Right from CARIM's inception, its management has recognized the im portance of promoting cooperation with institutes abroad. This policy has led to close contacts between CARIM and many other institutes in Europe and the United States. CARIM has formalized its international collaboration with the Institut Féderative de Recherche Cardiovasculaire Lariboisière in Paris. An agreement for collaboration was signed in 2001 with the University of Edinburgh. This agreement strengthens a long-term existing collaboration with the Center for Transgene Research of this Uni versity. CARIM participates in seve ral Wellcome Trust funded British genomic research consortia. As much as the financial means allow, staff members and researchers are regularly posted abroad to learn new techniques and gain new experience, which can then be implemented in CARIM's research program after their return to Maastricht.
At their own or CARIM's request, visiting researchers from foreign institutes come to Maastricht for extended working visits, and each year various researchers come to spend their sabbaticals at our institute. The cooperation often leads to joint publications, and if the contacts are very close there may even be staff exchanges in the form of, for instance, 'affiliate professorships'. At present the following affiliate professors have been appointed:
. Prof. J.B. Bassingthwaighte, University of Washington, Center for Bio engineering;
. Prof. Y. Nemerson, Mount Sinaï School of Medicine, New York;
. Prof. A.J. Schroit, Anderson Cancer Center, Houston;
. Prof. A. Bonen, University of Waterloo, Department of Kinesiology, Waterloo, Ontario, Canada.
. Prof. P. Carmeliet, University of Leuven, Belgium.
. Prof. M. Safar, University of Paris, France.

Foreign scientists, mostly post doctoral fellows visiting CARIM for research training, as well as visiting scientists of collaborating institutes, participated in the CARIM activities in 2004. top
