Forensic team
From Memory Alpha, the free Star Trek reference.
The forensic team is a special group of crewmembers of a starship that are specially trained to search for miniscule evidence.
Several forensic teams of the USS Enterprise-D were ordered in 2367 to search for any evidence in cargo bay 4 in the form of DNA samples or biochemical signatures for who transported weapons down to Krios.
Ensign Kellogg was part of one of the forensic teams. (TNG: "The Mind's Eye")
