Special Agent Timothy McGee, a.k.a. "Probie," is part of the NCIS team led by Special Agent Gibbs.

McGee gained his field agent status when he was transferred to Washington from Norfolk. In addition to responding to crime scenes and conducting investigations, McGee also serves as Gibbs' computer consultant.

Tim grew up in Bethesda, Md., and on the Naval Base in Alameda, Calif., as his father was a naval officer.

Before joining NCIS, he received a degree in Biomedical Engineering from Johns Hopkins University and a masters degree in Computer Forensics from MIT.

As the junior field agent of the team, McGee is often subject to ridicule from colleagues Tony DiNozzo and Ziva David, and, to some extent, even Gibbs.

McGee's many notable nicknames come from DiNozzo, either "Probie," due to his junior status on the team, or "McGeek," alluding to his intelligence.

DiNozzo uses multiple variations on his name make fun of McGee, some of which are clever and even complimentary (McGPS, McProof), others harmlessly mocking (McLawyer, McGiggle, McNerd).
