What does a junior scientist do?

A junior scientist is in charge of conducting research and scientific studies while under the supervision of a more experienced scientist. Their responsibilities typically revolve around gathering and preparing samples, performing experiments and analysis, coordinating with other experts, recording all progress, reviewing results, and summarizing findings into reports and presentations. In a company setting, a junior scientist must adhere to deadlines and budgets, submitting results to senior scientists and managers. Furthermore, it is essential to uphold the policies and regulations of laboratories to maintain a safe and productive work environment.

What does a senior scientist do?

A senior scientist is usually in charge of overseeing experiments and evaluating junior scientists' performance, especially in laboratory settings. Moreover, it is also their responsibility to assess every progress report to ensure it's accuracy and validity. As a senior scientist in the field, it is essential to lead and encourage fellow scientists in their joint pursuit for scientific innovations, all while adhering to the laboratory's standards and policies.
