Dav Miller is an engineer. He and his wife, Judy, are quiet, observent Jewish people, very good at their jobs and in their relationship. The only flaw Dav has is a tendency to harangue other Jewish crewmembers about their shared faith. He and Judy have one child, a daughter named Miriam. They transferred off the Enterprise late in Judy's pregnancy, but are now working to be assigned to one of the Nest ships.
