Ensign Barnes was an unjoined female Trill Starfleet operations division junior officer who lived during the 2380s. She served aboard the USS Cerritos under Captain Carol Freeman, and manned the operations station on the bridge. (LD: "Second Contact", "Strange Energies")
In 2380, during a second contact mission to the Galardon, Barnes went on a date with Ensign Sam Rutherford. They met in the officers' lounge and got to know each other over a drink, when a rage virus broke out on the ship. Barnes and Rutherford fought against the infected crew while still continuing to get to know each other. They became cut off from the crew, and embarked on a space walk to get to the rally point. They reached Deck 8 and took down more of the infected crew, but almost got trapped when a sealed door did not recognize their combadge signatures. With a quick adjustment, Rutherford got the door open, and both he and Barnes made it through before the door shut. Barnes immediately leaped into Rutherford's arms and kissed him passionately, but he seemed more concerned about the fact the doors did not open for them. He started ignoring her advance, and she walked away annoyed; they stopped dating each other afterwards. The two, nevertheless, made it to Transporter Room 8, where after she assisted in clearing a path through the "zombie" crew, as they made their way to sickbay. After the virus had been neutralized, she was at the ops station as the ship continued on to its next destination. (LD: "Second Contact")
She was again at ops during the mission to tow the alien ancient generation ship. During the same mission, she attended the management training session held in the officers' lounge. Back on the bridge, ordered Brad Boimler to report to bridge duty at 15:30. Boimler commented to himself, "Oh, I'll report to bridge duty, and they'll get exactly what they deserve!", however, she overheard the comment and asked "What?", to which he gave the quick cover story response of, "Uh– Oh, nothing! That was a holodeck. Uh, Moriarty." Shortly thereafter, she later reported that the USS Merced was moving close to the Cerritos' tow sector. (LD: "Moist Vessel")
She was on the bridge during the Cerritos' confrontation with the Drookmani ship over the salvage of the freighter NCC-502. She informed Freeman that the Drookmani had engaged their tractor beam and were attempting to load the cargo. She later attended the party to celebrate Fletcher's promotion to lieutenant. (LD: "Terminal Provocations")
In 2381, following Rutherford's minor personality change resulting from having his cybernetic implant ripped out, Barnes and Rutherford got back together. Barnes invited him to go swimming in Cetacean Ops, but this date was interrupted by D'Vana Tendi's attempt to rewrite Rutherford's neural pathways. (LD: "Strange Energies")
Later, while serving at ops during the Cerritos' cataloguing mission for the Collector's Guild, she reported to the captain that two escape pods had just launched from Kerner Hauze's ship. (LD: "Kayshon, His Eyes Open")
Later still, she was on the bridge when she notified Captain Freeman of an unknown ship approaching from the surface of Frylon IV, before she watched the events unfold during the scam that made it seem as if the Cerritos had accidently destroyed the ship with it's tractor beam. (LD: "Mugato, Gumato")
Some point later, she was on the bridge when the Cerritos received a transmission. After informing the Captain, she was ordered to put it onscreen which turned out to be Queen Paolana. (LD: "Where Pleasant Fountains Lie")
Later yet, she was stationed on the bridge when the ship received a message from the Bakersfield. After relaying the message to the captain, the ship then went to warp to assist the ship. Later that day, she participated in the training drills presented by Shari yn Yem, where she participated in the simulation, Whale Rescue, achieving a 73% score while the simulation was active. A holographic version of her appeared in the simulation The Naked Time where she was seen naked while kissing a holographic Jennifer Sh'reyan. (LD: "I, Excretus")
Rutherford described Barnes as being smart, pretty, and very effective in a ship-wide crisis, but did not share Rutherford's interest of running diagnostics on ship systems. She liked to play squash and was into music played by a classic rock band called The Monkees. (LD: "Second Contact")
Barnes' father was a cyborg. She had an older sister who was joined to a symbiont. According to Barnes, the joining completely changed her sister's personality as afterward she would not stop talking about having a symbiont. (LD: "Second Contact", "Strange Energies")
