O'Neal has served as president and COO at Merrill Lynch for the past year, overseeing the global operations of the corporation's chief business interests: global markets and investment banking, private clients, and investment management.
He will become chief executive officer of Merrill Lynch in December, and chairman of the board of the company in April 2003.
Until July 2001, O'Neal was president of the U.S. Private Client Group, one of Merrill Lynch's four core business groups. Previously, he served as executive vice president and chief financial officer of Merrill Lynch, where he worked closely with executive management to maximize the strategic use of the company's financial assets.
"We are privileged to have Stan O'Neal join the CSIS board of trustees," said former Senator Sam Nunn, chairman of the CSIS board. "He brings vast experience in international business and finance, which are critical components of our international relations. CSIS will benefit enormously from the strategic perspective Stan O'Neal provides."
