St. Bonaventure University

Faculty Emeriti

Professors from all schools in the university who have been bestowed the title of "emeritus" upon retirement from full-time teaching.

The title of professor emeritus is an honorary designation that may be awarded to recognize those who have retired with the earned rank of associate professor or professor after at least 10 years of full-time meritorious service to the university and their field of knowledge. While no longer full-time faculty members, some continue to teach on occasion as adjunct instructors.
