Dr. Hammer is the founder of several organizations that focus on intercultural competence development, conflict resolution, and critical incident management and crisis negotiation and resolution. He is also professor emeritus of International Peace and Conflict Resolution in the School of International Service at the American University in Washington D.C. His work spans a wide range of organizations including private corporations, not-for-profit organizations, state and local law enforcement agencies, and federal agencies, including NASA Johnson Space Center, The Federal Bureau of Investigation, and the National Institutes of Health. Dr. Hammer’s cutting edge work has resulted in (1) the Intercultural Development Inventory, an assessment instrument and process that is used throughout the world to build intercultural competence, (2) the Intercultural Conflict Style (ICS) Inventory, a theoretical model and assessment tool used by mediators, trainers, managers and counselors to bridge cultural differences in solving problems and resolving disagreements and conflict, and (3) the S.A.F.E. model of crisis negotiation used to de-escalate crisis situations (e.g., hostage, barricade, suicide) by federal and local law enforcement agencies as well as to manage social conflict in medical research testing controversial cancer therapies.
Dr. Hammer has served by appointment by the Director of the National Institutes of Medicine (NIH) as a Charter member of the Cancer Advisory Panel for the National Center for Complementary and Alternative Medicine. Dr. Hammer provided advisement on negotiation strategies concerning the hostage crisis in Peru to the Government of Japan as well as Japanese private-sector representatives who had employees taken hostage and has also advised negotiators involved in successfully securing the release of an American taken hostage in Latin America. Dr. Hammer has advised the Behavior and Performance Laboratory of the NASA Johnson Space Center for the International Space Station Program on cross-cultural communication. In 1996, Dr. Hammer, along with four associates, identified a set of letters with the writing of the so-called “Unabomber Manifesto” helping identify Ted Kaczynski as the “Unabomber.”
Dr. Hammer’s book, Saving Lives (2007) presents a comprehensive explanation of the innovative S.A.F.E. approach for resolving crisis situations. His previous book, Dynamic Processes of Crisis Negotiation: Theory, Research and Practice (1997), was honored with the “Outstanding Book Award” in 1998 by the International Association of Conflict Management. He has published widely, with over 70 articles, and has won numerous awards for his scholarship from various professional organizations, including the “Senior Interculturalist Award of Achievement” by the Society of Intercultural Education, Training and Research.
