Born 1963.
Kathleen M. Hamm (born February 2, 1963) is an American lawyer, federal regulator and fintech and cybersecurity expert, formerly a board member of the Public Company Accounting Oversight Board, and Counselor to the Deputy Secretary of the U.S. Department of Treasury for cyber policy and financial regulation. In April 2021, her alma mater, University at Buffalo School of Management, named her Accountant of the Year.
Hamm was the global leader of securities and fintech services and senior strategic adviser on cyber solutions to the chief executive officer of Promontory Financial Group, a wholly owned subsidiary of IBM. She specializes in developing processes to embed regulatory requirements and cybersecurity into business operations and controls, changing how business systems are developed and improving their consumer protection. She also is a commentator on the opportunities and risks that emerging technology, such as artificial intelligence, presents to cybersecurity and ways that government and regulators may respond.
After leaving public service, Hamm established Pearl Advisory Group, LLC. She has served on the boards of several companies, including the Long-Term Stock Exchange, Inc., an exchange focusing on long-term value creation. She also is trustee and chair of the audit committee of the University of Buffalo Foundation, Inc., and chair of the Dean's Advisory Council for the University at Buffalo School of Management, SUNY.
Early life and education

Career
Hamm was appointed to the board of the PCAOB in January 2018 by the commissioners of the Securities and Exchange Commission, after consultation with the chair of the board of governors of the Federal Reserve System and the secretary of the Treasury. She earned a reputation for using the bully pulpit to increase auditors’ focus on cybersecurity, especially when conducting their risk assessments. She has continued to focus attention on cybersecurity at audit firms; and she has called for the combination of emerging technology and large-scale use of data to better arm investors and other financial statement users with consistent, comparable and decision-useful information on audit quality.
Hamm left the Board in November 2019 after completing her term. She joined the PCAOB from Promontory Financial Group, where she was the Global Leader of Securities and Fintech Services and Senior Strategic Adviser on Cyber Solutions to the chief executive officer, Eugene Ludwig, from February 2017 to January 2018. This was her second time working at Promontory, where she started out as a managing director, building the securities practice (October 2004 to September 2014). She was an early advocate for exchanges, hedge funds and global companies to improve their regulatory compliance and cybersecurity by embedding their legal requirements into their operations and control environments. In between the two positions at Promontory, Hamm served as Counselor to the Deputy Secretary of the U.S. Department of Treasury for cyber policy and financial regulation (September 2014 to January 2017). At Treasury, she also represented the United States on a cybersecurity expert group impaneled by the G7 finance ministers and central bank governors.
From 2001 to early 2004, Hamm served as the Senior Vice President in Charge of Regulation and Compliance for the Nasdaq-Liffe Markets(NQLX), which closed in December 2004. She worked briefly (2000 to 2001) at Wilson Sonsini Goodrich & Rosati, P.C., as a securities attorney; and at Streich, Lang, Weeks & Cardon, P.A. (1988 to 1990), as a corporate and securities associate.
She started her career at the SEC in the Division of Enforcement (1991 to 2000) as a Staff Attorney and Senior Counsel (1991 to 1995), then a Branch Chief (1995 to 1997), and an assistant director (1997 to 2000).
