Possible Career Paths


The first career option that a biologist should consider is a career in research. Research is discovery, learning how things work, learning something new that no one else in the world knows, and then telling everyone else what you've discovered. Being involved in research is an exciting way to spend your life. A career in research will hone your skills in critical thinking, creative problem solving, and persistence. Participation in research takes place at a variety of levels, and a variety of fields of biology-based research are available.

An undergraduate, or a high school student, can become involved in research. Many researchers welcome students into their research laboratories, especially during the summer, and there are many programs to support research internships. A summer research internship is an excellent opportunity to experience the excitement, as well as the process, of research. It is also a good opportunity to determine whether a career in research is a good fit for your personality. Summer undergraduate research opportunities vary from year to year; an internet search on "biology undergraduate summer research" will identify current opportunities. Graduate students in MS or PhD programs are involved in research as part of their graduate programs. A career in research is available as a research technician or research associate after earning a BS or MS degree. A PhD degree in a biological discipline opens additional doors into research careers. University professors maintain their own research laboratories in an academic setting. Doctoral-level scientists also maintain research laboratories in the pharmaceutical industry, biotechnology industry, agricultural industry, in private research institutes, and in government research laboratories such as those at the National Institutes of Health, National Institutes of Environmental Health Sciences, United States Department of Agriculture, or military health research laboratories. Research technician and research associate positions for individuals with BS or MS degrees are available in each of these settings (university research laboratories, industry, private research institutes, and government laboratories).

Biology-based researchers can choose a focus from a variety of disciplines. In the biomedical sciences, a scientist can focus on a variety of disciplines. One can further specialize within each of these fields. For example, in physiology, individuals specialize in endocrinology, the cardiovascular system, the renal system, the respiratory system, the gastrointestinal system, neurophysiology, and cellular physiology, with further subdivisions in each specialty. The range of disciplines in biological sciences is also extensive and diverse. The disciplines of biomedical and biological sciences overlap, and as in the biomedical sciences, one can further specialize in each of the broad fields of biology.

Health Care

The field of health care offers a very wide variety of career choices. Many specialties are available to a physician with either a Doctor of Medicine (MD) or Doctor of Osteopathy (DO) degree or with the combined MD/PhD degree. Osteopathic physicians are trained in the same medical and surgical therapies as allopathic physicians (MDs), with the addition of manipulative techniques for the treatment of structural problems. Physicians who hold the combined MD/PhD degree obtain training in research as well as medicine, so they are better prepared for careers in medical research. Specializations available to physicians include family medicine, obstetrics and gynecology, internal medicine, psychiatry, pathology, surgery, allergy and immunology, anesthesiology, dermatology, emergency medicine, pediatrics, medical genetics, neurology, nuclear medicine, ophthalmology, orthopedics, otolaryngology, plastic surgery, radiology, and urology, among many others. In addition to the many areas of medical specialties, there are many career options for physicians. The most common choice, and the greatest demand for physicians, is in clinical practice. However, there are many other choices for physicians. For example, a physician can develop a career in medical investigation at the Centers for Disease Control or in research at the National Institutes of Health. Alternative career paths for physicians include broadcast journalism, i.e., explaining medical advances and other clinical issues to the public on television or on the internet, the teaching of clinical medicine to medical students, and clinical research. A physician may also carry out early clinical trials in the pharmaceutical industry or more advanced clinical trials in clinical practice.

There are many other career options in health care. Opticians and orthopticians are both involved in eye care. Optometry is a doctoral-level program, whereas orthoptics, the treatment of crossed eyes/lazy eye, is a 2-yr program after a BS degree. Podiatry is a doctoral-level program in foot care for which there is a strong demand (1). Pharmacy is now a doctoral-level program. The student typically takes 2-3 yr of undergraduate work and then enters the 4-yr pharmacy doctoral program. Dentistry is also a doctoral program that one enters after completing a BS degree; there are additional specialties within dentistry, such as orthodontics. The positions of dental hygienist and dental assistant are positions in dental clinics that require less education than that of the dentist. Physical therapists and occupational therapists work with people with a variety of rehabilitative needs. Programs in physical therapy and occupational therapy are available at both MS and PhD levels. Epidemiology and public health are related careers; epidemiologists study the factors that affect the health of populations, and public health is concerned with challenges to the health of populations. Physician's assistant programs are 2-yr programs after a BS degree and are typically MS-level programs. The physician's assistant is involved in hands-on patient care and can specialize in the same broad areas of patient care as a physician. Medical technologists work in hospital or clinic laboratories and perform tests on patient samples as part of the process of disease diagnosis. Training in medical technology involves 3-4 yr of college followed by 1 yr of clinical training in a hospital training program. Within the field of medical technology are a number of specialties including microbiology, hematology, chemistry, serology, virology, blood banking, immunohematology, and forensic serology. A specialist in quality control/quality assurance is needed in all clinical laboratories and is another career option. Additional clinical laboratory/technical specialties include positions as a cytotechnician, respiratory technician, in vitro fertilization technician, sperm bank technician, radiation therapy technician, magnetic resonance technician, surgical technologist, orthotics and prosthetics patient care technician, medical appliance technician, diagnostic medical sonography technician, perfusionist, audiologist, emergency medical science technician, anesthesiology assistant, environmental science and protection technician, and X-ray technician. A genetics counselor helps families understand genetic disorders and assists those who are at high risk for genetic disorders in making decisions about expanding their families. Phlebotomists draw blood in hospitals and in clinics. In sports, physicians who specialize in sports medicine are needed, as are athletic trainers and personnel involved in sports testing. There are also careers as an acupuncturist, naturopathy practioner, or chiropractor. An internet search on any of these career choices will identify the most up to date information on requirements and training programs.

