Postdoctoral Associate- Genetics and Circuitry of Sleep

A postdoctoral associate position is available to study the molecular and circuit basis of sleep.  We use sophisticated genetic approaches in Drosophila and mice to study the genes and circuitry underlying sleep, a fundamental and evolutionary conserved behavior.  We are studying the homeostatic and circadian mechanisms regulating sleep, and also have deep interest in understanding the functions of sleep.  To carry out these studies, we combine molecular and genetic approaches with high throughput behavioral assays, immunohistochemical techniques, patch-clamp electrophysiology, and in vivo functional imaging.  Applicants should have a Ph.D. and/or M.D. and be creative and highly motivated.  A strong background in electrophysiology is desirable.  For more information, please visit our website:
