In addition to his many discs, he has recorded a new series of CDs for the Stradivarius label, the most recent of which are dedicated to M. M. Ponce and J. S. Bach. In 2004, he received an honorary degree from the University of Hartford, Connecticut. Among the most illustrious students he would like to highlight M. Dylla, E. Fisk, S.-I. Fukuda, S. Grondona, L.
