A Starfleet lieutenant serving as aide to Admiral Dougherty in Star Trek: Insurrection, who is among the observers held in the Ba'ku village after Data exposes the hidden survey.
Lieutenant Curtis is attaché to Vice Admiral Matthew Dougherty during the joint Federation and Son'a study of the Ba'ku in 2375, shown in Star Trek: Insurrection.
He is part of the team secretly watching the village from a cloaked hide when Data, damaged and acting on his ethical subroutines, reveals the observers to the Ba'ku. The Starfleet and Son'a personnel are rounded up and kept in the village as guests rather than prisoners.
When Picard beams down expecting a hostage rescue, Curtis introduces himself and reports that everyone has been well treated; the Ba'ku had simply been waiting for someone to come and collect them. The scene gives Picard his first look at the people Dougherty plans to move.
