International Program Contributors

The enhanced international component of the Colloquium is due in large part to the efforts of Drs. Maria Oquendo and Bernardo Ng. International participants are sponsored by their institution, country’s psychiatric association, country's branch of the Society of Biological Psychiatry (SOBP) or are self-funded.
