Barry Slaughter Olsen

Associate Professor

Professor Olsen has been working as a conference interpreter and translator since 1993. Before joining our faculty, he was a translator in residence at American University in Washington, D.C. He has taught various courses on simultaneous and consecutive interpreting in the United States, Latin America and Europe. Over the years he has interpreted for the U.S. State Department, the Inter-American Development Bank, the Organization of American States, National Geographic Society, C-SPAN Television, and many other public and private sector clients. He is an active member of the International Association of Conference Interpreters (AIIC). In 2009, together with another the Institute alum, he founded InterpretAmerica--a forum dedicated to raising the profile of interpreting.

Recent Accomplishments

In 2014, Professor Olsen, together with fellow MIIS Professor Holly Mikkelson, published the English translation of From Paris to Nuremberg: The birth of conference interpreting (John Benjamins, Amsterdam, 2014). Originally written in Spanish by Jesús Baigorri-Jalón, the book is a seminal work on the genesis of conference interpreting and chronicles its development from the 1919 Paris Peace Conference to the end of the Nuremberg Trials after World War II.

Outside of class, he continues to work as a conference interpreter. His most recent assignments include the 2014 Ibero-American Presidential Summit in Veracruz, and the G20 Summit in Cabo San Lucas, Mexico, and the annual International Drug Enforcement Conference (IDEC).

Professor Olsen’s research over the last five years helped to create a patented cloud-based multi-channel audio conferencing system that makes remote simultaneous interpreting for teleconferences possible. The system is now used by organizations around the world to conduct virtual meetings in multiple languages with the help of remote simultaneous interpretation. He continues to research the use of technology to provide interpreting services in new ways.

In 2011, Professor Olsen was instrumental in the negotiation of a memorandum of understanding signed with the Organization of American States for the creation of a postgraduate conference interpreter and translator training experience for qualified Monterey Institute graduates.
