My research focuses on the relationship between legal institutions and economic
organizations and development, particularly in comparative perspective. Much of my
scholarship is in the field of comparative corporate governance, but I have also written
about organized crime, financial regulation, the legal profession, foreign investment,
and the economic institutions used by authoritarian political regimes. I am particularly
interested in East Asia, and have written extensively on Japan, China, and Korea. A
recent focus is on "state capitalism" and role of state-owned enterprises in
the global economy. 

At Columbia Law School, I direct the Center for Japanese Legal Studies, which promotes
research and fosters intellectual exchange between the legal professions of the U.S. and
Japan. I am also the Director of the Parker School of Foreign and Comparative Law. In
that capacity, I direct the resources of the Parker School to promote faculty-level
research and collaboration with foreign institutions, particularly relating to developing
countries and non-Western legal systems, and to support teaching in the field of foreign

I teach courses on U.S. corporate law, the Japanese legal system, and seminars in the
field of law and development, comparative corporate law, and the role of the corporation
in global affairs. I present research and teach frequently outside the United States. In
2012 and 2010, I was named Teacher of the Year at the Duisenberg School of Finance of the
University of Amsterdam, where I regularly serve as Visiting Professor.
