Lieutenant Jeffrey Fratis was a Starfleet crewmember in the molecular biology department aboard the USS Enterprise-D in 2369.

This character was only mentioned in dialogue.
The script for "Man of the People" has this individual in the molecular biology department, then in the physical sciences department, and, back again, in the molecular biology department. [1] The reference to the physical sciences department was cut from the final episode.
