What does a principal scientist do?

A Principal Scientist is focused on leading scientific teams and conducting research. They ensure that their teams have the resources to properly perform research tasks.

What does a postdoctoral associate do?

A postdoctoral associate is responsible for researching to support scientific claims and theories by collecting evidence and information to answer scientific questions. Postdoctoral associates must have excellent communication skills, both oral and written, to interact with people and document investigation findings. They also utilize laboratory tools and equipment for scientific researches, conduct field investigations, and interview participants. A postdoctoral associate designs comprehensive research models to discuss results with the panel and the team efficiently and accurately.
