An engineering crewman aboard Enterprise NX-01, played by Joseph Will, who is one of the people seized by the web-like alien organism in the episode Vox Sola.
Crewman Michael Rostov works in engineering under Commander Tucker on Enterprise NX-01. He was played by Joseph Will and is one of the handful of lower-ranking crew members to recur during the first two seasons.
He is most prominent in Vox Sola. Sent to investigate a fault in a cargo bay, he is the first to be caught by a tendrilled lifeform that has come aboard, and is held there with Archer, Tucker and others until Hoshi Sato manages to communicate with it.
He is seen again in The Crossing, when non-corporeal aliens begin taking over the bodies of the crew.
