This woman is the daughter of President Siebert, the president of the California Institute of Technology and his wife.

She and her parents own several dogs.

She was mentioned in "The Monopolar Expedition" (S2E23) when her father sent Sheldon on a three-month National Science Foundation expedition to the Arctic Circle, and was annoyed when Sheldon visited the family at their home in the middle of the night. Her mother eventually set their dogs on the unwelcome visitor.
