Former Justice Department prosecutor Beth Wilkinson will examine Google's business practices as the FTC's year-old probe deepens. Wilkinson is best known for helping to convict Oklahoma City bomber Timothy McVeigh in 1997. She also has experience in antitrust law and white-collar criminal cases.
The move announced Thursday indicates the FTC probe may be moving into a new phase.
The FTC stressed that Wilkinson's hiring shouldn't be interpreted as a sign it intends to sue Google Inc.
European regulators are conducting a similar investigation into Google's tactics.
Google has consistently said it hasn't been doing anything wrong.
