Canadian actor who played the augmented officer Airiam in Discovery's first season and then, without prosthetics, the bridge officer Lieutenant Nilsson from the second season onward.
Sara Mitich is a Canadian actor whose other screen work includes the recurring part of Gia in The Expanse.
She was the first performer to play Airiam, the pale, mechanical-looking officer seen at the Discovery's bridge stations throughout the first season of Star Trek: Discovery. When the part was recast with Hannah Cheesman for season two, Mitich stayed with the series as a new character, Lieutenant Nilsson.
Nilsson first appears in the second season and, after Airiam's death in Project Daedalus, takes over her post at spore drive operations. She travels with the ship to the 32nd century and remains part of the bridge crew through the following seasons.
