Sebenius holds a Ph.D. from Harvard in business economics, a masters degree in Engineering-Economic Systems from Stanford's Engineering School, and an undergraduate degree (summa cum laude) from Vanderbilt in mathematics and English. In 1993, he took the lead in the School's decision--unique among major business schools--to make negotiation a required course in the MBA Program and to create a Negotiation Unit (department) which he headed for several years. Formerly on the faculty of Harvard's Kennedy School of Government, Sebenius also currently serves as Vice Chair and as a member of the Executive Committee of the Program on Negotiation (PON) at Harvard Law School. Sebenius left Harvard in the mid-1980s to work full-time for investment banker Peter G. Peterson, co-founder with Stephen Schwarzman of the New York-based Blackstone Group, now one of the world's leading merchant banking and private equity firms. For several years following Blackstone's launch, Sebenius worked closely with Peterson and Schwarzman, initially as vice president, and later as Special Adviser to the firm after returning to Harvard.
