My research is focused on elucidating the molecular and cellular mechanisms of signal transduction in neurodegenerative diseases and neurological disorders. To that end, we are currently focused on the role of microRNAs as effectors of post-transcriptional regulators of gene expression in response to ischemia and neuroprotection, as well as for signaling pathways mediated by the metabotropic glutamate receptors. We use a variety of molecular and biochemical techniques, including proteomics, microarrays, quantitative PCR, immunocytochemistry, immunoblots, RNA blots, in situ hybridization, RNAi, and enzymatic assays.
