Transnational Program on Criminal Justice

Fellows – Transnational Program on Criminal Justice

Two of the goals of TPCJ are supporting cutting-edge and important legal research by practitioners and scholars and to create bridges between legal practice and legal research in the United States and other countries. As a way to advance these goals, the TPCJ has welcomed practitioners and scholars at different stages in their careers from around the world. The list of our fellows have included:


Richard Dicker Richard Dicker

Richard Dicker has been director of Human Rights Watch's international justice program since it was founded in 2001, and has worked at Human Rights Watch since 1991. He started working on international justice issues in 1994, when Human Rights Watch made an effort to bring the government of Iraq before the International Court of Justice on charges of committing genocide against the Kurds. He later led a multi-year campaign to establish the International Criminal Court. In recent years he has worked to create more effective accountability mechanisms at the ICC. He monitored the trial of former Serbian President Slobodan Milosevic in The Hague and made many trips to Iraq before and at the start of Saddam Hussein's trial. A former civil rights attorney in New York, Dicker graduated from New York University Law School and received his LL.M. from Columbia University.
