Professor of Neurosurgery and Neurology
Kinetics Foundation Chair in Translational Research

Krystof Bankiewicz received his MD degree from Jagiellonian University in Crakow, his PhD and DSc degrees from the Institute of Neurology and Psychiatry in Warsaw, and the title of Professor from the President of the Republic of Poland. After his residency and an appointment as Assistant Professor with the Post-graduate Medical Center in Warsaw, he received a Fogarty Fellowship and became a Visiting Fellow and then Visiting Associate Scientist with the Surgical Neurology Branch of the NINDS at the NIH in Bethesda, Maryland. There, he became Chief of the Central Nervous System (CNS) Implantation Unit in 1991. Shortly afterward, he came to California to serve successively as Chief of Preclinical Studies with the Somatix Therapy Corporation in Alameda, the Director of the Division of CNS Implantation and Regeneration with The Parkinson's Institute in Sunnyvale, and from 1994-1998 a Visiting Scientist with the Laboratory for Functional Imaging of the Lawrence Berkeley National Laboratory. From 1997-2001 he returned to the NIH as Acting Chief of the Molecular Therapeutics Section of NINDS. Since 1998 he has been a Professor in Residence of Neurosurgery and Neurology, Principal Investigator with the Movement Disorders Research Program and the Brain Tumor Research Center at the University of California San Francisco (UCSF). In 2009 Prof Bankiewicz was named the recipient of Kinetics Foundation Chair in Translational Research and in 2011 was appointed as a Vice Chairman for Research in Department of Neurological Surgery and Director of Translational NeuroTherapy Center at UCSF. Dr. Bankiewicz is an inventor of numerous patents, and has published more than 160 peer-reviewed research articles. Dr. Bankiewicz has considerable experience in supervising multi-investigator translational programs. He is a Principal Investigator on several multi-center, multi-investigator grants. He has supervised a total of 25 post-doctoral fellows, and manages a core research group of 20 individuals including technicians, post-doctoral fellows, and a senior scientists. Throughout his career, he has maintained a strong focus on the development of translational approaches to gene and cell replacement therapies, and has displayed a remarkable ability to synthesize several individual technologies into powerful new approaches to the treatment of such serious diseases as brain cancer and neurodegenerative disorders of the brain, including Parkinson's, Huntington’s, Alzheimer’s diseases and pediatric neurotransmitter deficiency and lysosomal storage disorders. Dr. Bankiewicz was instrumental at every stage of the Phase-1 clinical trials for AAV2-hAADC and AAV2-hGDNF gene therapy, resolving technical and scientific issues with respect to filing an IND applications with the FDA, and also in recruiting a clinical team to undertake the clinical trials. He continues to champion the development of novel therapeutic strategies to treat these important diseases. The recently established Translational NeuroTherapy Center at UCSF, of which he is the first Director, is a logical extension of Dr. Bankiewicz’s efforts to close the gap between bench and bed side by engaging academia, industry, NIH and non-for profit organizations in a joint effort in the clinical development of novel therapeutics for brain disorders.
