Biographical Sketch 
Jacques Wadiche graduated with a B.A. in Neurobiology and Physiology from Northwestern University where he gained an appreciation for basic science research. From there he worked on nicotinic acetylcholine receptors at Baylor College of Medicine before enrolling in graduate school at the Vollum Institute at Oregon Health Sciences University in Portland, Oregon. His thesis work revealed how glutamate transporters can function as both carriers and ligand-gated ion channels. During his postdoctoral fellowship in Craig Jahr’s laboratory at the Vollum Institute, he studied a phenomenon where the release of several vesicles occur with each action potential at individual synapses. This results in a very high glutamate concentration in the synapse that can saturate postsynaptic receptors and ensure excitation of the postsynaptic neuron. His postdoctoral work also demonstrated how altering the strength of neuronal uptake can determine the extent of extrasynaptic receptor activation. He joined the faculty at UAB as an Assistant Professor in 2006. His laboratory continues to study mechanisms that regulate vesicular release and neuro-glial signaling.



Research/Clinical Interest
Title
Cellular and molecular basis of synaptic transmission and neuronal organization of microcircuits
Description
Our research focuses on the details of synaptic transmission and synaptic plasticity. Experiments in the lab incorporate a multidisciplinary approach of electrophysiological, imaging methods, and molecular biological approaches to study the activity of synapses and glutamate transporters. One model system that we use to study synaptic transmission and glutamate uptake are slices from cerebellum.
