Biographical Sketch
Dr. Song’s research interests focus on studying cellular/molecular mechanisms of microglia in ischemic stroke and traumatic brain injury and tissue repair. Using the advanced Cre-loxP conditional knockout technique and the state-of-the-art RNAseq bioinformatic analysis, she discovers that microglia play critical roles in neuroinflammation, phagocytosis, and microglia-oligodendrocyte crosstalk for white matter remyelination after brain injuries. Dr. Song is investigating ion transporter protein Na/H exchanger in regulating microglial metabolisms in brain tissue repair as a novel therapeutic strategy.
