He was a full-time faculty member at UNC School of Dentistry from 1992 until 2004, first as an assistant professor and then associate professor with tenure beginning in 2000.  He was appointed as the graduate program director of endodontics (specialty training) in 1997 and served in that position until 2004. From 2004 to 2012 he was in a private endodontic practice in Reykjavik, Iceland, and London, England. In September 2012 he became the chairman of the department of endodontics at New York University College of Dentistry. Additionally, he holds the following academic positions: From 2004 adjunct associate professor at UNC; honorary clinical teacher in endodontology, UCL Eastman Dental Institute, London, from 2006; and from 2011 honorary clinical associate professor in the Faculty of Dentistry, the University of Hong Kong. He has lectured extensively around the world on dental trauma, endodontics, pain diagnosis and forensic dentistry. He is active in many professional organizations and is past president of the International Association for Dental Traumatology (IADT). He received the Edward M. Osetek Educator Award from the American Association of Endodontists in 1998.
