Microbiology is the study of bacteria, viruses, fungi, the immune system, and their roles in human health, the environment and beyond. Job prospects for Microbiologists with a bachelor’s or higher degree continue to be strong. The upper-division major courses in immunology, pathogenic microbiology, virology and microbial genetics couple laboratory courses with lecture courses in order to provide students with hands-on practical experience with the material. The B.S. Microbiology major includes all four of the upper-division lecture and laboratory course pairs.
