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. 

I direct the Center for Japanese Legal Studies at Columbia Law School, which promotes
research and fosters intellectual exchange between the legal professions of the U.S. and
Japan. 

I formerly served as the Vice Dean for Intellectual Life at the Law School. In addition
to organizing various in-house workshop series, my principal responsibility was to expand
international faculty-level research and collaboration, particularly relating to
developing countries and non-Western legal systems. 

I lecture and teach frequently around the world. At Columbia, I teach courses on U.S.
corporate law, the Japanese legal system, and a variety of seminars in the field of law
and development, comparative corporate law, and the corporation in global context. In
2010, I was named Teacher of the Year at the Duisenberg School of Finance of the
University of Amsterdam, where I also teach regularly.
