Dr. Bellinger is a world expert on the role of the dorsomedial hypothalamic nucleus in regulating ingestive behavior and body weight. Most recently he has used his knowledge of feeding behavior to develop an NIH-funded animal model to study temporomandibular joint, myofacial and tooth nociception. These studies have led to a greater understanding of how gonadal hormones affect nociception.
Dr. Bellinger has been Principal Investigator or Co-investigator on 19 extramural NIH, NSF or company grants and many in-house grants. These projects have produced 149 peer-reviewed research publications and 204 abstracts. Dr. Bellinger’s publications have appeared in American Journal of Physiology; Archives in Oral Biology; Arthritis Rheumatism; Brain Research Review; European Journal of Pain; Hormone and Metabolic Research; International Journal of Oral and Maxillofacial Surgery; Journal of Cellular Physiology; Journal of Dental Research; Journal of Nutrition; Journal of Oral Maxillofacial Surgery; Life Science; Neuroendocrinology; Neuroscience; Osteoarthritis and Cartilage; Peptides; Pharmacology, Biochemistry and Behavior; Physiology and Behavior; Journal of Cellular Physiology; Journal of Neuroscience; Proceedings of the Society for Experimental Biology and Medicine and many other journals. Dr. Bellinger’s work has been well accepted and cited over 3,650 times with an h-index of 30 and a Research Gate Impact score of 445. He has been asked by 33 different journals, including Nature and Science, to review manuscripts and has reviewed NIH and NSF grants. He has been interviewed by Science magazine several times.
Dr. Bellinger has been asked to present his work numerous times, including several invited symposium talks in Japan, at the North American Association for the Study of Obesity, several Experimental Biology meetings, and the Society for the Study of Ingestive Behavior, as well as at various universities in the United States.
One of Dr. Bellinger’s former students, Carolyn Kerins, DDS, PhD, was awarded the first-ever NIH Individual Predoctoral Dental Scientist Fellowship in September 1998. This award of over $200,000 in direct/indirect costs funded Dr. Kerins' DDS and PhD program. She completed her DDS degree in 2002 and was awarded the PhD in May 2004; she is currently a tenured Associate Professor in the Department of Pediatric Dentistry, Texas A&M University College of Dentistry.
