A biologist is a scientist who studies living organisms. Biologists involved in basic research attempt to discover underlying mechanisms that govern how organisms function. Biologists involved in applied research attempt to develop or improve medical, industrial or agricultural processes. Some biologists work in management positions coordinating or supervising research.
Astrobiologists, also known as exobiologists, life scientists, and space scientists, study the origin of all life formsâfrom a simple one-celled organism, to plants, to human beings. They study and research the evolution, distribution, and future of these life forms, on Earth as well as on other planets in our solar system and beyond. Many astrobiologists are employed by the National Aeronautics and Space Administration (NASA) and other government-funded agencies. They are also employed at private research institutions and colleges and universities.
