(written from a Production point of view)
Sara Mitich (born 26 November) is an actress who played the role of Lieutenant Commander Airiam in the first season of Star Trek: Discovery, and Lieutenant Nilsson in the second season. Remarkably, her Nilsson character was the replacement for Airiam on the bridge after the latter's death in the line of duty, and who was in the second season played by fellow Canadian actress Hannah Cheesman, having in turn replaced Mitich as such for that season.
A Canadian, Mitich studied as a child at the National Ballet School of Canada. Mitich is a graduate of the joint actor training program between University of Toronto and Sheridan College.
In addition to Star Trek: Discovery, Mitich has appeared on several other shows shot at Toronto's Pinewood Studios, including a guest appearance on Heroes Reborn, a recurring role as Lillian Moss on Murdoch Mysteries, and a recurring role as Gia on SyFy's The Expanse (alongside Trek alumn Shohreh Aghdashloo).
The child of Serbian immigrants to Canada, Mitich is an avid western horseback rider.
