A biologist studies living organisms and their relationships with the environment. While all biologists study life in some form, there are numerous types of biology careers. The majority of biologists fall into one of two main categories: macroscopic or microscopic. Microscopic biologists study organisms that can’t be seen with the naked eye. They research organisms like bacteria, molecules, or specific cells. In contrast, a macroscopic biologist will research living things that are measurable and easily visible, like plants and animals. The specific duties of a biologist will vary depending on the company and chosen industry. As a biologist, you can expect to use data and research to make advancements in your field and prepare reports on your findings. Biologists play a key role in the medicine and in the agricultural industry, improving treatments, processes, and systems. Biology is useful and impactful across a broad spectrum of areas, and most biologists choose to specialize in a dedicated field. From marine biologists to molecular biologists, there are plenty of opportunities to find a specialty that suits you and your interests.
