Dr. O’Connor comes to Palm Beach Atlantic after serving as a visiting and adjunct faculty member at the University of Delaware and the University of Maryland-College Park. Dr. O'Connor has enjoyed a varied musical career, which has included time as a high school band director, a professional performing musician, and a church music director. Dr. O'Connor's research has explored the intersections of musical composition and historical theology in medieval and Renaissance Spain. His dissertation addressed the subject of Juan de Esquivel's (c. 1560–c. 1626) compositions on texts devoted to the Virgin Mary. The dissertation was not only the first doctoral level work to explore the biography and music of that important Spanish musician, but it also traced new paths in a wider examination of how Spanish composers approached certain sacred genres in similar ways. His secondary interests include American concert music, historic brass instruments and their music, and 19th-century American popular music. Dr. O'Connor has presented his research to conferences in the U.S., Belgium, Portugal, and England, and his publications have appeared in the New Grove Dictionary of Music and Musicians, Second Edition; The Alamire Foundation Proceedings, and Medieval Perspectives. His history of the euphonium appears as the first chapter in Guide to the Euphonium Repertoire: The Euphonium Source Book, recently published by Indiana University Press. He served as editor of the Historic Brass Society Newsletter and currently edits news and information for the HBS Web site. Concurrent with his teaching and research, Dr. O’Connor has remained an active performing musician. He was the founding member of the Renaissance brass group, the Washington Cornett & Sackbutt Ensemble, and created a period-instrument late 19th-century band called Newberry’s Victorian Cornet Band. He is also a member of the Federal City Brass Band, which recreates a Civil War regimental band. This interest in historical performance has translated to the university environment through his positions as director of the early music ensembles at the University of Delaware and the University of Maryland-College Park.
