Joseph S. Takahashi, Ph.D. is the Loyd B. Sands Distinguished Chair in Neuroscience, an Investigator of the Howard Hughes Medical Institute, and Chair of the Department of Neuroscience at the University of Texas Southwestern Medical Center in Dallas. His research interests are the molecular mechanism of circadian clocks, neuroscience, and the genetic basis of behavior. Dr. Takahashi pioneered the use of genetics in the mouse as a tool for discovery of genes underlying neurobiology and behavior. His awards include the Honma International Prize in Biological Rhythms Research in 1986, W. Alden Spencer Award in Neuroscience from Columbia University in 2001, Eduard Buchner Prize from German Society for Biochemistry and Molecular Biology in 2003 and Outstanding Scientific Achievement Award from the Sleep Research Society in 2012. He was elected a Fellow of the American Academy of Arts and Sciences in 2000, and a Member of the National Academy of Sciences in 2003. He was a co-founder of Hypnion, Inc., a biotech discovery company in Worcester, Mass., that investigated sleep/wake neurobiology and pharmaceuticals (now owned by Eli Lilly and Co.), and is a co-founder of ReSet Therapeutics, Inc., a biotech company that works on the role of clocks in metabolism.
