Computer Science At A Glance


Of students develop a software portfolio with contributions to the open-source community.

An emphasis on disciplinary breadth, as opposed to a narrow focus on programming

Concentrate on developing the ability to analyze ideas, to think logically, and to communicate ideas clearly and concisely. In this way, study of computer science contributes to the foundation of an excellent liberal arts education.

Integral hands-on laboratory component

Nearly all courses include a weekly laboratory session to provide for practice and experimentation using the scientific principles learned in the classroom, allowing for hands-on experience with a wide-variety of hardware and software systems.

Interrogation of human dimensions of computing

The human dimensions of computing — social, professional, and ethical implications — are treated throughout the department’s courses. Courses frequently feature collaborative and interdisciplinary in-class exercises and out-of-class assignments.

Become innovative and responsible experts in creating and developing technology.

Program graduates are well grounded in foundational knowledge and skills and several advanced and application areas. Students engage in the development of collaborative innovative software and interrogate ethical and responsible computing.

Students begin to gain understanding of the basic and practical foundations of computer science. Typically, one or two computer science courses from the introductory module are chosen in the first year. The introductory module emphasizes creative expression through the medium of a programming language, implementing, using, and evaluating the computational structures needed to efficiently store and retrieve digital data, and understanding the abstract structures used to represent discrete objects.

Computer Science Year 1

Students finish the introductory category and engage with the core courses, where they design, implement, evaluate, and document an algorithmic solution to a problem. Application courses in areas such as data analytics, data management, artificial intelligence, bioinformatics, robotics, and web development are available during this year. This is the year to participate in a research project, an internship, or employment as a departmental Technical Leader or Software Developer.

Computer Science Year 2

Students continue their core learning and explore their interests via application courses. They engage in Software Innovation courses, where technical and communication skills needed to design, implement, and publicly release innovative software are honed. Students also take a Junior Seminar course, where they learn to digest research in computing, state and motivate research questions, design and conduct experiments, and collect and organize evidence for evaluating scientific hypotheses.

Computer Science Year 3

Under the guidance of a faculty advisor, seniors design their project, conduct research, prepare a comprehensive document, and orally defend their work. Computer Science students complete significant projects that often result in the publication of conference and journal papers, the release of free and open-source software, and the creation of publicly available data sets. Students also take an advanced course in computer security, operating systems, or distributed systems.

Computer Science Year 4
