If you answered yes to several of these questions, biology could be a promising career for you. Embarking on a career in biology has many paths; each with its own rewards and challenges. Which path you take will have as much to do with your personality as it does your intellectual curiosity and interests. Being a biologist can be a fulfilling and exciting profession if your own personal goals, talents and interests match the activities of biologists.
What do biologists do?
Research. Conducting research can be a satisfying and challenging experience that runs the gamut from the exhilaration of new discovery to the day-to-day tedium of repetitive experiments. Depending upon their interests and place of employment, biologists may engage in basic or applied research.
Basic research is pure science motivated by the need to answer questions about how organisms function or evolve. It is often curiosity-driven and it allows scientists to create new knowledge. Basic research is extremely important to society, because it fosters the development of new theories – conceptual frameworks that help scientists understand and explain the living world, and it provides the basis for applied research.
Applied research is characterized by the application of concepts and is driven by the need to solve problems that are often of immediate concern to society, medicine or industry. The distinction between basic and applied research is often blurred, however, because a scientist might be engaged in both enterprises as one flows logically from the other. For example, scientists can apply knowledge of the basic biology and ecology of an insect pest to develop an integrated pest management strategy that will minimize pesticide use and environmental damage.
Teaching. Teaching offers biologists personal as well as intellectual rewards. As faculty, biologists may teach in a formal classroom setting or serve as mentors in a research laboratory. The teaching setting may even extend beyond the boundaries of the classroom into the community or the environment.
Informal Education. Biologists may also communicate science to the public. For example, they might:
- create educational exhibits for museums, zoos or aquaria.
- give public lectures or workshops.
- write science articles published in newspapers, magazines and books.
- produce educational software or multimedia applications.
- develop educational films and television programs.
Administration. Biologists in academe, industry and government are often in positions that require many other skills in addition to their biological knowledge. Management and administrative positions require excellent communication skills and business knowledge, as well as information management and computer skills.

How much do biologists earn? Will I be able to support a family?
In general, biologists earn middle-income salaries that are adequate to support a family and enjoy a comfortable standard of living. Salaries vary, of course, depending upon training, level of experience, and geographical area.
What major should I choose?
The undergraduate major you choose will depend on the degree programs offered by the college or university you attend and your area of interest. Many academic institutions offer the Bachelor of Arts and the Bachelor of Science degrees in Biology, while others offer topic-specific degrees such as Bachelor of Science degrees in Botany, Microbiology, Zoology and Cell/Molecular Biology.
Visit with an academic counselor to learn about available degree plans and departmental emphases for each college or university you consider. Many biology departments across the country are redrawing their academic boundaries; some are splitting molecular, cellular and developmental biology from organismal, ecology and evolutionary biology; some schools are merging departments traditionally divided on taxonomic grounds – botany and zoology; and some are drawing departmental lines based upon level of analysis – molecular/cellular versus organismal/ecosystem. Even though biology is an integrative science that should be unified into an interrelated network of subdisciplines, one large life science department is often not practical to manage, as conflicts among faculty interest groups arise over career standards, funding resources and methodologies.
What are some of the subdisciplines in biology?
Biological sciences include so many approaches to studying living organisms that it is not easy to describe them all. Biologists may specialize on a specific group of organisms or may take a comparative approach to study certain life processes. Life may be studied at various levels – molecular, cellular, organismal, population, community or ecosystem. Some bioscientists are parts of multidisciplinary teams that tackle several aspects of the same problem. Ultimately, however, it is the nature and scope of the research problem that determines which techniques and research strategies are appropriate.
New subdisciplines in biology will surely emerge as a consequence of rapidly changing technology and the appearance of new global health and environmental problems. Today, students embarking on a new career in biology would be well advised to position themselves to be adaptable to change; specialization in any one field of biology is no guarantee that it will be a lifelong endeavor.
Modern biology is integrative in the sense that a biological question may be studied from different fields as diverse as biochemistry and behavior, and from different vantage points ranging from molecules to whole organisms and even ecosystems. Many biologists use a comparative approach, comparing structures, organisms, ecosystems, etc. This is necessary to understand biodiversity and evolutionary change.
If I decide to become a biologist, what classes should I take?
Biologists tend to be well-rounded in the sciences and typically complete chemistry (through organic), physics, biochemistry and mathematics courses in addition to their biology courses. The upper-level biology courses taken by biology majors depend upon their degree requirements, courses available and the student’s own area of interest. Some biologists prefer to become broadly trained at the undergraduate level and some prefer to specialize immediately. This usually determines the biology courses a student elects to take.
