Who Am I?

I am a former federal prosecutor with extensive trial experience in the United States, including election to the prestigious American College of Trial Lawyers.  Since 1980, I have been a litigation partner in top US law firms, most recently Debevoise & Plimpton, LLP. You can see more about me in my Curriculum Vitae.

In 2006 I moved to France where I sat for the Paris Bar and practiced French law for almost 12 years.   This included participating in criminal trials in French courts (leading to the acquittal of a major international corporation of criminal charges), and extensive experience handling multi-jurisdictional investigations applying both civil law and common law criminal justice norms.   I also served as adviser to the Prosecutors at the International Criminal Court and the International Criminal Tribunal for Rwanda.  For my work representing French interests, the French government named me a “Chevalier” of the National Order of Merit of France. 

Since 2016 I have combined my practice with teaching academic courses on comparative criminal justice and cross-border criminal investigations, first at the University of Amsterdam and now at Columbia Law School, where I am a Lecturer in Law, as well as at the Ecole Nationale de la Magistrature in France.  I have published widely in English and in French in the area of transnational criminal practice, and in 2019 Cambridge University Press published my book American Criminal Justice: An Introduction, of which foreign language versions are in preparation.  My principal bibliography is listed under Publications in this site.
