Gerald D. Fischbach

Chief Scientist, Simons Foundation

Gerald Fischbach joined the Simons Foundation in early 2006 to oversee the Simons Foundation Autism Research Initiative. Formerly, he was dean of the faculty of health sciences and of medicine at Columbia University, and director of the National Institute of Neurological Disorders and Stroke at the National Institutes of Health (NIH) from 1998-2001. Fischbach received his M.D. in 1965 from Cornell University Medical School and interned at the University of Washington Hospital in Seattle. He began his research career at the NIH from 1966-1973. He subsequently served on the faculty of Harvard Medical School, first as associate professor of pharmacology from 1973-1978 and then as professor until 1981. From 1981-1990, Fischbach was the Edison Professor of Neurobiology and head of the anatomy and neurobiology department at Washington University School of Medicine. In 1990, he returned to Harvard Medical School, where he was the Nathan Marsh Pusey Professor of Neurobiology and chairman of the neurobiology departments of Harvard Medical School and Massachusetts General Hospital until 1998. Throughout his career, Fischbach has studied the formation and maintenance of synapses, the junctions between nerve cells and their targets, through which information is transferred in the nervous system. He pioneered the use of nerve cell cultures to study the electrophysiology, morphology, and biochemistry of developing nerve-muscle and inter-neuronal synapses. His current research is focused on the roles that neurotrophic factors play in determination of neural precursor fate, synapse formation and neuronal survival. Fischbach is a past president of the Society for Neuroscience and serves on several medical and scientific advisory boards. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences and the Institute of Medicine, a fellow of the American Association for the Advancement of Science, and a non-resident fellow of the Salk Institute.

Exclusive: Janelia sunsets rodent work, launches transparent fish project

The Howard Hughes Medical Institute’s Janelia Research Campus is banking on whole-brain imaging in the Danionella fish to advance neuroscience, but some scientists forced to close their labs say that even with a three-year runway and transitional support, they feel betrayed by the pivot.
