Biologist

A biologist, or biological scientist, is a scientist who studies living organisms, often in the context of their environment. Biologists involved in fundamental research attempt to explore and further explain the underlying mechanisms that govern the functioning of organisms. Biologists involved in applied research attempt to develop or improve more specific processes and understanding, in fields such as medicine, industry and agriculture.
While "biologist" can apply to any scientist studying biology, most biologists research and specialise in specific fields. In this way, biologists investigate large-scale organism interactions (ecology), whole multicellular organisms, organs, tissues, cells, and small-scale cellular and molecular processes. Other biologists study less direct aspects of life, such as phylogeny and evolution.
As with other scientists, biologists conduct research based on the scientific method, with hypothesis formation, experimentation and documentation of methods and data.
There are many types of biologists. Some work on microorganisms while others study multicellular organisms. There is much overlap between different fields of biology such as botany, zoology, microbiology, genetics and evolutionary biology, and it is often difficult to classify a biologist as only one of them. Many jobs in biology as a field require an academic degree. A Ph.D. or its equivalent is generally required to direct independent research, and involves a specialization in a specific area of biology. Many biological scientists work in research and development. Some conduct fundamental research to advance our knowledge of living organisms, including bacteria and other pathogens. This research enhances understanding and adds to the scientific database of literature. Furthermore, it often aids the development of solutions to problems in areas such as human health and the natural environment. These biological scientists mostly work in government, university, and private industry laboratories. Many expand on specialized research that they started in post-graduate qualifications, such as a PhD.
==Research==

Biological scientists who work in applied research or product development often use knowledge gained by basic research to further knowledge in particular fields or applications. For example, this applied research may be used to develop new pharmaceutical drugs, treatments, and medical diagnostic tests; increase crop yields; and develop biofuels. They usually have less freedom than basic researchers to choose the emphasis of their research, and they spend more time working on marketable treatments to meet the business goals of their employers. Biological scientists conducting applied research and product development in private industry may be required to describe their research plans or results to non-scientists who are in a position to veto or approve their ideas. These scientists must consider the business effects of their work.
Some biologists conduct laboratory experiments involving animals, plants or microorganisms. However, some biological research also occurs outside the laboratory and may involve natural observation rather than experimentation. For example, a botanist may investigate the plant species present in a particular environment, while an ecologist might study how a forest area recovers after a fire.
Swift advances in knowledge of genetics and organic molecules spurred growth in the field of biotechnology, transforming the industries in which biological scientists work. Biological scientists can now manipulate the genetic material of animals and plants, attempting to make organisms more productive or resistant to disease. Basic and applied research on biotechnological processes, such as recombining DNA, has led to the production of important substances, including human insulin and growth hormone. Many other substances not previously available in large quantities are now produced by biotechnological means. Some of these substances are useful in treating diseases.
Those working on various genome (chromosomes with their associated genes) projects isolate genes and determine their function. This work continues to lead to the discovery of genes associated with specific diseases and inherited health risks, such as sickle cell anemia. Advances in biotechnology have created research opportunities in almost all areas of biology, with commercial applications in areas such as medicine, agriculture, and environmental remediation.
