Research Interests: Our research interest is in studying the role of ion channels in neuroprotection against cerebral ischemia and stroke, and identifying potential therapeutic targets for stroke. The experimental approaches used in our lab include in-vivo animal models of human diseases in combination with genomic analyses, advanced imaging, electrophysiology, and functional and behavioral assessments. These approaches will allow us to: 1) study the cellular and molecular mechanisms underlying ischemia and stroke; 2) to identify potential molecular targets that are responsible for the hypoxic- and ischemia- induced cell injury; 3) to develop pharmacological strategies for cytoprotection against the cell injury and potential stroke treatment.

Detailed Description: Our research focuses on understanding neurobiology of stress and diseases, including: 1.) the cellular, molecular and functional mechanisms of cerebral ischemia and hypoxia in different species, and 2.) gene and protein alternations after ischemia and hypoxia in different species which could apply to potential neuroprotection in these animal models - using multidisciplinary approaches in combination with molecular biology, biochemistry, advance imaging (immunocytochemistry/immunohistochemistry, confocal microscopy and Laser Capture microdissection), in vivo animal models of stress and diseases (hypoxia, global / focal ischemia), electrophysiology, behavioral and functional assessments, and bioelectric signal approaches (biomedical engineering / instrumentation).
Cell and tissue culture: Hippocampal cells, neurons.
Procedures: Behavioural tests, electrophysiology, immunohistochemistry, immunocytochemistry, in-vitro electrophysiology, in-vivo electrophysiology, micro and macrostimulation of peripheral nerves and central brain structures, RT-PCR, siRNA, stereotaxic brain surgery, vagotomy, vessel cannulation, western blot.
Dissecting microscope, stimulator.
