Computer Science at St. Mary’s

What is Computer Science?

Computer Science prepares graduates to write software and work with operating systems and architecture. It is a hands-on way to learn computing skills and will prepare you to understand algorithms, software architecture, design patterns, data structures and coding techniques.

The Computer Science program at St. Mary’s prepares students to manage a software development project through analysis, design, implementation, testing and maintenance. The program provides a deep understanding of the hardware and software components of computer systems and the following topics:

  • Data communication and databases
  • Hardware organization and operating systems
  • Software analysis and design methodologies
  • Software implementation and testing

Students learn from professors who have expertise in:

  • Artificial intelligence,
  • Game development and simulation,
  • Programming languages and
  • Computer security/Cybersecurity

Degree Plans

Students take 33 credit hours of courses, including a project. This program combines studies in the mathematical and theoretical foundations of computing with hands-on, practical scientific research. See the catalog for details:

Interested in saving time and money on two degrees? The Master’s in Computer Science can be combined two ways:

  • Earn both a Bachelor’s and a Master’s in Computer Science in as little as five years. An intensive course of study, undergraduate students can begin graduate course work during their senior year.
  • Earn both a Master’s in Computer Science and a Juris Doctorate law degree.


Students are expected to be able to write computer programs in a high-level programming language and to understand the connection between computer hardware and software before starting the degree program.

Two courses are taken from the Engineering Department. The Master of Science in Computer Science is sometimes offered off-campus at various locations, and some courses are offered in a hybrid or online format.

St Mary’s University offered me a challenging curriculum, which is relevant for the IT industry today. I also wanted a place where the professors genuinely cared about my success. Armed with the lessons learned while at St Mary’s, I went on to complete my Doctor of Computer Science.
