One of big question usually asked by beginner is that What does a bioinformatics specialist do? Answer to this question is little hard, because every one has their own goal in bioinformatics but, Bioinformatics specialists help companies and researchers managing, processing, and analyzing genomics data and molecular data. They create and maintain databases and large data to contain the information, and design or select algorithms to process, analyze, visualize, and interpret it. They may also use data mining techniques or statistical software for finding pattern, problems and solutions. They may use their computer programming skills to extend the capabilities of software packages, Web tools, databases, and database queries.

Bioinformatics specialists may process data sets to auto-enter them into databases, then run tests to check the integrity of the data entered. They also check the quality of analysis outputs to ensure that the algorithms and methods used are adequate and appropriate for the task at hand.

Bioinformatics specialists work with the researchers in laboratories and staff they support to determine their data storage needs and analysis requirements. They also help with database-related aspects of research, such as devising appropriate queries. Some even assist with experimental design and data collection. Since their work is a critical part of the research process, they may be called upon to help prepare reports and scientific journal articles. They must also document all database changes, modifications, and technical issues, as they may affect the research process and quality because of manipulation in data for a better result. They must keep up with new computational methods and computing technologies and algorithms and mathematical solutions in order to support their researchers.

While most bioinformatics efforts focus on the human genome, bioinformatics specialists are increasingly needed to support wildlife biologists and environmental scientists. When applied wildlife biology and ecological modeling, bioinformatics supports population biology, conservation genetics, and the survival of endangered species.
