Dr. Marcel Noujeim is an Associate Professor, Division of Oral and Maxillofacial Radiology (OMFR), Department of Comprehensive Dentistry. Dr. Noujeim received his dental degree and two specialty degrees in oral biology and maxillofacial radiology from the Lebanese University, School of Dentistry in Beirut. He began teaching dental radiology in September 1990 at the Lebanese University, School of Dentistry in Beirut and was appointed as division head from 1999 until 2002. In 2003, he moved to the United States where he finished a Master of Science (MS) degree in Dental Diagnostic Science (OMFR) from UTHSCSA Dental School in 2006. Dr. Noujeim became a Diplomat of the American Board of Oral and Maxillofacial Radiology in 2006. He was appointed to serve as the Oral and Maxillofacial Radiology graduate program director at UTHSCSA in 2008. Since he became program director, the pass rate of UTHSCSA oral and maxillofacial radiology residents challenging the American Board of Oral and Maxillofacial Radiology increased from 33% to 80%. He has 21 years of experience in teaching and practicing oral and maxillofacial radiology. He has given many presentations and continuing education courses at national and international meetings and has authored numerous articles and abstracts in national and international journals. Dr. Noujeim was the recipient of two awards given by the American Academy of Oral and Maxillofacial Radiology and the International Association of Dentomaxillofacial Radiology in 2005 recognizing him as being one of the best promising junior faculty/dental radiology educators. He has a US patent for an invention permitting the repositioning of CT data for comparison of minor bone changes. |
