Ensign Brooks was a command division Starfleet officer aboard the USS Voyager, under Captain Kathryn Janeway . She was one of many crewmembers that survived the transport to the Delta Quadrant in 2371.
Brooks was among the crewmembers who were transported onto the Caretaker's array shortly after Voyager was lost in the Delta Quadrant. Alongside another officer, she scanned the region at captain's orders.
With a different hairstyle, Brooks was among the crewmembers who visited the market place on Sikaris and joined the inhabitants during the evening festival.
She was talking to a male crewmember in the mess hall when Neelix had a conversation with Captain Janeway.
Brooks was among the crewmembers who were left on Hanon IV after the Kazon Maje Culluh took over command of the Voyager.
In 2373, she greeted The Doctor while she passed sickbay. The Doctor, who was at the time malfunctioning, began to follow Brooks as she made her way to the turbolift. Unknown to her at the time, as Brooks traveled aboard the turbolift to Deck 10, The Doctor stood behind her plotting his move of malcontent against her. Fortunately, Brooks was saved when Tom Paris entered the turbolift and unknowingly interrupted The Doctor's plans.
In 2374, Brooks was one of the crewmembers given the task of examining cargo bay 2 to find out what had happened to Seven of Nine.
In 2378, Brooks attended the First Contact Day party in the mess hall and stood later in the hallway with much of the rest of the crew to bid farewell to Neelix when he left the ship for good.
