Dr. Nussbaum is currently the Holly Smith Professor of Medicine and member of the Institute of Human Genetics at UCSF. At UCSF, he is Chief of the Division of Genomic Medicine, and leads both the Cancer Risk Program at the Helen Diller Family Cancer Center and the UCSF Program in Cardiovascular Genetics. He is a member of the Executive Committee of the UCSF Institute for Human Genetics and directs the recently formed Genomic Medicine Initiative at UCSF. He came to UCSF in 2006 from the Division of Intramural Research of the National Human Genome Research Institute, NIH, where he served for 12 years as Chief of the Genetic Diseases Research and Inherited Disease Research Branches. Before his time at NIH, he was a faculty member in the Department of Genetics at the University of Pennsylvania and an Attending Physician at Children’s Hospital of Philadelphia. He received his training in medicine in the Harvard-MIT Joint Program in Health Technology, his internal medicine training at Barnes Hospital/Washington University, and his Genetics training at Baylor College of Medicine. Dr. Nussbaum directed the original research that led to the discovery of mutations in -synuclein in hereditary Parkinson disease in the mid 1990’s and has been studying its role in Parkinson disease ever since. For his work on Parkinson disease, he was awarded the Klaus Joachim Zülch-Prize for Neurological Research and the Jay Van Andel Award for Outstanding Achievement in Parkinson's Disease Research. He also carried out positional cloning and characterization of the gene mutated in Lowe syndrome that led to accurate biochemical and molecular genetic testing, for which he has been recognized three times with awards from the Lowe Syndrome Association. He is the co-author of over 200 peer-reviewed publications in human genetics and co-author with Drs. Roderick M. McInnes and Huntington F. Willard of the popular textbook of human genetics, Thompson and Thompson's Genetics in Medicine. He has received numerous teaching awards from the University of Pennsylvania, the National Human Genome Research Institute and the University of California, San Francisco. Dr. Nussbaum is a Director and Treasurer of the American Board of Medical Genetics and Genomics and has served on the Board of Directors of the American College of Medical Genetics and Genomics and on the Board of the American Society of Human Genetics, where he also served as President. He was elected to the Institute of Medicine in 2004 and the American Academy of Arts and Sciences in 2015. On August 1, Dr. Nussbaum will become the Chief Medical Officer of Invitae, a genetic information company.
