The team includes NCIS Special Agent Anthony DiNozzo (Michael Weatherly), an ex-homicide detective who may come off as the world's oldest frat boy, but whose instincts in the field are unparalleled; forensic specialist Abby Sciuto (Pauley Perrette), a talented scientist whose dark wit matches her Goth style and eclectic tastes, NCIS Special Agent Timothy McGee (Sean Murray), an MIT graduate whose brilliance with computers far overshadows his insecurities in the field and Ziva David (Cote de Pablo).
