscience, engineering, business, economics, communications or accounting.

A recently revised curriculum has been designed following specific guidelines set down by the Association for Computing Machinery (ACM). A major in computer science requires the completion of 42 semester hours of computer science and related disciplines. Courses include programming languages, computer architecture, data structures, computer graphics, software engineering and many others.

The Computer Science Department has been continually developing and revising its curriculum. We are convinced that its present form provides the proper balance between theory and application through a collection of core principles courses. The computer science major also includes a sequence of three seminar courses, taken in the Spring semester of the sophomore, junior and senior years, which emphasize the design process, professional conduct and ethics.

In the Spring of 1970, the University Curriculum Council established a separate Department of Computer Science. Dr. John E. Howland was hired to chair the Department and develop an undergraduate major in Computer Science, as well as to recruit a Computer Science faculty.

Prior to 1970, two computer science courses were being taught: a numerical analysis course in the Mathematics Department and a programming course in the Engineering Science Department.

During the 1970-1971 academic year, a Computer Science curriculum was developed following ACM guidelines (the ACM is the primary professional organization for Computer Science). Several students who were majoring in either Mathematics, Physics or Engineering Science were among the first Computer Science graduates in 1972. This graduation established Trinity University as the first college or University in the Southwest to graduate students with a major in computer science. During the years 1972 through 1975, the number of graduates with majors in Computer Science were 4, 8, 4 and 13. During the years 1976 to the mid 1980's, the number of majors in Computer Science gradually grew from about 20 to more than 150.

In the 1971-1972 academic year, the Computer Science faculty increased to three plus several part-time instructors. During the 1972-1973 year, a fourth faculty member was added to the Department and the faculty remained that size until the 1976-1977 academic year when the Department's first woman faculty member and another new Ph.D. were hired.

During the 1973-1974 academic year, the University Graduate Council approved a Master's degree program in Computer Science. This program continued until the 1987-1988 academic year when, at the recommendation of the University, the Department voted to discontinue its graduate program so that it could devote all its resources towards improving the quality of its undergraduate offerings. This decision was part of a broader University initiative to terminate Master's level programs in all but a few professional programs. During the mid 1980's, when the graduate program was at its peak, each year 60 to 80 graduate students were in varying stages of completion of their Master's degrees.

During the 1981-1982 year, two faculty were added, bringing the Computer Science Department to a total of eight faculty. During the mid-1980's, the faculty grew to a maximum of ten full-time professors, each holding the Ph.D. degree in computer science or a closely related field.

In the early 1990's, the Department was down-sized to seven Ph.D. faculty members due to the discontinuation of the graduate program. The 2000 - 2001 academic year finds the department with eight full-time and three part-time faculty. The Computer Science Department has grown to about 145 majors, making it the second largest department on the campus.

Often colleges and universities use graduate assistants to teach undergraduate courses. Trinity does not use graduate students to teach any of its classes! All computer science classes are taught by full-time faculty who have doctorates in computer science or a closely related area.

The average class size for freshmen level classes ranges from 15 to 30. The average class size for sophomore, junior and senior level classes ranges from 10 to 25. Smaller classes mean that students have an opportunity to work closely with faculty who are dedicated teachers and researchers.

We feel that it is important to be exposed to a variety of hardware systems. All students have the opportunity to use Unix and Windows systems. Many of our laboratory systems have multiple boot software systems so that they may be used as MacOS or Windows systems. Recently, the Linux operating system has been deployed in some of our laboratories allowing the same Unix based software to run on Macintosh and Intel machines as runs on our Silicon Graphics Unix machines. Since Linux, which is distributed under the GNU software license, is free, students can install Linux on their own computers and run the same software systems which the Department uses in its teaching and research.

The Computer Science Department provides 107 computers for student, faculty and staff use. Thanks to grants from the Semmes Foundation, Meadows Foundation and the National Science Foundation, the Computer Science Department maintains three laboratories for student use. The Unix Laboratory (Halsell 228) contains 22 Pentium III Linux workstations which can also run the Windows 2000 operating system. This laboratory is a combined lecture room and laboratory room which operates on a 24-hour per day basis. Since each Unix workstation supports multiple users, the machines in this lab may be accessed by students in other labs or residence halls even while the room is in use as a lecture room. Each machine in the Unix lab is connected to a Cisco 4006 series switch by a dedicated 100MB ethernet cable. The switch allows these 22 machines to participate in the Department's 66 procesor Beowulf parallel processing system.

The Department provides a common password database (NIS) and home directory server (NFS and SMB) for use on all of the Unix and NT machines. Students can develop, for example, OpenGL graphics programs on a Linux machine and then log into a Silicon Graphics workstation and re-compile the program to run at higher levels of performance.

Students may access all University computing services, including e-mail, Internet and World Wide Web from each of the Department's laboratories, as well as student owned machines in residence halls.

Another laboratory is the Graphics/Parallel Processing Laboratory (Halsell 200). This lab contains five high performance Silicon Graphics workstations and a BeBox dual PowerPC processor machine. This laboratory also houses seven dual Pentium III processor machines, each having 1G memory and 18.2G disk, which run the Linux operating system and form a principle computational resource of the Department's 66 processor Beowulf parallel processing system. The Beowulf system also has server machine which has 4 Pentium III processors, 4G memory and 72G of disk space. These machines are used primarily for graphics and parallel processing research projects.

A third laboratory, called the Workstation Laboratory (Halsell 342), is available. This lab contains 22 Intel Pentium III workstations which are configured to boot either Linux or Windows 2000 operating system. Each of these machines is connected to a Cisco 4006 series switch by a dedicated 100MB ethernet cable. The switch allows these 22 machines to participate in the Department's 66 processor Beowulf parallel processing system.

A fourth laboratory, called the Virtual Reality Laboratory (Halsell 330), contains three Silicon Graphics dual processor Windows NT graphics workstations which have large wide-format LCD displays. Also available in this lab are a variety of special peripherals such as head-mounted displays, 3-D glasses, 6-D joysticks, 3-D speakers and a data-glove. These machines are used for simulation and virtual reality research projects.

In addition, the Trinity University Computing Center provides about 1200 computers, approximately 400 of which are available to students. These machines are conveniently located in various campus laboratories such as the Library and Student Center. The Computing Center also maintains the campus internet and various server machines for e-mail, USENET and Web access. The Trinity internet is connected to the Internet by a one-third fraction of a Time Warner DS 3 line and is available in every campus building including residence halls. This network facility provides access to computing services in a convenient and consistent manner from all campus locations.

Trinity maintains about 1200 computers for students, faculty and staff use. About 400 of these machines are available for student use. The Computer Science Department maintains 107 computer systems for its students, faculty and staff. The following listing shows the details of these machines.

Computer labs in most buildings are open on a daily basis until 12:00 p.m. Most computer labs have doors with numeric keypad locks. After 5:00 p.m. lab doors are locked to provide security and access to students who know the lock access codes. Computer Science Department machines, being Unix based, are accessible 24 hours per day over the internet. This allows convenient access to machines and software from other locations, such as residence hall locations.

The campus internet provides Microsoft SMB networking services, TCP/IP and AppleTalk networking protocols. Higher level protocols such as WWW, FTP, e-mail, USENET, etc., are also available. The Trinity internet is connected to the Internet through a firewall so that all machines, including student owned machines located in residence halls, have the full range of Internet services, but are protected by the firewall from outside access. Students are able to buy, for a nominal fee, a network connection package which includes a network interface (if necessary) and network software drivers and utilities. Some limited dial-up access facilities are available to support students, faculty and staff who live off campus, however, most off campus use of Trinity's networks comes through commercial Internet Service Providers.

There are a variety of computing career opportunities for students who have learned a minimal amount of mathematics. Computer Science majors are required to take MATH 1311 (Calculus I) and at least two of the courses MATH 1312 (Calculus II), 1320 (Statistical Methods), 2324, PHIL 2340 (Symbolic Logic)

Several computer science students have received prestigious scholarships for undergraduate research. One of our students was awarded the Goldwater Scholarship, which amounted to approximately $7000.00 per semester. One of our Spring 1995 graduates received a National Science Foundation Fellowship to pursue a Ph.D. in computer science. This award was one of only 43 made to computer science students nationwide and covered all expenses at the University of Texas at Austin. Paradigm Simulation, Inc., Old Crows Foundation, USAA and Trident each have offered several scholarships for computer science students. The Department grants the Turing Award, Charles Babbage Award and SGI Award to the top graduating seniors in research and academic achievement, respectively. In addition, the Department maintains a file on scholarships and fellowships available to our students and always encourages students to seek these awards.

