What Does a Biologist Do?

A biologist is a scientist who studies living things and how they act and react to the environments in which they live. Numerous types of biologists exist. These include research biologists, health care biologists, environmental biologists and biology educators.

Research biologists study different groups of living organisms around the world. These types of biologists use state-of-the-art research techniques and tools to examine species such as micro-organisms, mammals, reptiles and amphibians in their natural habitats. Therefore, research biologists generally perform their work in exotic locations across the globe.

Health care biologists include physicians, veterinarians, nurses and dentists. These types of biologists prevent the spread of infectious and deadly diseases and formulate ways to enhance the health and well-being of their patients.

Environmental biologists seek out new ways to preserve the natural environments of different types of organisms. For example, zoo biologists study animals in captivity and design new preservation methods to help certain species live fuller, longer lives in their natural habitats. Conservation and management biologists further the work of these types of biologists by working with state and local authorities to develop laws and practices that protect the lives of groups of animals that cohabitate with humans or live near neighborhoods or urban developments.

Biology educators teach students and up-and-coming biologists basic and advanced biological sciences in classroom, laboratory and field settings.
