Angelo Tassoni
From Memory Alpha, the free Star Trek reference
Angelo Tassoni was a crew member on the USS Equinox when the ship was stranded in the Delta Quadrant by the Caretaker's array.
He was transfered to the USS Voyager when the Equinox was destroyed. Captain Kathryn Janeway reduced Tassoni and the five other remaining Equinox crew to active crewman rank, and told them that they needed to earn her trust, she also put them under strict supervision. (VOY: "Equinox", "Equinox, Part II")
Tassoni was played by an unknown actor.
