Bradward "Brad" Boimler is a fictional character from the American science fiction television series Star Trek: Lower Decks. He is known for being ambitious while diligently following the rules of the service, and pleading excessively for his best friend, Ensign Beckett Mariner, an openly insubordinate ensign who regularly skirts the consequences, to do the same - although in the far future, Boimler is remembered for the Boimler Effect, a ship-wide mandate aboard the USS Cerritos encouraging breaking the rules, a distinction Boimler would not approve of.
