T'rb was a male Bolian who was a Federation Starfleet science officer in the late 24th century. In June 2376, Ensign T'rb was assigned to the USS Defiant during its three month mission of exploration in the Gamma Quadrant. Once first contact had been made with the Vahni Vahltupali, T'rb visited their natural history museum. Ensign Gerda Roness joked that only an emergency transport would get the fascinated science officer out of there. (DS9 - Mission Gamma novel: Twilight)
