Biography
George Bittner graduated from Duke University in 1962 where he received his AB in Chemistry, Magna Cum Laude. He entered Stanford University as an MD/Ph.D. student in 1962. He withdrew in good standing (6th in Class) from Stanford Medical School in 1966 to devote full time to research under the tutelage of Dr. Donald Kennedy (Chairman of Biological Sciences). He received his Ph.D. in Neuroscience in 1967 from Stanford University. He began his postdoctoral work in the Department of Anatomy and the Brain Research Institute at UCLA with Dr. Jose Segundo and joined the faculty at the University of Texas in 1969. Dr. Bittner has had extensive collaborations with scientists in the US. He has been a Visiting Professor at Case Western Reserve University in Cleveland and a visiting scholar at the University of Western Australia (Nedlands,Perth). He has served on many NIH and NSF panels and was Chairperson of the Neuroscience Panel for Howard Hughes and NSF Predoctoral Fellowships in1996. his research is widely known both nationally and internationally, as recognized in part by a Research Career Development Award from the National Institutes of Health, his election as a fellow of the American Association for the Advancement of Science (AAAS) in 1992. Dr. Bittner was one of four founding members of the Institute for Neuroscience at the University of Texas and served for over a decade on its Executive Committee. He is a Professor of Neuroscience at the University of Texas at Austin and an adjunct Professor at the Department of Physiology/Biophysics at the University of Texas Medical Branch (UTMB) at Galveston, TX.
Research
We research cellular/molecular mechanisms of plasmalemmal repair and nerve regeneration. That is, we examine various biophysical, biochemical, or molecular mechanisms by which lesioned neurons repair lesions to their plasmalemma and regenerate axons. We are particularly interested in the role of calcium and axonal proteins in plasmalemmal repair and how such plasmlemmal repair relates to axonal regeneration. we are also interested in how polyethylene glycol (PEG) can be used to repair severed axons so that axonal continuity and function can be permanently repaired within minutes after applying PEG to rejoin severed axons. We also explore and define biochemical pathways by which neurons repair plasmalemmal damage.
