Collins was born in Tycho City, Luna in the 2350s. While she was a child, Collins and her father used to put on suits every month, hike out across the Sea of Clouds, and stop on the western rim to watch the intense lunar dawn. She would describe the experience by saying, "I felt like I met God every morning."
During her time at Starfleet Academy, she became a member of the elite cadet group Red Squad. In 2373, she was assigned along with Red Squad to the USS Valiant as part of a training exercise. However, this was just prior to the outbreak of the Dominion War, and the ship was caught behind enemy lines. In an ensuing battle, the officers on the ship were killed, and Collins received a field appointment to acting chief petty officer by fellow Red Squad cadet Tim Watters, who had been given command of the Valiant. She spent eight months in this position while Watters continued the officer's mission.
When the ship encountered Jake Sisko and Ensign Nog under attack in the USS Shenandoah, she transported both of them to the Valiant. The two would then accompany the ship on its mission. Collins showed them around, and, in talking with Jake, related how she missed home. Watters took this as a distraction and attempted to order Jake away from Collins. But Jake wouldn't stay away and he learned from Collins about Watters' addiction to cordafin stimulants.
After Watters ordered an attack of the Jem'Hadar battleship that failed, the bridge crew were eventually all killed except her. Nog convinced her to abandon ship with himself and Jake, and they were retrieved by the USS Defiant, where she was treated by Doctor Julian Bashir. She was the only Red Squad member to survive the destruction of the Valiant. In the end, she still believed Watters was a great man, though Nog said, despite that, he was a bad captain.

The short story "Dorian's Diary" in Strange New Worlds III establishes that Collins returned to Tycho City following the destruction of the Valiant, where she received counseling from Deanna Troi and a visit from Nilz Baris, the great-great grandfather of fellow Red Squad member Karen Farris. In 2374, she was awarded the Drakon Cluster of Courage. In 2375, she was assigned to the USS Wyandotte as part of a cadet assignment. Collins kept a diary of her life in which she documented her experiences during her recovery.
