What does a senior research investigator do?

A Senior Research Investigator specializes in conducting extensive research and analysis to develop conclusions and recommendations. Although the extent of their responsibilities depends on their place or employment industry, it usually includes adhering to guidelines and timelines, narrowing down leads to gather and analyze data, consulting with experts, and maintaining records of all procedures. As a Senior Research Investigator, it is essential to lead and serve as a role model to less experienced investigators in the joint effort to reach project goals, all while implementing the facility's standards and regulations.

What does an assistant research scientist do?

An Assistant Research Scientist assists in planning, conducting, and analyzing various research projects. They also order and manage lab inventory, materials, and equipment.
