Juliana Tainer

Juliana Tainer, born Juliana O'Donnell, was a human scientist. She lived at Omicron Theta, where she married Dr. Noonien Soong. When the Crystalline Entity attacked, O'Donnell was seriously injured and slipped into a coma. Dr. Soong transferred her memories into an android meant to be indestinguishable from a human. O'Donnell, remaining unaware of her new state, became frustrated with Soong's devotion to his work above all other things and left him in 2365. (SNW VII: "Life's Work")
