Joseph Takahashi, Ph.D., is Chair of the Department of Neuroscience and an Investigator of the Howard Hughes Medical Institute at UT Southwestern. He currently holds the Loyd B. Sands Distinguished Chair in Neuroscience. Dr. Takahashi received a BA in biology from Swarthmore College in 1974 and a Ph.D. in neuroscience from the University of Oregon, Eugene, in 1981. For postdoctoral training, he was a pharmacology research associate at the National Institute of Mental Health from 1981–1983.
Dr. Takahashi has pioneered the use of forward genetics and positional cloning in the mouse as a tool for discovery of genes underlying neurobiology and behavior, and his discovery of the mouse and human clock genes led to a description of a conserved circadian clock mechanism in animals.
