Mia Bayer

Mia Bayer is a Fleet Chief working on Talos I during Prey (2017)

Background
During the Typhon outbreak, she hid in the Flight Control room and ordered the Grav Shafts to be shut down so the Typhon don't make it up there.

She died from suffocation along with other surviving members (at least the ones who weren't killed by the Typhon) when the Technopath reversed the Oxygen system by pulling the air from it

Prey (2017)
Morgan Yu finds Bayer's corpse inside Flight Control in Shuttle Bay. She carries burnt circuit board and spare parts. Shotgun shells and a TranScribe are laying on the desk in front of her.
