School of Dental Medicine

Dr. MacNeil became dean of the University of Connecticut School of Dental Medicine in 2006. Dr. MacNeil is the 6th dean in the school's history, and was the first to be chosen from within the ranks of the dental school. Dr. MacNeil received a dental degree from Dalhousie University in Halifax, Nova Scotia, a certificate of advanced training in periodontics from the University of Connecticut School of Dental Medicine, and a Master of Dental Science degree from the UConn Graduate School. He has held academic positions at four dental schools; Dalhousie, Indiana University, the University of Michigan and the University of Connecticut. His research has led to more than 25 publications, primarily focused on cellular and molecular mechanisms regulating tooth development, periodontal wound healing and tissue regeneration. Dr. MacNeil is a consultant on curriculum to the Commission on Dental Accreditation and was a member of the Joint Commission on National Dental Examinations from 2001-2005 serving as chair of the commission in 2004-05. He joined the dental school in 1998 as an associate professor in the Department of Periodontology, attained the rank of professor in 2002 and has served as vice dean since 2005. Dr. MacNeil's career has not been limited to academics and administration. He was in full-time, private general dentistry practice for six years before pursuing advanced and graduate training at UConn, and his experience in private practice provide a strong understanding of the many professional challenges dental students face upon graduation and dental school alumni currently confront.
