Perhaps better known for her role on Everwood, Niznik played the Trill helms-person Kell Perim in Star Trek: Insurrection. She was only 52. https://variety.com/2019/tv/news/stephanie-niznik-dead-dies-star-trek-everwood-1203266197/amp/
It wasn't a large role, but she did make a good impression with it. She also played the alien apparition who appeared to Captain Archer in Enterprise's Rogue Planet.
This was the first thing I saw her in. IMDb says she hasn't been in anything in the last 10 years. I wonder what happened.
RIP Stephanie. We'll never forget you as Ensign Kell Perim in "Insurrection." This is probably the most memorable moment of her playing Ensign Perim: https://i.imgur.com/0sMdYo0.gif

Very sorry to hear that. Her character did get much more background and exposure in the A Time To...novels which was nice. Gave me a greater appreciation for her role in Insurrection. It's always nice when a character you know little about on screen gets fleshed out.
