Tricia McMillan was the vice president for advanced research for the Sirius Cybernetics Corporation.
McMillan's signature was on a certificate naming Ira Graves as "humanoid of the year" in gratitude for his contributions to the Proxima Centauri Interplanetary Bowling League (and also their marching band). (TNG: "The Schizoid Man")
- McMillan's name was only visible on a piece of background artwork decorating the set of Graves's office.
