In 1994, she was cast as the Ocampa alien Kes on Star Trek: Voyager, although she was let go from the series after the third season.
Her departure in 1997 coincided with the casting of Jeri Ryan as Seven of Nine, and it is speculated that the producers felt the new character was more worthy of exploration.
She is allergic to spirit gum, an adhesive commonly used in affixing special effects prosthetics, which was a major factor in her departure from Star Trek: Voyager.
