Ralph Greenspan

Professor In Residence, Division of Biological Sciences, UC San Diego

Dr. Ralph J. Greenspan has worked on the genetic basis of behavior and brain function in fruit flies (Drosophila melanogaster) almost since the inception of the field, studying with one of its founders, Jeffery Hall, at Brandeis University in Massachusetts, where he received his Ph.D. in biology in 1979. He is currently Associate Director of the Kavli Institute for Brain and Mind at the University of California San Diego. Dr. Greenspan’s research includes studies of the consequences of mutations and localized genetic alterations in the nervous, molecular identification of genes causing naturally occurring variation in behavior, and the genetic analysis of fruit fly sleep and attention. His current research addresses large-scale network questions pertaining to the action of genes and neurons. In addition to research papers, he has authored: Fly Pushing: The Theory and Practice of Drosophila Genetics, , An Introduction to Nervous Systems, and How Genes Influence Behaviour (with Jonathan Flint and Ken Kendler).