Are there other activities I should participate in besides formal classes?
Selecting a career that matches your personal goals and talents requires that you have enough background information to make an informed choice. Students with unrealistic expectations can be disappointed to find that the coursework, dedication and years of study required to become a scientist are not what they bargained for or contribute to the lifestyle that they want. Take the initiative early to explore career options.
Research different occupations and employers
that hire biologists.
- Arrange to “shadow” someone in a career that interests you. Spend several days with him/her in the workplace to witness firsthand what it would be like to have a similar career.
- Review current job listings to see what characteristics employers want. Go to the library or Internet and access the classified advertisements in trade journals. Refer to the section at the end of this brochure for a listing of some helpful titles and Web sites.
Acquire practical experience through:
- Volunteer work.
- Summer college courses.
- Summer internships for high school students or undergraduates. Many colleges and universities offer summer internships, which are excellent opportunities to interact with scientists and gain practical research experience.
- Visit Peterson’s Education Center on the Internet to do a quick search of summer programs. (http://www.petersons.com/summerop/ssector.html)
- Check with the undergraduate advisor for summer programs offered locally. Many research faculty have stipends for summer research in their laboratories or in the field.
- The Howard Hughes Medical Institute (HHMI) funds research experiences for both high school students and undergraduates. Search their web site for “summer programs.” (http://hhmi.org/search)
- The National Science Foundation not only funds summer internships but also maintains a Web site with links to other summer programs. (http://www.nsf.gov/home/bio/start.htm)
- Undergraduate research. Become involved with research as an undergraduate – preferably during the junior and senior years. Most universities have courses that may be listed as independent studies, problems or undergraduate research. An important part of the research experience is sharing your results through professional meetings and publishing papers. Most states have an Academy of Science with a Junior Academy specifically designed for high school students and college undergraduates. These are excellent opportunities to present your project results, meet faculty from state universities and hear their research presentations. Additionally, increasing numbers of undergraduate researchers present the results of their studies as talks and posters at the SICB Annual Meetings.
How much training will I need? Should I go to graduate school?
It depends upon your career goals. In general, you have the following options.
Bachelor’s degree. Some students directly enter the workplace after completing their undergraduate degrees and have happy, productive careers. Many take entry-level positions in industry or government or become K-12 teachers.
Master’s degree. Others go into graduate programs to build their knowledge to higher technical levels. A master’s degree prepares you as a professional in a technical field or gives you the background to do more advanced study. People with master’s degrees may become secondary school teachers, junior college instructors, or laboratory technicians in industry, government and universities.
Ph.D. degree. The Ph.D. degree is a research degree that allows you to add to the body of existing scientific and technical knowledge. If your career goals include directing research or teaching at the college or university level, you should strongly consider entering a doctoral program.
Postdoctoral Study. If you desire a research career in academe, it is often necessary to spend one or more years beyond the Ph.D. in postdoctoral study. If the field is very competitive, it is not unusual for scientists to have several postdoctoral positions in succession before they find suitable academic positions.
People who complete graduate studies share a strong commitment to their discipline and are prepared to face the high level of competition for grant money necessary to fund research. They enjoy learning, solving problems, discovering new facts and are excited about what they do.
How do I apply to graduate school?
- The best source of information on application procedures is your own university.
- Check with your undergraduate advisor. As someone who has been through the process, this person is knowledgeable and can direct you to available resources.
- Gather information on graduate schools. In addition to talking to your academic advisor, check the reference area of your university library and the Internet. One valuable resource is Peterson’s Education Center. (http://www.petersons.com/)
- Take the Graduate Record Exam (GRE). This exam is required by most graduate programs and should be completed during the junior or senior year. Some graduate programs also require an advanced test in a specialty. Once you decide on a graduate program, check the entrance requirement to determine if an advanced test is required.
- Write to the schools that interest you and ask for information and application materials. Examine these materials carefully to ensure you complete all of the requirements for admission by the stated deadlines. Meeting deadlines is good practice, since missing deadlines in graduate school can have
What is the best major to get into medical/dental school?
Any major is fine as long as you complete and do well in certain courses. Examine your curriculum carefully and plan a course of study that meets the requirements for your bachelor’s degree, as well as for admission to the medical or dental school of your choice. Most medical schools require introductory courses in:
Be aware that the competition to be accepted into medical school is very tough – there are four applicants for every spot in entering medical school classes. Early commitment and devotion to becoming prepared is a must!
