My main interests are in the molecular control of cell fate and homeostasis of resident progenitor and stem cells in the developing and adult human brain. Using genomics approaches we have begun to identify an array of signaling pathways which operate in the regulation of human neural progenitors. We are currently assessing the functional significance of these pathways using pharmacolgical and lentiviral based overexpression and shRNAi in vitro, and with in vivo models of CNS demyelination/remyelination.
