Porter was selected as a White House Fellow and served as Special Assistant to the President and Executive Secretary of the President's Economic Policy Board in the Ford White House. He joined the faculty at the John F. Kennedy School of Government at Harvard University in 1977. Porter returned to government service at the beginning of Ronald Reagan's administration, serving as executive secretary of the Cabinet Council on Economic Affairs and as director of White House Office of Policy Development. He rejoined the Harvard faculty in the fall of 1985 as the IBM Professor of Business and Government and faculty chair of the Senior Managers in Government Program. He returned to the White House at the beginning of George H. W. Bush's administration, where he served as Assistant to the President for Economic and Domestic Policy from 1989 to 1993. Porter has twice served as director of the Mossavar-Rahmani Center for Business and Government at Harvard. His teaching and research interests range widely. In 1987 he began teaching Harvard's course on "The American Presidency" pioneered by Richard Neustadt and later taught by Doris Kearns Goodwin; he has taught the course ever since except for the years when he was serving in the White House. He also teaches a large graduate course on "The Business-Government Relationship in the United States" as well as courses and modules on managing policy development, decision making, and economic policy. His books include Presidential Decision Making, The U.S.-U.S.S.R. Grain Agreement, and edited volumes on Efficiency, Equity, and Legitimacy: The Multilateral Trading System at the Millennium, and most recently, New Directions in Financial Services Regulation. He is a member of the President's Commission on White House Fellows, a member of the board of directors of the White House Historical Association, a trustee of the Gerald R. Ford Foundation, and a member of the advisory board of The Bush School of Government and Public Service at Texas A&M University.
