Klein obtained his Ph.D. degree in neuropharmacology from the University of Colorado, Boulder, CO, USA. Klein is a specialist in gene transfer to the CNS and has been focusing on neuropathological proteins in Alzheimer’s and Parkinson’s diseases and amyotrophic lateral sclerosis: microtubule-associated protein tau, alpha-synuclein, and TDP-43. Klein’s educational background is in neuropharmacology during his Ph.D. at the University of Colorado and postdoctoral fellowship at the University of Florida, Gainesville, FL, USA. Klein has utilized the adeno-associated virus vector for both focal and global gene delivery to the CNS, for the purposes of creating relevant mammalian models of neurodegenerative disease and for preclinical gene therapy.
