In that year he also took on the directorship of the Institute for Law and Economics. Under his leadership, ILE has grown to become a nationally recognized center at the intersection of law and business which brings together at roundtables and conferences eminent law and finance scholars, judges, lawyers, private equity and hedge fund managers, and general counsels of major public corporations to discuss cutting edge issues in corporate governance and corporate finance.


Wachter served as Deputy Provost of the University of Pennsylvania from July 1995 to January 1998, and as Interim Provost from January to December 1998. His current research focuses on corporate governance and topics in the intersection of corporate law and finance.
