Ahead of its first hearing this week, the Financial Crisis Inquiry Commission named Thomas Greene its executive director Monday.
Greene moves to the commission, which is charged with investigating the cause of the financial crisis, after 25 years in the California Attorney General's Office.
He was most recently the chief assistant attorney general of the public rights division and has worked on the antitrust case against Microsoft Corp.
"Tom has the skills and experience needed to help the commission conduct the full, fair inquiry into the financial meltdown that the American people deserve," Phil Angelides, the commission's chairman, said in a press release.
Angelides, who is a former California state treasurer, will convene the commission's first hearing Thursday. The panel is required to report its findings in December 2010.
