Taitt was born on Tau Ceti IV in 2348. At Starfleet Academy she wrote her senior year thesis on Solar Dynamics. She graduated in 2369 and earned a prestigious posting as a science officer to the USS Enterprise-D. (ST video game: Starship Creator; TNG episode & novelization: Descent)
Six weeks into her commission, during an encounter with a faction of non-Collective Borg led by Lore, Ensign Taitt manned the tactical station under the command of Commander Doctor Beverly Crusher. She hesitantly held her post, and under orders, established a frequency shift firing pattern on a Borg starship.
When Commander Crusher took the Enterprise, protected by metaphasic shielding, into a local star, it was Taitt's observations and expertise in Solar Dynamics that allowed her to use the ship's phasers to trigger a solar flare, destroying the Borg. Crusher christened the move the "Taitt Maneuver". (TNG episode & novelization: Descent)
