Visiting Scientists and Scientist Envoys

CAI2R offers visiting scientists the multidisciplinary experience essential for effective development and translation of new technologies.

We also dispatch scientist envoys to train peers at faraway institutions.

Hands-on Experience in Translational Research

The visiting scientists program embeds participants in our unique translational research teams. Visitors join interdisciplinary groups of experts engaged in project- and patient-focused technical development.

Successful translational research teams combine breadth and depth of expertise with rich and frequent communication. This collaboration model leads to faster prototype iteration, shorter development cycles, and greater positive impacts on clinical practice and patient care.

Science without Borders

Our investigators periodically travel to distant collaboration sites for extended research and educational visits.

During these trips, our researchers act as scientist envoys—they share the latest imaging advances, train colleagues in implementation of technologies developed at our Center, and educate peers on the model of multidisciplinary translational teamwork that underpins CAI2R.

Scientist envoys have been dispatched to Austria, Brazil, Belgium, Germany, Italy, Japan, and Switzerland.
