Microbiology and Immunology


Microbiology is the study of microorganisms like bacteria, fungi, viruses, protozoa and parasites. Microorganisms play an important role in the environment and in human, animal and plant life and disease. Immunology studies our immune system's structure and processes. If you’re interested in microbiology and how the body fights infection and disease, the BSc. Microbiology and Immunology Major might be the right program for you. 

The curriculum provides a substantial background in microbiology, immunology and related disciplines (chemistry, biology, biochemistry), which will prepare you for professional schools, graduate education, or entry into jobs in industry or research institutes.


As a graduate from the Microbiology and Immunology Major, you can pursue careers in scientific research or acquire job positions in health, research, clinical, and medical institutes. You may also wish to pursue graduate studies in the field. 

You could become a professional: 

  • Forensic laboratory technician
  • Laboratory assistant
  • Pharmaceutical sales representative
  • Food technologist
  • Medical technologist
  • Biological researcher
