In 1994, Lien was given a role as Kes on Star Trek: Voyager. Kes was an Ocampan, whose specialty is that they live for 8 or 9 years. In season four, she was given up to bring on Jeri Ryan. In 2000, Lien returned for a scene in season six, where she played a more established adaptation of herself with god-like powers.
After Voyager, she got a role alongside Edward Norton in American History X. In 1998, she gave voice to The Lion King II: Simba’s Pride, and Men in Black: The Series.
Then she got married to Phil Hwang in 2002 who was a writer and a filmmaker. She bid goodbye to acting and voice work. In 2010, Lien told Startrek.com she was taking school courses to end up a nutritionist or dietician.
In 2012, Lien got arrested for domestic assault. In 2015, Lien was arrested for evading arrest, resisting arrest, reckless endangerment and aggravated assault. No doubt she will turn up Gary Coleman of Star Trek.
