Before joining the Firm, Ms. Ratner served in the Office of the Solicitor General at the U.S. Department of Justice. During her tenure there, she argued Supreme Court cases involving areas of federal law such as securities regulation, bankruptcy, employment, intellectual property, criminal law, and elections law.
