Guide to Microbiology Careers

Microbiologists study a world invisible to the naked eye, a world of living microorganisms. Through an intersectional approach that incorporates mathematics, physics, chemistry, and genetics, microbiology is changing the world at the microscopic level. The applications of microbiology affect the water we drink, the food we eat, the medicine we take, and the consumer products we use every day.

The Bureau of Labor Statistics projects jobs for microbiologists to increase 8 percent between 2016 and 2026, about as fast as the national average. But that only paints a small part of the picture: the study of microbiology can lead to a plethora of diverse career paths, ranging from the environmental, to the clinical, to the industrial.

And microbiology has grown by leaps and bounds since the revolutionary discoveries of Louis Pasteur and Robert Koch. Merged with advances in modern technology, microbiology is now one of the fastest moving disciplines in the life sciences, fueling new developments in drugs, vaccines, and industrial enzyme research.
