After completion of introductory microbiology and other core courses, students pursuing a Bachelor of Science in Microbiology study the structure, growth and metabolism, physiology, and genetics of viruses, bacteria, fungi, and the diseases that they produce. Students also study how the vertebrate immune system works to combat those diseases. Micro majors take courses that explore how cells receive signals from their environments, how cells adjust to read different sets of genes, and how cells can be genetically engineered. Other topics of study include public health, tumor biology, yeast cell biology, and molecular biology. This option prepares students for a variety of careers, including business, law, biotechnology, medicine, public health, or research.
