Guide to Microbiology Careers
Search For Schools
Microbiologists study a world of living microorganisms invisible to the naked eye. Microbiology is changing the world at the microscopic level through an intersectional approach that incorporates mathematics, physics, chemistry, and genetics. 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 (2022) projects jobs for microbiologists to increase 9 percent between 2021 and 2031, on par with 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.
The ten careers profiled below meet the following criteria:
- They all have active job listings across the United States
- They include a balanced mix of educational entry points (associate’s degree, bachelor’s degree, master’s degree, and PhD)
- They offer an earnings potential above the national mean of $58,260 per year (note that microbiology research associate falls just below this figure, on a median scale, due to a lack of specified salary data)
- They are supported by the American Society of Microbiology (note genetic counselors, due to their status as an emerging field, do not yet meet this criterion)
Become an Agricultural and Food Scientist
Agricultural and food scientists use microbiology to study the deterioration of food, soil degradation, the causation of plant and animal diseases, and possible methods of increasing soil fertility. They may inspect agricultural or food production sites for compliance with safety and sanitary regulations, develop food and crop processing policies that maximize safe outputs, and study methods for preference optimization in harvests and food products.
Jobs and Pay
The BLS (2022) projects that the need for agricultural and food scientists will grow 8 percent between 2021 and 2031, adding over 3,000 jobs. Salary data suggests that the 13,510 agricultural and food scientists make an average of $84,150 annually. The percentiles are as follow:

The WASC Senior College and University Commission accredit the school.
Become a Biosafety Specialist or Officer
Biosafety specialists inspect laboratories and other facilities to ensure the area and practices within that area follow all safety regulations. Those with a microbiology background are best equipped to determine what poses an unseen hazard in a specific setting.
In addition to inspection, biosafety specialists conduct training and run tests that can impact a facility’s policies and practices. Biosafety specialists may report to a biosafety officer responsible for planning, developing, and managing biosafety programs and policies. Biosafety officers may work for a single facility or may work for a larger organization, wherein they set wide-ranging policies for preventing and responding to biosafety emergencies.
Jobs and Pay
Specific job data for biosafety specialists and officers is scarce, but BusinessWire (a Berkshire Hathaway company) has reported that openings for biosafety testing will grow 12.4 percent between 2021 and 2026.

Become a Genetic Counselor
Genetic counseling is a young but rapidly growing profession. Genetic counselors work with patients and healthcare providers to diagnose genetic risks. They conduct informational sessions with patients and families, offer counseling on any genetic risks and conditions, recommend further testing, and support inpatient and outpatient care at satellite clinics. While this is primarily a patient-facing role, genetic counselors need to utilize a solid understanding of microbiology, microbial genetics, biology, and other life sciences to facilitate their assessments.
Jobs and Pay
According to data from BLS (2022), genetic counseling jobs are expected to grow by 18 percent by 2031. The average annual wage for the 2,740 genetic counselors in US is $86,640. The percentiles for wages are:

Become a Microbiology Consultant
Microbiology consultants are the hired guns of the microbiology world. They may work in several different settings, such as laboratories, industrial companies, pharmaceutical companies, think tanks, or environmental agencies. In each instance, they assess the microbiological impacts of their client’s work and share specialized expertise to finetune operations and meet desired outcomes. A consultant’s projects may be relatively short in duration (e.g., assisting in an environmental impact report) or long (e.g., bringing a particular pharmaceutical drug all the way from inception to production).
Jobs and Pay
