What do biologists do?

There are several career paths you can follow as a biologist, including:

Research: Research biologists study the natural world, using the latest scientific tools and techniques in both laboratory settings and the outdoors, to understand how living systems work. Many work in exotic locations around the world, and what they discover increases our understanding of biology and may be put to practical use to find solutions to specific problems.

Applied: Many biologists have jobs doing biology. Department of Natural Resources workers, field workers for research projects, genetic technicians, greenhouse managers, workers in zoos and aquaria: All of these are ways in which a biology major is applied to solving a problem.

Health care: Biologists may develop public health campaigns to defeat illnesses such as tuberculosis, AIDS, cancer, and heart disease. Others work to prevent the spread of rare, deadly diseases, such as the now infamous Ebola virus. Veterinarians tend to sick and injured animals, and doctors, dentists, nurses, and other health care professionals maintain the general health and well being of their patients.

Environmental management and conservation: Biologists in management and conservation careers are interested in solving environmental problems and preserving the natural world for future generations. Park rangers protect state and national parks, help preserve their natural resources, and educate the general public. Zoo biologists carry out endangered species recovery programs. In addition, management and conservation biologists often work with members of a community such as landowners and special interest groups to develop and implement management plans.

Education: Life science educators enjoy working with people and encouraging them to learn new things. Employment opportunities include:

New directions in biological careers: There are many careers for biologists who want to combine their scientific training with interests in other fields. Here are some examples:

  • Biotechnology: Biologists apply scientific principles to develop and enhance products, tools, and technological advances in fields such as agriculture, food science, and medicine.
  • Forensic science: Forensic biologists work with police departments and other law enforcement agencies using scientific methods to discover and process evidence that can be used to solve crimes.
  • Politics and policy: Science advisors work with lawmakers to create new legislation on topics such as biomedical research and environmental protection. Their input is essential, ensuring that decisions are based upon solid science.
  • Business and industry: Biologists work with drug companies and providers of scientific products and services to research and test new products. They also work in sales, marketing, and public relations positions.
  • Economics: Trained professionals work with the government and other organizations to study and address the economic impacts of biological issues, such as species extinctions, forest protection, and environmental pollution.
  • Mathematics: Biologists in fields such as bioinformatics and computational biology apply mathematical techniques to solve biological problems, such as modeling ecosystem processes and gene sequencing.
  • Science writing and communication: Journalists and writers with a science background inform the general public about relevant and emerging biological issues.
  • Art: The illustrations in your biology textbook, as well as in newspaper and magazine science articles, were created by talented artists with a thorough understanding of biology.

How can I prepare for a career in biology?

If you are interested in becoming a biologist, there are some things you can do along the way to prepare yourself.

In high school

  • Take courses in math and science. Biologists need a solid understanding of math, chemistry, physics, and of course biology. Taking these courses in high school will provide you with an excellent background and allow you to explore what scientists do.
  • Talk to biologists. If you are interested in a health care career, visit doctors or veterinarians and ask for a moment to talk to them about their careers. If you are interested in outdoor work, talk to park rangers, land managers, and other professionals in your area.
  • Explore your college options. Deciding where to go to college and what to study can be a daunting task. Research schools of interest. Talk to your guidance counselor, as well as to admissions counselors, faculty, and current students at these schools. There are excellent programs at a wide range of institutions, from large research universities to small liberal arts and community colleges.
  • Have fun! While studies are important, remember to get out and enjoy yourself as well. Participate in any extracurricular activities of interest: a school club, a science fair, a sports team, or volunteer work. You'll learn teamwork while developing leadership and social skills, making you stand out not only as a future biologist but also as an individual.

In college

  • Talk to your advisor. Your faculty advisor or guidance counselor is a great source of information for advice on classes to take, career path options, and job opportunities.
  • Consider how long you want to be in school. For some biology jobs, a two-year college degree is sufficient. But most life science careers require at least a bachelor's degree and often an advanced degree, such as a master's degree. Research jobs typically require a doctorate, which may take five or six years of intense and demanding training.
  • Ask your professors about part-time jobs. Many professors hire student assistants to help with library, field, and laboratory research. Not only will you earn some money and experience, but you'll also develop a professional relationship with someone who can give you career advice and write letters of recommendation.
  • Find summer internships. Internships are a good way to learn about a career, make contacts, and gain experience in biology. Some internships may provide opportunities to do an original research project — a very rewarding experience that will show you how science works and get you thinking about graduate school.
