Professor C. Sue Carter is currently Director of the Kinsey Institute and Rudy, Professor of Biology at Indiana University, a position she accepted in 2014. Prior to her current position she held Professorships at the University of Illinois, Champaign-Urbana and the University of Illinois at Chicago, Department of Psychiatry, as well as the University of Maryland and the University of North Carolina. Dr. Carter is a neurobiologist, known for her research on the biology of social bonding and the development of the prairie vole as a model for studying the behavioral and physiological actions of peptide hormones. Research originated by Dr. Carter has shown that oxytocin is at the biological heart of positive emotions, including love. Oxytocin and its receptors can facilitate a sense of safety, which in turn allows social cognition, social bonding, social support, growth and restoration. The oxytocin system also plays a major role in early life and is epigenetically influenced by experience. The capacity of oxytocin to regulate the brain and behavior across the lifespan helps to explain the adaptive consequences of social bonds and attachments for emotional and physical health, especially in the face of fear and anxiety

Recognized for integrating dynamics of hormone processing and axonal transport in neurosecretory cells.

show more


Dr. Harold (Hal) Gainer obtained his B.S. in Chemistry from the City College of New York, and his Ph.D. in Physiology and Biochemistry from the University of California, Berkeley. After a brief period as a Postdoctoral Fellow at Berkeley and as an Instructor in Physiology at UCSF, Dr. Gainer did further postdoctoral work on the electrophysiology of muscle and synapses at Columbia University College of Physicians and Surgeons in New York in the laboratory of Harry Grundfest. Dr. Gainer moved to a faculty position at the University of Maryland where his research focused on mechanisms of sound production in marine animals and on the role of calcium in excitation-contraction coupling. He was an adjunct/visiting professor at the University of Maryland, George Washington University and Tel-Aviv University, Israel, and a summer investigator at the Marine Biological Laboratory, Woods Hole. In 1969, Dr. Gainer joined the NIH, National Institute of Neurological Diseases and Stroke (NICHD) as a Research Physiologist, and later became Chief of the Laboratory of Neurochemistry and Immunology in NICHD. In 1987 he moved to the NINDS to become Chief of the Laboratory of Neurochemistry, and also served as Basic Neuroscience Director from 1990-2000, and as Acting Scientific Director from 1994-1995 in the intramural NINDS, NIH. Dr. Gainer’s laboratory studied the cell and molecular biology of oxytocin and vasopressin peptidergic neurons in the mammalian hypothalamus. Dr. Gainer retired in 2012, and is presently a Scientist Emeritus in NINDS, NIH. Dr. Gainer’s research expertise is in the mechanisms that are involved in the establishment and maintenance of specific peptidergic neuronal phenotypes in the central nervous system. He studied the cell biological and molecular processes that underlie cell-specific expression of oxytocin and vasopressin genes, and the biosynthesis, sorting, packaging and neurosecretion of the resulting neuropeptides in the hypothalamus. In order to examine these issues he focused on two neural systems in the CNS: 1) the magnocellular neurons of the mammalian hypothalamo- neurohypophysial system, which secrete the nonapeptides, oxytocin and vasopressin into the general circulation, and 2) and neurons in the suprachiasmatic nucleus which secrete vasopressin in a circadian fashion into specific hypothalamic sites.

Tomas Hökfelt

Recognized for revealing the extent and meaning of neuropeptide and aminergic co- transmission in neurons and neuronendocrine cells in mammalian brain.

show more


Tomas Hökfelt is a professor in the Department of Neuroscience at the Karolinska Institute, Stockholm, Sweden. Professor Hökfelt is one the fathers of the field of neuropeptide research. His research focuses on the localization and function of neuropeptides in the healthy and diseased brain. Dr. Tomas Hokfelt describes his laboratory’s research as ‘focused on chemical messengers in the nervous and endocrine systems, mainly based on histochemical techniques’. This low-key description captures a lifetime of regulatory peptide research that includes driving the entire neuropeptide field by exhaustive demonstration of peptide/classical transmitter co-existence, the implications of which are still being worked out; physiological functions of distinct neuropeptides in autotony, pain, stress, cognition and other physiological functions; and localization of neuropeptides to established and novel brain and endocrine circuits leading to uncovering of their functions. Dr. Hokfelt has received much recognition and many honors for his research: these include induction into the National Academy of Sciences USA at the age of 44; doctorates honoris causa at universities throughout the world; the Erasmus Medal (in 2011); and many others. Transcending all of these accolades is the recognition of his scientific peers that, in identifying neuropeptides as the molecular engineers of adaptation to paraphysiological stressors, Dr. Hokfelt defined the potential and the mission of the regulatory peptide field decades ago, and for decades to come. The IRPS is honored to include Dr. Hokfelt as a Distinguished Member.
