A junior scientist is a professional who works under the direction of a chief scientist and conducts research and scientific studies. These individuals work in a variety of industries, from chemistry, biology to pharmacology. They obtain and process samples for experiments and analysis, coordinating with other staff and scientists, document all tests, procedures and results, and author reports for management and clients. A junior scientist follows organizational procedures and protocols and must also follow budgets and meet deadlines. A junior scientist can work for a university, a private organization, or a for-profit company.
