A child genius, Roman had multiple degrees by age seventeen when he decided to sign up with NASA.
He was the youngest member of the Bowie Base mission, noted for an instinctive talent for mechanics. While escaping from Bowie Base One, he was infected by the Flood when a single drop of water fell on his cheek. He warned Adelaide Brooke and the remaining members to run before he transformed. He was killed when Adelaide blew up the entire base. (TV: The Waters of Mars)
