Dr. Lisa Cuddy’s surname is Cuddy in House M.D.
Cuddy is the Dean of Medicine and hospital administrator at Princeton-Plainsboro Teaching Hospital. She supervises House, manages institutional responsibilities, and frequently tries to balance his diagnostic brilliance against his disregard for rules, budgets, and workplace procedures.
Lisa Edelstein played Cuddy throughout the show’s first seven seasons. Cuddy and House have a complicated professional and personal relationship, which becomes an important part of the series’ later story. Her authority over House creates recurring conflicts, but she also recognizes the value of his medical ability.
The distractors are names of other female doctors associated with the series. Cameron is a member of House’s original diagnostic team, Thirteen is Remy Hadley’s nickname, and Masters is Martha M. Masters. Cuddy is therefore the hospital leader’s surname, not the name of a diagnostic-team member.
