She has advised clients in the United States and abroad in many sensitive and high-profile cases involving a wide range of legal and compliance matters, including allegations of securities and accounting fraud, insider trading, Foreign Corrupt Practices Act violations, money laundering, obstruction of justice, and unfair business practices. Ms. Katz frequently conducts corporate internal investigations, including investigations involving whistleblower complaints, retaliation claims, and violations of internal policies and procedures and criminal and civil regulatory laws. Ms. Katz is also a member of the firm’s Cybersecurity, Privacy and Data Protection Group and counsels clients on cybersecurity risks and incident response.

Ms. Katz was recently part of the trial team representing a director of a global investment firm in a high-profile monthlong insider trading jury trial in the Southern District of New York. Some of her other notable representations include defending the head of a multibillion-dollar investment fund indicted on Foreign Corrupt Practices Act violations, representing members of the audit committee of a large financial institution in an SEC investigation involving accounting irregularities, representing the chief executive officer of a broker-dealer in a FINRA arbitration, and defending financial services firms in investigations by the SEC and CFPB and in class action litigation.

Ms. Katz’s work on behalf of clients also includes litigating complex business matters in federal and state courts and in arbitrations, with particular emphasis on cost-effective discovery, fact development and trial work. She counsels and works with clients on developing company policies and employee training, and she has worked in collaboration with auditors and disclosure counsel. She regularly advises clients on data collection and discovery, including the use of predictive coding and technology-assisted review, and has successfully argued at discovery conferences in federal court. Ms. Katz also has extensive experience with international discovery matters involving a number of foreign jurisdictions, including Argentina, Brazil, the Cayman Islands, Italy, Luxembourg and Switzerland.

Ms. Katz is an active participant in the firm’s pro bono practice. In 2010, she was awarded The Legal Aid Society’s “Pro Bono Publico” Award for Outstanding Pro Bono Service.
