Computer Science, Mathematics and Science

    Computer Science is a fast moving and ever-changing discipline. St. John's University’s programs in computer science and related areas are built around a core of key courses structured to provide a solid foundation of knowledge leading to careers in technology. These courses bring together the theory and practice of computing to provide students with knowledge and skills to solve a wide range of technical and business problems.

    Degree Programs

    There are five major degree programs of study offered by the Division of Computer Science, Mathematics and Science which address the mainstream needs of careers in the broad fields of Computer Science, Cyber Security Systems, Healthcare Informatics, Information Technology, and Telecommunications.  Each of these majors can be paired with a choice from several options, providing the students with the ability to concentrate on important and relevant areas that help prepare them for positions that meet their interests and aptitudes. One very popular minor option is in business, which provides many background courses needed for admission to a master of business administration degree program.

    The following degree programs have been accredited by the Computing Accreditation Commission of ABET,
    Computer Science, BS
    Cyber Security Systems, BS
    Information Technology, BS


    The faculty are dedicated to providing a quality educational experience in these fields. They are constantly re-assessing course offerings to keep the program relevant and competitive to the rapidly changing world of technology. Many industry professionals teach part time, bringing their real life expertise into the classroom.
