Bachelor of Science in Microbiology

Bachelor of Science Curriculum

Advising is mandatory; see a departmental advisor as soon as possible.

Student learning outcomes

Upon graduation, Microbiology majors should have a thorough knowledge and comprehension of the core concepts in the disciplines of molecular, cellular and organismal microbiology. In addition students will exhibit proficiency in selected laboratory skills and develop knowledge of contemporary microbiological research. This background of knowledge and experience will prepare the students for entry into professional/graduate school or for employment in government, academic or industrial positions.

Specific learning outcomes include knowledge and understanding of:

  • The physiology, biochemistry and genetics of bacteria including cell structure, function, diversity, metabolism and the genetics of metabolic regulation.
  • The immune response and disease-causing microorganisms including aspects of the humoral, cell-mediated and non-specific immune responses, as well as molecular bases for pathogenesis.
  • Taxonomic, ecological and genetic relationships among microorganisms including nutrient cycling, microbial diversity and the biotechnological application of microorganisms to solve environmental problems.
  • The scientific method of investigation and hypothesis testing including the development of theoretical and practical skills in the design and execution of experiments.

Note: You should take BIOL 171-171L (3+1), Introductory Biology (prerequisite to BIOL 172-172L), as a Natural Science course counting towards your core requirements.

  • Major electives should be chosen with the aid and approval of the department advisor to provide a well integrated and coherent program.
  • Attention is called to the College of Arts and Sciences Basic requirements and to those in areas of language and culture, humanities and social sciences. It is the student’s responsibility to meet these requirements.
  • Prerequisites, micro requirements, required related courses and major electives cannot be taken CR/NC; they must be taken for a letter grade.
  • Students can do a laboratory teaching internship and obtain a course credit for MICR 499. Students should have previously taken a laboratory class and obtain permission from the instructor.

Sample Schedule

  • Freshman Year: Start the chemistry and mathematics sequences as early as possible. Take Biology 171 and 172 if possible.
  • Sophomore Year: Take Chem 272/272L, 273/273L, Physics; Micr 351, 2nd semester as soon as Chem 272 is taken.
  • Junior Year: Take Micr 351 1st semester, if not yet complete. Biochemistry and other major electives may also be taken. Biochemistry is desirable for students who wish to take Micr 461, 431, 490.
  • Check early on Arts and Science requirements to avoid conflicts and problems in the senior year, e.g., language and/or required “core” courses.
