Ti'Ana was a female Vulcan-Betazoid hybrid Starfleet officer in the late-24th century.
In May 2381, Ensign Ti'Ana served aboard the Vesta-class USS Quirinal as a junior science officer when it was assigned to Project Full Circle.
In September 2381, the Quirinal became trapped in a fracture between normal-space and the Omega Continuum. Ti'Ana was among the crew that were beamed to safety aboard the USS Achilles, then transported to the Alpha Quadrant by the Mulciber-class starship for reassignment. (VOY novel: The Eternal Tide)
In 2382, Ensign Ti'Ana was assigned to the USS Vesta and returned to the Delta Quadrant as part of Project Full Circle. (VOY novel: Protectors)
