Greenspan, Ralph - University of California, San Diego

个人简介

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 Director of the Center for Brain Activity Mapping of the Kavli Institute for Brain and Mind at the University of California San Diego, and Professor in the Division of BIology’s Neurobiology Section and the Dept. of Cognitive Science.

研究领域

Dr. Greenspan’s research includes studies of the consequences of mutations and localized genetic alterations in the nervous system, molecular identification of genes underlying naturally occurring variation in behavior, and the genetic analysis of sleep and attention in the fruit fly. His current research addresses large-scale network interactions pertaining to the action of genes and neurons. In 2011, he was one of the small team of scientists that produced the white paper for the White House Office of Science and Technology Policy that eventuated in the BRAIN Initiative, and in 2014 spearheaded the effort to establish the state-funded Cal-BRAIN program and serves as its co-Director. 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).
