Within the framework of this co-operation several Ph.D. students of the Chair of Biophysics (as Dr. Catasti at Davis, Dr. Gavazzo at Worchester, Dr. Carrara at Palo Alto, Dr. Vergani at Philadelphia, Dr. Adami and Dr. Sartore at Menlo Park and Murray Hill, Dr. Mariani at Utrecht, and Dr. Pechkova at ESRF) spent several months for a specialization stage. In turn, several foreign researchers coming from the above mentioned Institutes are attending now or have attended in the past years the Chair of Biophysics for short and long-lasting stages (more than 40 in these last years).
