Tharp was a Bolian male serving in Starfleet in the late 24th century. By 2381, Tharp had attained the rank of lieutenant and served as a conn officer aboard the USS Aventine. Tharp was on duty at the conn when the Aventine answered a distress call from the USS Enterprise-E in the Azure Nebula during the Borg Invasion of 2381. After the two vessels began scouting subspace tunnels emanating from the nebula, Tharp was on duty when both ships traveled to near the Carina Arm and were engaged by Hirogen hunting vessels.
