The Georgia School of Orthodontics Institute for Orthodontic and Dentofacial Orthopedic Research utilizes GSO’s cutting-edge research to improve our patients’ clinical treatment and experience. Our aim is to initiate well designed clinical research to position GSO as a pioneer in the field of orthodontic research. The key to our effort is providing the required infrastructure, research funding, and personnel to achieve our goals of being preeminent both nationally and internationally in the next five years. The funding dedicated to the Institute aids research in trials on accelerated orthodontics, three-dimensional cone beam computed tomography, and Clear Aligners.

Research at GSO gives an excellent opportunity for the graduate residents to investigate and have firsthand experience in this scholarly activity. The residents work closely with a primary investigator who guides them through conducting the research, which helps to develop critical thinking and improve their communication skills. Additionally, the school also encourages the residents to present their research findings at American Association of Dental Research and American Association of Orthodontics meetings held annually.

Research Directors

Our innovative research department is led by our Director of Research, Dr. Nandakumar Janakiraman, and our Assistant Director of Research, Dr. John Stockstill. Their extensive experience and publications ensure that GSO stays at the forefront of orthodontic study.

Dr. Janakiraman obtained his dental degree from Government Dental College Bangalore University, India in 1998, and a master’s degree in orthodontics from Government Dental College NTR University of Health, India in 2002. He moved to the United States of America in 2010 after getting accepted to the Fellowship Program in Orthodontics at the University of Connecticut. In the next three years, he obtained his master’s degree (M.Dent.Sc) and a certificate in orthodontics. He served as full-time faculty member at University of Connecticut from July 2014 – May 2016. Later he joined the faculty of the University of Louisville as Assistant Professor and Research Director.

Dr. Janakiraman is a Diplomate of American Board of Orthodontics and member of AAO and SAO. He has published twenty articles in peer-reviewed orthodontic journals and contributed to two chapters in orthodontic textbooks. Additionally, he has presented his work in scientific meetings both nationally and internationally. His research interests have primarily focused on reducing treatment time and improving the evidence and biomechanical knowledge of various orthodontic techniques and appliances. His publications have covered numerous topics including investigating new orthodontic techniques and appliances, re-evaluating routinely used orthodontic systems in order to throw greater light on them, and more recently, integrating the current 3D technologies into clinical orthodontics. One of his primary objectives as a researcher and clinician is to translate his research findings to more efficient and effective outcomes for patients.

Dr. Stockstill attended the University of Louisiana-Lafayette and received a Bachelor of Science (’73) in Pre-Dentistry. After completing his Doctorate in Dental Surgery (’75) from Louisiana State University Health Science Center School of Dentistry he served for two years in the U.S. Public Health Service/U.S. Coast Guard as a staff dentist (rank of Lieutenant) and received an honorable discharge in 1977.

Dr. Stockstill attended the State University of New York at Buffalo School of Dental Medicine as a Neuromuscular Research in Clinical Dentistry Fellow and completed his M.S. in Oral Sciences and Certificate in Temporomandibular Disorders/Orofacial Pain in 1987. He served as Assistant Professor at the University of Nebraska Medical Center College of Dentistry and was promoted to Associate professor in 1994. He entered the Orthodontic Residency at the UNMC College of Dentistry and received his Certificate in Orthodontics in 1996. Later he joined the faculty at Creighton University School of Dentistry where he served as Associate professor until 2001, when he joined the Medical College of Georgia College of Dental Medicine as Director of Orthodontic Research and Director of undergraduate orthodontic curriculum.

In 2012 he joined the faculty of the ECU School of Dental Medicine as Division Director of Orthodontics and as Director of Curricula in Orthodontics as well as TMD/Orofacial Pain. After successfully developing the orthodontic and TMD/Orofacial Pain curricula at ECU, Dr. Stockstill was recruited by Seton Hill University to serve as Professor of Orthodontics within the Center for Orthodontics residency program. He now serves as Professor and Assistant Director of Research at the Georgia School of Orthodontics.
