(") After working hard, Jadzia was initially rejected for joining and eliminated from the program by her field docent Curzon Dax in 2364.
The reason he gave for this decision was that Jadzia lacked purpose.
She was acquainted with Captain Keogh, though the two did not get along.
He was briefly joined with the Dax symbiont, becoming Verad Dax before he was apprehended and Dax was rejoined with Jadzia.After Curzon's initial decision, she successfully re-applied that same year and became the only Trill in history to successfully complete the program after having been rejected.She described herself as going as a "different woman" into the program and "tore through it with a passion".(") Prior to her joining, Jadzia attended Starfleet Academy and applied to the Trill Symbiosis Commission for joining after graduation.While at the Academy, she earned Premier Distinctions in astrophysics, exoarchaeology, exobiology and zoology.
She was a Starfleet science officer who served on space station Deep Space 9 under the command of Captain Benjamin Sisko.