Health Care is important for the care of animals as well as people. Veterinarians specialize in large domestic animals, small domestic animals, exotic pets, zoo animals, or laboratory animals. Careers are also available as veterinary technicians or veterinary assistants. Careers as zookeepers, zoo assistants, and aquarists also build on a foundation in biology.


Another large area of careers for those with an interest in biology is education. Instructors in biology are needed at all levels of education, including elementary school, middle school, junior high school, high school, and college. Teachers for graduate students and medical students are also necessary as well as teachers with a biology-based education for technical training schools and community colleges. Schools at all levels may be either public or private. The requirements for teaching vary. A teaching certificate with a BS degree is needed for teaching at the elementary school through high school levels. Teaching at the college, graduate school, and medical school levels typically requires a PhD degree, although some colleges and community colleges hire teachers with MS-level degrees. Another significant requirement for teaching is to enjoy and appreciate students of the age group that you've chosen to teach; for example, if you don't like teenagers, don't become a high school teacher. Moreover, teaching requires focus and concentration and forces you to keep up with advances in science to ensure that you convey the latest and most exciting information to your students. A teacher must be dedicated and creative to maintain the attention and motivation of students.

Science writing

Students who have an interest in writing as well as biology may find a rewarding career in science writing. Areas of focus include the writing of feature articles for science journals such as Science and Nature, the writing of science articles for news magazines such as Time or Newsweek, and writing for local or regional newspapers. Textbooks in biological sciences must be written for students at all levels (i.e., elementary school, middle school, junior high school, high school, college, graduate school, medical school, and continuing education). Editors of those textbooks are also necessary. Technical manuals must be written for every piece of medical or research equipment used in hospitals, hospital laboratories, clinics, or research laboratories, and the writers of these manuals need to understand the biological basis of the use of the equipment. People who have an aptitude for both art and science may find a satisfying career as a scientific or medical illustrator. Other careers in this broad field include broadcast journalism, such as writing or consulting for medical dramas or serving as the host of television shows about nature, science, or animals, and creative writing, such as writing stories with a biology or medical background.

Administration and management

Another field that employs people with a biology background is administration and management. One example of a career in this field is a grants administrator at an agency that funds research. Grant funding agencies include national governmental agencies such as the National Institutes of Health and the National Science Foundation as well as nonprofit agencies such as the American Heart Association, American Diabetes Association, American Cancer Society, and March of Dimes. Administrators are needed in university Offices of Research as well as Safety and Compliance Offices. Administrators and managers who understand biology are also needed at biotechnology and pharmaceutical firms. Another example is executive director of a professional society such as the American Physiological Society.


Careers for people with a foundation in biology are also available at all levels of government, including local, state, national, and international levels of government. Positions are available in natural resource management/environmental regulation and management, including field research, in the areas of rivers and streams, fish, wildlife management (i.e., wildlife biologist), and forest management, and as county extension agents. A foundation in biology is useful for park rangers and park interpreters as well as personnel involved in water quality control and waste management. Science policy analysts, researchers, and administrators as well as lobbyists for science, technology, and education issues will benefit from a background in biology. International health organizations need biologists in administrative or research positions, and there are careers in administration and research for nonprofit public interest organizations that support a cause or issue related to life sciences or the environment at regional, national, and international levels. The federal Food and Drug Administration employs biologists for the drug approval process as well as investigators of food safety and questions of contamination of the food supply. Governments employ inspectors of meat and other food processing plants, restaurants, and imported goods of a biological nature. Governments regulate safety in the workplace through Occupational Health and Safety regulations and inspections. There are nongovernment positions in some of these fields as well; for example, there are private fisheries and wildlife biologists.


Many industries, including pharmaceutical, biotechnology, food, and agriculture industries, hire personnel at many levels with foundations in biology. Positions include market research (i.e., in the food industry), product development and testing, and sales and marketing. People with strong communication/linguistic skills may find employment in public relations in industry. The pharmaceutical industry hires drug representatives, and positions are also available for sales representatives in the agricultural industry and for companies that sell scientific reagents and equipment for research and clinical laboratories. The agricultural industry offers positions in plants and crops, angls, and biofuels industries. There are also positions in regulatory affairs and quality control in industry. Industry also employs scientific consultants. Biological entrepreneurs often found companies that develop into biotechnology or other industries.

