Tarik Ergin

Actor (Ayala) — Voyager

American performer who appeared as Lieutenant Ayala, the former Maquis crewman usually seen at a bridge or security station, in the background of Voyager across all seven seasons.

Tarik Ergin worked on Voyager as a regular background performer for the whole run of the series, making him one of its most frequently seen faces outside the main cast.
His character, Ayala, is first seen in Caretaker as a member of Chakotay's Maquis crew aboard the raider that is pulled into the Delta Quadrant. After the two crews merge he serves in security under Tuvok and is often visible at the rear bridge stations, in the transporter room or on away teams, eventually also taking the helm and tactical posts when needed.
Ayala seldom speaks, but he is addressed by name in several episodes and is among the crew marooned on Hanon IV in Basics. Ergin stayed with the role through to the finale, Endgame.
