Ephron Rosenzweig earned his BA in Integrative Biology from UC Berkeley and his PhD in Neuroscience from University of University of Arizona, Tucson, followed by postdoctoral posts at Washington University in St. Louis and UC San Diego, where he became an assistant project scientist in 2008.

He has extensive experience in CNS plasticity and regeneration research, in both rodent and primate models of spinal cord injury. In addition, he has many years of experience in electrophysiological research on learning, memory, and aging. Since 2005, he has directed the Primate Spinal Cord Injury Research Project at Dr. Mark Tuszynski’s Center for Neural Repair at UCSD. This collaborative effort is a comprehensive evaluation of potential treatments for spinal cord injury.

Dr. Rosenzweig primarily researches spinal cord injury repair. Much of his work is part of the California Primate Spinal Cord Injury Consortium, a group composed of researchers from UCSD, UCLA, UCSF, UC Irvine, UC Davis, Colorado State University, and the Swiss Federal Institute of Technology.

Drawing only the most promising candidate treatments from research in rodent models of SCI, this group examines the neuroanatomical, electrophysiological, and functional efficacies of those treatments in a non-human primate (NHP) model of SCI. His main current focus is on the formation of long-distance neuronal relays using neural stem cells transplanted into SCI lesions. As part of the UCSD Center for Neural Repair, he also collaborates on similar studies in rodents (Lu et al., Cell, 2012).

Recently, Dr. Rosenzweig expanded his research program to include central neuropathic pain, which not only affects many people with SCI, but can also result from multiple sclerosis and stroke. He is attempting to use DREADD technology (Designer Receptors Exclusively Activated by Designer Drugs) to specifically alleviate central neuropathic pain in rodent models.
