This Starfleet crewman served in the security division on board Enterprise since its launch in 2151.
He was working in engineering during the launch of Enterprise (ENT: "Broken Bow") and during the first contact with the Xyrillians. (ENT: "Unexpected")
He accompanied Lieutenant Reed's security team and sealed off Daniels' quarters. (ENT: "Cold Front")
In 2152, he assisted Lieutenant Reed and tried to stun a symbiotic lifeform which had boarded Enterprise. Unsuccessful, he went to the ship's Armory and helped Reed test a jerry rigged force field, telling Reed he was ready then repeatedly firing at the force field with a phase-pistol. He later assisted Reed with installing a set of EM emitters to emit a force field in a cargo bay, where the lifeform had settled down, and tried again to stun the lifeform. (ENT: "Vox Sola")
In January 2154, he was involved in a mutiny led by T'Pol. (ENT: "Hatchery")
