Ryder is a female Tau'ri who was stationed at Icarus Base. In 2009, she and roughly 80 people were forced to evacuate Icarus Base during an attack against the base by three Ha'tak vessels. She ended up stranded with the others on Destiny, an Ancient spaceship located several billion light years from Earth.

During the Lucian Alliance invasion of Destiny, she used the Long-range communication device to switch bodies with Dr. Timan in order to treat the wounded. (SGU: "Intervention")
