Description:	It is well established that memory exists in time-dependent phases and is converted from a labile to a stable state after training by a process termed consolidation. Further, the memory process can be strongly affected by motivational state. Using olfactory memory in the fruit fly Drosophila as a model, and applying state-of-the-art genetic manipulations, Dr. Waddell’s laboratory studies the mechanisms by which memory is encoded and stabilized at the molecular, cellular and neural network level, and by which motivational states can regulate access to memory. Scott Waddell received his B. Sc. from the Department of Biochemistry at the University of Dundee and his Ph.D. from the University of London, U.K. He has received numerous awards and honors including a Wellcome International Prize Traveling Fellowship and a Merck / M.I.T. Fellowship to do postdoctoral work at the Massachusetts Institute of Technology. He joined the Department of Neurobiology at the University of Massachusetts Medical School as a faculty member in October 2001 where he is presently an associate professor.
