Microbiology is a field of science that focuses on the study of microorganisms. Microbiologists are highly trained scientists that study the characteristics and growth of a variety of microscopic organisms and how they interact and affect plants, animals, human beings, and structures. Microbiologists need at least a bachelor degree in microbiology, but most positions require a master or doctorate degree. Most microbiology degree programs provide intensive classroom instruction and laboratory experience. Employment of microbiologists is expected to grow about as fast as average for all professions, increasing 11% from 2006 to 2016. The increase in awareness of preserving the environment and developing cures for diseases will drive job growth.
