Duties

Microbiologists generally work in some way to increase scientific knowledge or to utilise that knowledge in a way that improves outcomes in medicine or some industry. For many microbiologists, this work includes planning and conducting experimental research projects in some kind of
laboratory A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physic ...
setting. Others may have a more administrative role, supervising scientists and evaluating their results. Microbiologists working in the medical field, such as clinical microbiologists, may see patients or patient samples and do various tests to detect disease-causing organisms. For microbiologists working in academia, duties include performing research in an academic laboratory, writing grant proposals to fund research, as well as some amount of teaching and designing courses. Microbiologists in industry roles may have similar duties except research is performed in industrial labs in order to develop or improve commercial products and processes. Industry jobs may also include some degree of sales and marketing work, as well as regulatory compliance duties. Microbiologists working in government may have a variety of duties, including laboratory research, writing and advising, developing and reviewing regulatory processes, and overseeing grants offered to outside institutions. Some microbiologists work in the field of

regulations. Clinical microbiologists tend to work in government or hospital laboratories where their duties include analyzing clinical specimens to detect microorganisms responsible for the disease. Some microbiologists instead work in the field of science outreach, where they develop programs and materials to educate students and non-scientists and encourage interest in the field of microbiology for the younger generation .


Education

Entry-level microbiology jobs generally require at least a
bachelor's degree A bachelor's degree (from Middle Latin ''baccalaureus'') or baccalaureate (from Modern Latin ''baccalaureatus'') is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to six ...

, followed by more specialized courses in sub-fields of interest. Many of these courses have laboratory components to teach trainees basic and specialized laboratory skills. Higher-level and independent jobs like a clinical/Medical Microbiologist in a hospital or medical research centre generally require a Masters in Microbiology along with PhD in any of the life-sciences (Biochem, Micro, Biotech, Genetics, etc) as well as several years experience as a microbiologist. This often includes time spent as a
postdoctoral researcher A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pu ...
wherein one leads research projects and prepares to transition to an independent career. Postdoctoral researchers are often evaluated largely based on their record of published

s, as well as recommendations from their supervisors and colleagues. In certain sub-fields of microbiology, licenses or certifications are available or required in order to qualify for certain positions. This is true for clinical microbiologists, as well as those involved in food safety and some aspects of pharmaceutical/medical device development.


Job outlook

Microbiologists will continue to be needed to advance basic science knowledge and to contribute to development of pharmaceuticals and biotechnology products. However, job prospects vary widely by job and location. In the
United States The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territori ...
, the Bureau of Labor Statistics predicts that employment of microbiologists will grow 4 percent from 2014 (22,400 employed) to 2024 (23,200 employed). This represents slower growth than the average occupation, as well as slower growth than life scientists as a whole (6 percent projected).
