David Kohn - December 2013

0 2664

David Kohn, Ph.D., is a professor at the University of Michigan, Ann Arbor, USA, with appointments in the School of Dentistry and College of Engineering. He received his B.S. in biomedical engineering from Tulane University, New Orleans, Louisiana, (1983) and his Ph.D. in bioengineering from the University of Pennsylvania, USA (1989).

He joined the faculty at the University of Michigan in 1989 and has progressed through the academic ranks. He is director of an NIDCR training program in tissue engineering. In 2000-2001, Kohn was a visiting professor in the Craniofacial and Skeletal Diseases Branch of the NIH.

Jane Shin - November 2013

0 3011

In May 2013, AADR member Jane Shin began her 2013 student fellowship in the HHMI Medical Research Fellows Program. Shin is a D.M.D. student at the Harvard School of Dental Medicine. Shin was one of 66 students selected from more than 200 applicants. Shin is taking leave from the D.M.D. program to devote a year to her HHMI Medical Research Fellows Program research project titled “The Role of Appetite Hormone Ghrelin in Type 2 Diabetes-Associated Periodontitis.” Her project mentor is AADR member Toshihisa Kawai, at the Forsyth Institute.

Shin’s study is based on the hypothesis that Ghrelin produced in periodontal tissue plays a regulatory role on bone resorption caused by T cell-derived RANKL in the context of periodontal disease, and diminished Ghrelin in the type-2 diabetes (T2D) condition can be a risk factor for periodontal disease. She will work on examining the possible regulatory role of Ghrelin on soluble RANKL (sRANKL) production by activated T cells in in vitro experiments, and explore Ghrelin in an in vivo mouse model of type 2 diabetes-associated periodontal disease.

Roger Johnson - October 2013

0 2823

Roger Johnson, D.D.S., Ph.D., is professor, periodontics and preventive sciences, at the University of Mississippi Medical Center, Jackson. He has previously served on the faculty of the University of Manitoba Faculty of Dentistry, Winnipeg, Manitoba.

Johnson earned his Ph.D. from the University of North Dakota and his D.D.S. from the University of Tennessee. His research interests are mechanisms in the etiology of periodontal disease, systemic effects of oral (endodontic) inflammation and the use of saliva as a diagnostic fluid. His clinical interests are periodontal diseases and osteoporosis.


Janet Guthmiller - September 2013

0 2848
Janet Guthmiller, D.D.S., Ph.D., is associate dean for academic affairs and professor in the Department of Periodontology at the University of North Carolina – Chapel Hill School of Dentistry. Currently, she is leading the dental school in a comprehensive review and revitalization of the D.D.S. curriculum. Previously, she was full-time faculty at the University of Maryland and the University of Iowa where she was involved with predoctoral and postdoctoral education, maintained a private practice and performed research.
Guthmiller received her D.D.S. from the University of Iowa College of Dentistry, and her Periodontal Certificate and Ph.D. in cellular and structural biology from the University of Texas Health Science Center at San Antonio as a part of the NIH-sponsored Dentist-Scientist Program. Guthmiller’s NIDCR funded research has encompassed molecular biological studies of periodontal pathogens and expression and function of innate antimicrobials. She has published numerous manuscripts and abstracts. 

Mark Mooney - August 2013

0 2696

Mark Mooney, M.S., Ph.D., is professor and chair of the Department of Oral Biology and holds joint appointments in the Departments of, Anthropology, Plastic and Reconstructive Surgery, Orthodontics, and Communication and Speech Disorders in the Schools of Dental Medicine and Medicine at the University of Pittsburgh, Pennsylvania. He received his M.S. in biological psychology at Western Illinois University in Macomb, Illinois, and his Ph.D. in physical anthropology at the University of Pittsburgh.

His research interests have included craniofacial and developmental biology, and the complex genetic and environmental factors that are involved in shaping the human face and body. His principal interest has been the development of various animal models to investigate the interaction of surgery and congenital facial abnormalities on postnatal craniofacial growth in individuals with birth defects to the head and neck.
