Microbiologists
What they do
Investigate the growth, structure, development, and other characteristics of microscopic organisms, such as bacteria, algae, or fungi. Includes medical microbiologists who study the relationship between organisms and disease or the effects of antibiotics on microorganisms.
Kinds of work
- Investigative: Science, research, figuring out how things work and solving complex problems.
- Realistic: Hands-on work with tools, machines, plants or animals, often outdoors.
- Conventional: Organizing information, following clear procedures and working with data and details.
High pressure: How much pressure workers in this job report: deadlines, conflict, dealing with upset people, the cost of mistakes, responsibility for others' safety, competition and long hours. It varies a lot from one employer to the next. Source: U.S. Department of Labor worker surveys.

Career path
How people usually get into this career, from school to their first job and beyond.
Microbiologist is reachable with a bachelor's degree. Most people spend about 6 months to 1 year in an entry-level lab job before taking on microbiologist work, so the full path from starting college usually takes about 5 to 6 years.
Bachelor's degree in microbiology, biology, or a related science
4 yearsYou learn how microbes work, how to run lab experiments safely, and how to read scientific papers, which are the core skills the job needs.
Biological Technician
6 months to 1 yearYou run lab tests, grow cultures, keep careful records, and follow lab procedures under a scientist's direction, which builds the hands-on experience employers look for.
Microbiologist
OngoingYou investigate how microorganisms grow, spread, and affect people, plants, or the environment, and you design and run your own experiments.
Where it can lead
Senior Microbiologist
3 to 5 years of experience firstYou take on more complex projects, mentor newer staff, and often lead parts of a research or testing program.
Medical Scientist
6 to 8 years of experience firstYou move toward research on diseases and treatments, which usually requires a doctoral or professional degree.
What you can do now
Ideas for high school and college students.
In high school
- Take biology, chemistry, and mathThese classes give you the foundation for understanding microbes and for the lab math you will use later.
- Enter a science fairDesigning your own experiment, such as testing which household cleaners kill bacteria, teaches you the scientific method.
- Volunteer at a hospital, clinic, or science museumSeeing lab or science work up close helps you decide whether this career fits you.
- Get a part-time job or tutoring roleWork that needs careful attention to detail, like a pharmacy or grocery job, builds reliability that labs value.
- Join a science or biology clubClubs give you teamwork practice and a chance to work on projects with teachers and peers.
In college
- Major in microbiology or biologyA microbiology major gives you direct coursework in bacteria, fungi, and viruses, which is the core knowledge for this job.
- Join an undergraduate research labWorking alongside a professor gives you real lab experience and a reference that employers and graduate programs value.
- Apply for a lab internship or campus lab jobPaid lab work during school counts toward the hands-on experience that most microbiologist roles need.
- Take statistics and a computer science or data analysis classLab work produces lots of data, and knowing how to analyze it makes you more useful to employers.
- Get lab safety or biosafety trainingMany labs require this training, and having it on your resume shows you can work safely with microorganisms from the start.
Tips for getting started
- Look for paid or volunteer lab work during college, such as a campus research lab, a hospital lab, or a public health lab. Hands-on experience matters a lot for this career.
- Get comfortable with lab safety rules and basic lab tools like pipettes, microscopes, and sterile technique, since employers often expect these skills from day one.
- Talk with a microbiology or biology professor about undergraduate research. It can lead to a reference letter and helps you see whether you enjoy the daily work.
