In the early 2360s, Hickman served on the USS Victory as an ensign. In 2362, Hickman was part of an away team commanded by Susanna Leijten along with Geordi La Forge, Mendez, and Anthony Brevelle. They investigated the disappearance of a science team on Tarchannen III. While on the planet, the entire team was unknowingly infected with an alien DNA.
By 2367, Hickman had attained the rank of lieutenant.
In 2367, Hickman passed a routine physical on Malaya IV. Despite this, he was compelled to return to Tarchannen III by the changes in his DNA. Subsequently, he stole a shuttlecraft and was killed when his shuttle was destroyed in the atmosphere of Tarchannen III. (TNG: "Identity Crisis")