Fields in biology-related industries such as the food industry, agricultural industry, pharmaceutical industry, and biotechnology industry and in miscellaneous biology-based careers

Miscellaneous biology-based careers

There are many careers for biologists that do not fit into the above categories. For example, biology is not a requirement to become an astronaut, but some astronauts do need to be biologists. A good brewmaster or baker needs to understand the life cycle and nutrient requirements of yeast. An interest in law and biology together may lead to a career in patent law, environmental law, or medical legal law. An interest in finance and biology may lead to a career as a financial analyst in science- or technology-based areas. Biostatisticians analyze the statistics of biological fields. Bioinformatics requires a foundation in computer analytical techniques as well as biology. This field developed from the need for analysis of the large quantities of data that emerged from the sequencing of the human and other genomes and the subsequent global biological applications of genomics and proteomics, and it has undergone significant expansion in recent years. Biofouling examines biological contamination and its prevention, from the bacterial contamination of hospital catheters to the contamination of ship's ballasts with unwanted biologicals such as zebra mussels.

Careers for Which Biology Forms the Foundation but That Require a Related Degree

Additional careers that require related degrees but for which biology forms an important foundation include anthropology, biomedical engineering, nursing, and diatetics/nutrition as well as health care administration in hospitals, clinics, and nursing homes. Paleontologists need to understand animal biology. For example, they study the origins and insertions of muscles on dinosaur bones and use that information to understand how the animals moved. The study of alcohol and drug abuse forms a foundation for positions in prevention, education, counseling, treatment, and law enforcement. Agricultural sciences also build on the knowledge of living things. Careers in agricultural science include animal science, crop science, soil science, viticulture, apiary, fish farming, dairy production, meat production, poultry science, crop consultation, crop management, and biofuels research. In addition, the United States Department of Agriculture employs researchers in both animal and plant research.

Choosing a Career

How does a student choose a career path, and how do we advise them? The first step is for students to become aware of the many career paths that are available; indeed, raising awareness of potential career opportunities for biologists is the first goal of this discussion. Biology students should then assess their personal interests and aptitudes in the various broad fields of biology (i.e., research, health care, teaching, science writing, etc.). What piques their interest? Are they more interested in plants or animals or microorganisms? How many years are they willing to devote to education? Are they willing to devote the necessary study time to achieve the required knowledge level (and accompanying grade point average)? Do they want to work outdoors or indoors? Do they want to work with lots of people? Do they want a job in a specific geographical location? Do they want a job with intellectual stimulation? Do they have other strong interests that could be combined with a foundation in biology to create a unique career? Answers to these questions will provide initial guidance in career choices.

To further refine a student's interest in a particular career, an internet search will rapidly identify information about the length of required training, level of difficulty, job demand, projected salaries, and location of training programs for that career. A very useful tool is the Occupational Outlook Handbook from the Bureau of Labor Statistics of the United States Department of Labor (1). An internet search using the terms "biology careers" will identify other useful career information. Another method of career exploration is to identify people who are employed in the career of interest and ask questions, such as how did they make their career choices, what was the training pathway, and do they find the career rewarding and worthwhile. Ask whether there is opportunity to shadow the individual, or whether there are internships that would allow hands-on experience in a field to assist the decision-making process. Students should inquire about the academic rigor required for a given career choice and should critically assess their ability to meet that standard.

The demand for personnel in a given career path is an important consideration in choosing a given path. There is strong demand for some positions such as physicians and teachers. On the other hand, there are few job openings in careers such phycology and marine biology (1). Job stability is another issue to consider. For example, research technicians with BS or MS degrees working in university research laboratories are often paid from research grants so the position may only exist for the lifespan of the grant. In contrast, the same research technician position at a pharmaceutical firm may be very stable. The Occupational Outlook Handbook (1) provides information about job stability and job demand. Salary is another decisive factor. In general, salaries are proportional to training and level of responsibility. People with a master's degree have greater responsibility and earn a greater salary than those with a bachelor's degree. Similarly, people with a PhD have greater responsibility and earn a larger salary than those with a MS degree. In health care, the physician has more years of training and the greatest responsibility and also earns the larger salary.

Many biology programs allow a student to choose a subdisciplinary track during their course of undergraduate study. The available tracks vary among Biology departments but may include a focus on cellular and molecular biology or on ecology or evolution, for example. Larger departments will have a greater diversity of options for the student. However, following an academic track narrows the training that the student receives, thereby narrowing the student's career options. This is not an issue if the student has made a career choice. However, it would be wise of the student not to focus too tightly on a career track until a career choice has been identified.


It is likely that additional career options for biologists are missing from this list, and certainly many of the specialties within broad fields are not enumerated. However, this roster should serve as a useful tool for biology students seeking information on career options and for those who assist students in searching for careers that fit their personalities and aspirations as well as their foundation in biology.
