Crewman Pierce was a Starfleet engineer assigned to Columbia NX-02 in 2154.

In that year, Commander Charles Tucker, who had transferred from Enterprise NX-01, ordered Crewmen Pierce and Biggs to recalibrate the ship's field stabilizers as part of an effort to align Columbia's dilithium matrix to within 0.3 microns. (ENT: "Affliction")

Pierce was played by an unknown actress.
In the final draft script of "Affliction", this character was instead assigned, along with Ensign Rivers, to start work on Columbia's injector assembly.
The novel Gods of Night gives her the first name Daria (β).
