A biologist is a scientist devoted to and producing results in biology through the study of organisms. Typically biologists study organisms and their relationship to their environment. Biologists involved in basic research attempt to discover underlying mechanisms that govern how organisms work. 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. Technicians perform specialized tasks using laboratory equipment.
There are many types of biologists. Some deal with the macroscopic world and other with the microscopic. There is much overlap between different fields, and it is often hard to classify a biologist as only one of them. Some of the fields are:
* Animal
* Biochemistry
* Cell
* Developmental
* Ecology
* Evolutionary

Below is the list of the areas on which a biologist works most of the times:

Dear Friend, the job aof a biolgist is very challenging and interesting, because biologist has to interact with students, colleagues, superiors and may be clients. The biologist could be a botanist (working on plants), a zoologist (animal related studies), microbiologist (deals with microorganisms), biochemist (study the biochemical aspects of living beings), environmental scientist (study the environmental aspcts) and there are many more disciplines related to biology.

The important key areas for a biologist depends upon his nature of jobs. If a person in academecia, then he has to deal most of the time in teaching and interacting with students. He spend time to prepare the topics for his class. Before going to class agian going through the topic. He has to also guide the students about their research work, parctical classes.

The biologist is also supposed to do research, for this he writes research proposals to funding agencies. After getting projects he carried out research activities with the help of his research fellows. The out come of research activities are published in the form of research papers.

Besides these activities the biologist also involved in attending the confrences, workshops and training programs. The senior biologist also looks after the administrative aspects of the department or institution. In admisnistrative jobs, there is less teaching and research activities. Along with these activities the biologist also do other waork as looking after exam, preparing questions and then checking answer books. The quality assurance duities of the department and regular process of meetings with students, colleagues and seniors. In nut shell the biologist keeps himself or herself busy during the office time.
