Bartel is a junior engineering officer aboard the Enterprise-D who works under Geordi La Forge during the encounter with the Dyson sphere and the rescue of Montgomery Scott in the episode Relics.
Bartel appears in the sixth-season episode Relics. She is one of Geordi La Forge's staff in main engineering when the Enterprise discovers the crashed transport Jenolen on the surface of a Dyson sphere and recovers Captain Montgomery Scott from its transporter buffer.
She is among the engineers trying to get on with their duties while the well-meaning Scott wanders the department offering advice from seventy-five years earlier, to La Forge's growing irritation.
Bartel is a small role, but she is one of the named faces that fill out the engineering team in an episode that is largely about how the work of a starship engineer has and has not changed.
