Research

My laboratory studies the molecular and cellular mechanisms that control the generation and differentiation of glial cells. While glia constitute roughly 90% of the central nervous system (CNS) and are associated with numerous neurological disorders and malignancies, the transcriptional mechanisms that control their development and diversity remain shrouded in mystery. 

Using prospective isolation of stem cell populations from different stages of embryonic spinal cord, coupled with microarray analysis, we have identified a family of transcription factors (the Nuclear Factor I family or NFI) that control the specification of glial cell identity.Using the induction of NFI genes at the onset of gliogenesis as a starting point, my laboratory has begun to unravel the upstream and downstream mechanisms that encompass NFI gene function during this crucial developmental interval. Another focal point of my laboratory is to translate the molecular mechanisms that control glial fate determination to neurological disease. We have found that NFI genes are also expressed in human gliomas and and human white matter injury (HIE and Multiple Sclerosis) and contributes to the associated pathology of these diseases in animal models. Therefore the goal of my research program is identify novel paradigms controlling gliogenesis and determine whether they contribute to neurological disease.
