Science Officer
From Star Trek : Freedom's Wiki
Serve in the Science Department on starships or starbases in Starfleet. As the name implies, science officers are responsible for observations, research, and experiments in any of the sciences, including mathematics, statistics, physics (physical and temporal), chemistry, botany, zoology, geology, cosmology, and others. Some science officers specialize in a particular discipline. The department has some overlap with the medical department in terms of microbiology, xenobiology, and life sciences.
