how to become a biologist

What does a Biologist do?

A biologist studies living and dead organisms. Some biologists focus in a certain area to research, such as wildlife biologists, marine biologists, or microbiologists. All of these biologists have the same fundamental education in biology and then specialize in a field they enjoy. No matter the type of biologist, they all should have a natural curiosity to learn about life.

How to Become a Biologist

how to become a biologist

A bachelor’s degree would be the minimum requirement to gain an entry-level job as a biologist. You would most likely take courses in genetics (the study of the properties or features of an organism), evolution (the study on how living organisms are thought to have developed), and physiology (the study of the way in which a living organism or bodily part functions).

Most biology students though, continue on to earn a master’s degree with a focus on the specialized area of biology they wish to pursue. You will also want as much experience as possible, so working an internship before graduating may make job hunting easier upon graduation.

Job Description of a Biologist

Depending on their field and industry, a biologist may be tasked to study how life is impacted by the environment in which it lives, or how an epidemic can spread among a species. They may split their time being in an office and workout outdoors in order to study living organisms in controlled and natural environments. They may also find themselves collecting biological specimens from organisms to study in a lab.

The would likely present their findings to others through reports and the sharing of data. They would also be the knowledge expert to make recommendations on items such as wildlife conservation or environmental policies.

Biologist Career Video Transcript

One of my favorite jobs is working with farm animals and on any center day I could go down and collect a sample in the morning time and then go back in the afternoon and collect another sample, for instance milk and then I can look at any changes that have occurred throughout the day. Our main goal is to protect human and animal health and by doing that I mean it gives us all here I think a lot of satisfaction knowing that we’re helping out everyone, including your animals at home. I guess I always really enjoyed doing science fair projects. My advice would just be to go out and try and volunteer and go to participate in the science fair and go to camps during the summer.
