From The Stargate Omnipedia
Paramedic assigned to Icarus Base
under Dr. Simms
, now the only individual with medical training aboard the Destiny
. Her friends know her as T.J.
Prior to the evacuation of Icarus Base, Johansen requested a transfer or discharge from the program, having won a scholarship to study medicine at a Seattle university.
Tamara had an extramarital affair with her commanding officer on the base, Colonel Everett Young, resulting in a pregnancy. Unaware of the baby, Young severed the affair in favor of his wife. These circumstances likely prompted this transfer. It is unclear if I.O.A. representative Camille Wray granted her request, as T.J. stayed at Icarus two weeks beyond her required tour of duty.
Several months into her pregnancy T.J. lost the baby after she was accidentally shot in the abdomen. While unconscious she found herself on the planet where Dr. Caine and other crew members had stayed behind, her daughter alive and healthy. She named the child Carmen, after the baby's grandmother (probably T.J.'s mother). Caine told her that the advanced alien species who created that solar system brought her there, saving her child's life and bringing her there for them to take care of. But it's not clear if T.J. believes the experience was real -- and that her daughter is alive.
The resources of Destiny severely limited, Johansen must draw upon all of her medical knowledge and experience to provide unconventional solutions. On board the Ancient ship T.J.'s medical expertise -- though far from expert -- has proved invaluable. In addition to caring for injuries she has successfully diagnosed alien ailments, conducted surgery, and synthesized the cure to a virus and an anesthetic from the venom of an alien creature.
