Biography:

My research focuses on the mechanism of remyelination of the central nervous system after demyelination in various conditions. Demyelinating injury initialises a repair process, which involves oligodendrocyte progenitor cells (a type of adult stem cells) turning into mature myelinating oligodendrocytes which replace the lost myelin sheath of the axons. Failure of this process can result in axonal loss and permanent functional deficits, as seen in diseases such as multiple sclerosis. Understanding the remyelination process, including the regulatory factors in injury environment and the cell's intrinsic properties is essential for finding means of enhancing the repair of normally non-repairable clinical conditions. We combine molecular and cellular techniques, genetic approaches and in vivo demyelination models to dissect this complicated process focusing on the activation and differentiation of adult stem cells.
