Research Description
The primary focus of research in our laboratory is to develop a detailed understanding of the cellular and molecular mechanisms by which transient activation of neurotransmitter receptors can induce long-lasting changes in neuronal excitability and synaptic transmission. Such lasting changes in neuronal function are likely to play an important role in a number of normal physiological processes, ranging from acute regulation of animal behavior to more lasting processes such as formation of long-term memory. In addition, these persistent changes are critical for development of a variety of chronic pathological conditions including, Parkinson's disease, schizophrenia epilepsy, drug dependence and other neurological and psychiatric disorders. Generally, neurotransmitters bring about such lasting changes in properties of cells by stimulating formation of intracellular second messengers and activating protein kinases that then alter the properties of key intracellular regulatory proteins. Thus, we have focused our efforts on the roles of G-protein-coupled receptors (GPCRs) and related second messenger/protein kinase systems in regulating neuronal function. We apply a highly multidisciplinary approach to answer these questions and employ a combination of biochemical, imaging, immunological, and molecular biological techniques to study neuromodulation. In all of our studies, our ultimate goal is to understand the impact of cellular and molecular changes to changes in intact neuronal networks and animal behavior that ultimately impact CNS disorders. Thus, we also employ a range of techniques in behavioral and systems neuroscience By developing this range of understanding, we hope to develop novel strategies for treatment of neurological and psychiatric disorders. We are especially interested in schizophrenia and Parkinson's disease.
While our interests in neuromodulation and G protein-mediated signaling are broad, in recent years we have focused primary attention on the physiological roles of a recently discovered family of G protein-coupled glutamate receptors termed metabotropic glutamate receptors (mGluRs). At a circuit level, we have placed a major emphasis on the roles of mGluRs in regulating transmission through the hippocampal formation and in through basal ganglia circuits involved in regulation of motor function and processing of information flow to the cortex. In addition to understanding the roles of mGluRs and other GPCRs in regulating transmission through these circuits, we are placing a significant effort on understanding the precise molecular mechanisms by which GPCRs and signaling cascades activated by these receptors modulate cell excitability and synaptic transmission. These studies are largely focused on identifying protein kinases and phosphatases involved in specific effects, substrates and phosphorylation sites involved, and the impact of such posttranslational changes on protein function. Finally, we are making rapid progress understanding the impact of these changes at a behavioral level. These studies are having a major impact on our understanding of the cellular and systems level mechanisms involved in regulation of complex aspects of animal behavior and disorders of the central nervous system.

Available Postdoctoral Position Details
Posted: 9/18/2009
Postdoctoral position in cellular/molecular neurobiology is available at Vanderbilt University Medical Center. The successful candidate will join a research group that employs a highly multidisciplinary approach to explore the cellular and molecular mechanisms involved in neuromodulation and regulation of animal behavior. The laboratory uses a combination of biochemical, molecular biological, imaging, electrophysiological and behavioral techniques to study regulation of neuronal function by metabotropic glutamate receptors and other G-protein-linked receptors. Also, we have a strong interest in relating cellular and molecular changes to disorders of the central nervous system, including Parkinson|s disease and Schizophrenia.

Research Faculty positions also available for outstanding candidates.
