The McDonnell Center for Cellular and Molecular Neurobiology is offering its fourth annual Postdoctoral Fellowship Program to support outstanding postdoctoral investigators within the Washington University neuroscience community. Applications are welcomed from postdoctoral fellows whose research fits within the Center's overall mission, which is to improve our understanding of the basic mechanisms underlying nervous system function in health and disease. Many specific areas of investigation are within this scope including but not limited to brain development, neural stem cell biology, axon and dendrite biology, synapse function, receptor biology, membrane channels, transporters, growth factors, signaling mechanisms, control of gene expression, mechanisms of intellectual disability, autism spectrum disorders and other neuropsychiatric disorders, brain tumors, and neurodegenerative diseases. Applications must originate from postdoctoral investigators with at least one year of postdoctoral training in a laboratory at Washington University at the time of application. There are no requirements of citizenship or permanent residency status. Staff scientists, senior scientists, and instructors are not eligible to apply. If a postdoctoral fellow receives an award during the final year of postdoctoral training, funds can only be used during the postdoctoral period of training.