Recent graduates have been accepted directly into master's and doctoral programs at Princeton, Yale, Purdue, Ohio State, Penn State, University of California at Davis, University of Tennessee, University of Texas at Austin, Texas A&M, Duke, University of New Mexico, University of Wisconsin, Arizona State, Brown University, California Institute of Technology, Carnegie Mellon University, Harvard University, Indiana University, Michigan Institute of Technology, Notre Dame University, Pepperdine University, Rice University, Southern Methodist University, University of Colorado at Boulder, University of Houston, University of North Carolina at Chapel Hill, University of Oregon etc. Graduates have also entered law schools at Pepperdine, Harvard, Washington and Lee University and the University of Texas. Our graduates have received scholarships and fellowships from individual universities and the National Science Foundation. Recently, one of our graduates received one of only 42 National Science Foundation scholarships which covered all expenses for a Ph.D. degree at the school of her choice. The number of graduates attending graduate school varies from year to year. Recently, intensive job recruiting and high salaries have caused a decrease in the number of students entering graduate school. Also, some employers provide job benefits which pay for graduate school.

While in their undergraduate studies, students may secure part-time jobs, internships and summer employment with the many companies that call the Department seeking assistance. Many of these positions lead to full-time employment after graduation. About half of our graduates go on to work with larger companies such as Apple, IBM, Microsoft, Cisco, Texas Instruments, Ferranti International Control, Exxon, TRW, Fairchild Aircraft, Texaco, Motorola, General Dynamics, Tesoro Petroleum, Paradigm Simulation, Inc., EDS, USAA, UNISYS, EDP, DSC, Metier Management Systems, Southwestern Bell, Lockheed, USAF, Sandia National Laboratory, Apple, Dell, Compaq, Chrysler Corporation, Arthur Andersen, Southwest Research Institute, Origin Systems, etc. Because of the wide variety of opportunities for summer internships, undergraduate research and the extensive selection of elective courses, graduates accept jobs involving systems analysis, software design, software testing, computer graphics, database management, research and design as well as programming. Starting salaries for last year's graduates ranged from the high 40's to the mid 50's. Several graduates received signing bonuses as well.

The Department offers a program which leads to a Bachelor of Science degree with a major in computer science. A wealth of opportunity is open to a student who earns this degree. Because the discipline of computer science is experiencing explosive growth, it is estimated that the need for experienced professionals in this field will double by the year 2002. Several recent Trinity computer science graduates, who have chosen advanced studies, have been successful in gaining admissions to doctoral programs at the finest universities. Other recent graduates have entered highly sought industrial positions. Cisco, IBM, Exxon, EDP, Arthur Andersen, University of Texas Medical Center, Armstrong Laboratory and Southwest Research Institute are examples of companies who recruit undergraduate summer interns and co-op applicants. These positions often lead to permanent positions with the company.

The policy of the Department is to provide theory courses essential to graduate school, as well as applied courses essential in industry. Extensive advising sessions enable students to select courses which best compliment their occupational goals. Many doctoral programs prefer students which have the combination of theory course-work, as well as practical application courses. All students are encouraged to take the Graduate Record Exam (GRE).

More than one third of our undergraduate majors are actively involved in research with a faculty mentor. The Departmental computing laboratories support research projects in computer graphics, virtual reality, genetic algorithms, software engineering, functional programming, artificial intelligence, parallel processing, combinatorial mathematics and related fields. The Department recently completed a National Science Foundation Research Experience for Undergraduates program. This three year REU grant brought undergraduate students to the Trinity campus during the summer to work on virtual reality research projects. The Department encourages student researchers to publish research results by faculty co-authorship of papers and by student paper participation in the National Undergraduate Research Conference each year. During the last three years, student researchers have produced an average of 12 papers per year.

Some of our majors choose to complete a three semester Bachelor's thesis or an Honors thesis. Thesis options involve research and thesis writing as a substitute for completion of all or part of the senior software engineering project.

Many of our faculty have taught at large universities where class size is sometimes larger than 100 students. We are pleased that Trinity offers the opportunity to work with talented young people in much smaller classes. Student-faculty relationships are fostered by classroom interaction, office visitations, social gatherings, research collaborations, professional organizations, atheletic competition and programming competition.
