Lieutenant Peter Durst was an operations division Starfleet officer, assigned to the USS Voyager when it became stranded in the Delta Quadrant by the Caretaker in 2371.
That year, on Captain Janeway's orders, Durst escorted Lieutenant Paris from the bridge to sickbay, when it appeared Paris had altered the ship's course and had no memory of doing so. Along with Ensign Kim, he later discovered Kes and Lieutenant Tuvok unconscious in a turbolift, apparently having been incapacitated by an unknown alien. (VOY: "Cathexis")
Later that year, Durst, Paris, and the half-Human, half-Klingon Lieutenant B'Elanna Torres, were inspecting the magnesite deposits on planet Avery III, when they were taken captive by the Vidiians. Initially used as slave labor, Durst was later killed and had his organs harvested. The Vidiian scientist Sulan had Durst's face grafted over his own, in an attempt to appear more appealing to the Klingon half of Torres, from whom Sulan had separated her Human side. This attempt was unsuccessful. (VOY: "Faces")
