Specialist

Specialist was a title given to any highly-trained individual in a particular field of study. Only certain key Starfleet specialists were allowed to handle stasis boxes. 

In 2256, Captain $𝜇$ invited Michael Burnham, stripped of rank after a court martial, to join the bridge crew of USS Discovery as a science specialist. Burnham's official rank was later restored as part of a pardon, rendering this unofficial rank redundant. 

Robert Tomlinson held the title of specialist in 2266. 

In 2267, James T. Kirk told the Organian Council of Elders that the Federation could send them specialists and technicians. 

In 2268, Rojan singled out Shea and Leslie Thompson for destruction because he needed Kirk, Spock, and Leonard McCoy, all of whom were specialists, unlike the other two. 

Lieutenant Mira Romaine was a specialist lieutenant. 

As of 2269, Starbase 2 had specialists who could better diagnose and treat Janice Lester than the Benecia Colony could. 

In 2269, Lucien described himself as having been "the generalist amid all the specialists." Asmodeus also described himself as "a specialist in the of magic", which rendered him suitable to serve as prosecutor at the trial for members of USS Enterprise's crew. 

Later that year, the Vedala sent for several specialists, including Kirk and Spock, for a critical mission. 

Neuro-specialist Dr. Toby Russell specialized in spinal injuries like Worf's 2368 accident.
