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 diseases in combination with genomic and proteomic analyses, advanced imaging, electrophysiology, and functional and behavioural 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 stress- and ischemia- induced cell injury; 3) to develop pharmacological strategies for cytoprotection against the cell injury. We also interest in channelopathy (ion channel diseases).
