  1. My main research interests are in the etiology, pathology and novel treatments of common neurodegenerative diseases and brain damage. Human samples as well as different experimental and transgenic animal models, including rodents and Drosophila, are employed. A variety of experimental techniques such as manipulation of gene expression via viral infection, in vitro and in vivo electrophysiology, behavioral analysis and in vivo brain imaging are used. Current main projects include:
  2. (i) Role of brain iron dysregulation, and other pathological mechanisms, in the etiology of neurodegenerative diseases especially Alzheimer's disease and Parkinson's disease; (ii) Search for novel treatment strategies for neurodegenerative diseases.
  3. (iii) Mechanisms of hypoxic/ischemia preconditioning in the protection of ischemic brain, especially the critical role of neuron-glia interaction; (iv) Factors contributing to functional recovery after ischemic injury.
