Computers have changed, and continue to change, what we do and how we do it in our homes, in our offices, and throughout our world. The discipline of computer science focuses upon the many challenging problems encountered in the development and use of computing systems and software. Areas of study in computer science range from theoretical analyses into the nature of computing and computing algorithms, to the development of powerful computing devices and networks, and from the design and implementation of sophisticated software systems, to the creation and use of machine learning systems that exhibit powerful artificial intelligence.
The department offers two undergraduate programs in core computer science: a Bachelor of Science (B.S.) in Computer Science and Bachelor of Science (B.S.) in Computer Information Systems; and a Bachelor of Science (B.S.) in Artificial Intelligence, and a Bachelor of Science (B.S.) in Data Science (in conjunction with the Applied Mathematics Department).
Both core computer science programs provide an excellent background in the field and allow for ample study in other areas. Where these programs differ is in the approach they take to computer science. The B.S. in Computer Science provides an in-depth experience focusing on the theory and practice of computer science while the B.S. in Computer Information Systems provides a more interdisciplinary experience, balancing study in computer science with study in another field. Both programs begin with a set of introductory courses that work together to provide students with a firm foundation in computer science. These introductory courses include regular labs wherein students analyze and solve a variety of problems using accepted software development techniques. Having completed the introductory core, a student is prepared to work independently within a well-structured design and coding paradigm in the classroom or on the job.
The last two years of study build upon this foundation. The B.S. in Computer Science focuses on the concepts and techniques used in the design and development of advanced software systems. Students in this program explore the conceptual underpinnings of computer science—its fundamental algorithms, programming languages, database systems, operating systems, and software engineering techniques. In addition, students choose from a rich set of electives including artificial intelligence, machine learning, biometrics, cloud computing, data mining, natural language processing, computer vision, computer graphics, information retrieval, information security, intelligent text analysis, knowledge management systems, and mobile application development, among others. As with the introductory sequence, these advanced courses stress “hands-on" learning by doing. Students can opt to complete one of the computer science specializations: data science, distributed and cloud computing, information security, or information and knowledge management systems. An allotment of free electives allows students to combine study in computer science with study in another field to complete a minor.
The B.S. in Computer Information Systems program emphasizes the use of computing for complex problem solving. Students in this program pursue an interdisciplinary course of study that combines a solid foundation in computer science with a focus in another discipline. This program is designed for students who seek to blend their computer science abilities with skills specific to another domain to solve problems in that domain. Examples include computing with a business focus (e.g., management information systems) or computing with a natural science focus (e.g., computational physics).
The B.S. in Artificial Intelligence (AI), one of the first degrees of its kind in the country, gives students the broad and deep foundations necessary to build computational systems that can interpret sensory input, learn from experience, understand human language, plan ahead, and support intelligent decision making. The program starts with introductory courses in programming, computer science, mathematics, and statistics that provide students with a firm technical foundation. Students are then prepared to learn core AI concepts and techniques including state-space search, game-playing, machine learning, neural networks, planning, computer vision, and language understanding. For breadth of understanding necessary in this interdisciplinary field, students choose from a diverse set of advanced courses in cognitive science, philosophy of mind, and linguistics, and also must complete a minor in another area. Given the societal impact of AI, emphasis is placed on ethics and social responsibility throughout the coursework. The program also includes a large variety of advanced AI electives to enable students to develop technical mastery in specific sub-fields.
The B.S. in Data Science gives students the analytical and computational skills needed to support decision making and operations in diverse industries. As such, this profession is in very high demand. In this multidisciplinary major students learn core computing, mathematics, and statistics concepts and techniques, and are trained in modern methodologies for data collection, organization, and analysis. Ethics and professional skills training are also integrated throughout the program, so graduates are prepared from day one to be successful data science professionals.
