Alison

From Memory Alpha, the free Star Trek reference.

Alison was an engineer aboard the Earth starship Enterprise.

When Hoshi Sato experienced an elaborate scenario while trapped in the transporter buffer, she passed Alison, who was giving instructions to Alex, in a corridor. Sato called her by name, but Alison did not respond. (ENT: "Vanishing Point")

Alison was played by Carly Thomas; her surname is given in several sources, including the IMDb, as Rhodes, but it is unknown if this name is from the script or cast list for the episode.
