At some point during his life, Boimler enlisted in Starfleet and attended Starfleet Academy where he received no demerits. He graduated and was commissioned as an officer in 2379. Upon graduating, he was assigned to the Cerritos. (LD: "Second Contact")
In 2380, during a stop at Douglas Station, Boimler was wounded when fellow Ensign Beckett Mariner, while intoxicated on Romulan whiskey, sliced his leg with a bat'leth. Later, while assisting in second contact efforts with the Galardonians, Captain Freeman asked Ensign Boimler to monitor Ensign Mariner's activities. Boimler eventually believed that he had caught her selling Federation weapons, but she had in fact been giving equipment to local Galardonian farmers. (LD: "Second Contact")
"First contact is a delicate, high-stakes operation of diplomacy. One must be ready for anything when Humanity is interacting with an alien race for the first time. But we don't do that. Our specialty is second contact. Still pretty important. We get all the paperwork signed, make sure we're spelling the name of the planet right, get to know all the good places to eat."
"You've been on what, four planets?"
"Five, if you include Vulcan."
"Of course I don't include stupid Vulcan! You may as well count Earth!"
"I was counting Earth..."
Brad Boimler was voiced by Jack Quaid.
