The NIDA International Program supported three participants in a Regional Grant Writing and Scientific Peer Review Workshop that was held June 27–29, 2012, in Bogotá, Colombia. The workshop, which was organized by U.S. and Latin American officials, provided guidance on identifying training and funding opportunities, developing grant applications, establishing collaborations, and understanding the grant review process, confidentiality, and conflict of interest. Ivan Montoya, M.D., NIDA Division of Pharmacotherapies and Medical Consequences of Addiction, was one of the U.S. faculty members and made several presentations during the meeting. The NIDA-supported participants included 2001–2002 NIDA Hubert H. Humphrey Fellow Ines Bustamante, Ph.D., Peru; Franco Romani, M.D., Peru; and Maria Isabel Roldos, D.Ph., Ecuador.
