Tabatha Brisk was the former Chief Medical Officer aboard the ISS Arcadia in the mirror universe. Like most Terrans, she was born into slavery, but was adopted as a child into one of the "privileged" Terran families who enjoyed higher social status over other Terrans in the Klingon-Cardassian Alliance, allowing her to learn medical knowledge and become a doctor. Wooed by Stephen April, she joined the rebellion against the Alliance and played a formative role in the new Empire's organization, with regards to medical programs for the new Starfleet.
