Research

Glia are the most abundant cell type in the adult central nervous system (CNS) and support a diverse array of physiological functions including myelination, synaptogenesis, neurotransmission, and blood-brain barrier maintenance. Consistent with this functional heterogeneity, disruptions in normal gliogenesis and glial maintenance have been reported as defining events in the onset and progression of several neurological disorders and malignancies. Despite their essential and emerging roles in CNS functions and pathologies, the molecular mechanisms that govern glial cell specification from neural progenitors and how these mechanisms are correlated with associated diseases are poorly defined. Specification and lineage commitment involves coordinated gene expression regulated by chromatin remodeling, transcriptional cascades, and binding site recognition. Understanding how these regulatory layers converge to influence gene expression remains a key question with implications in neural development, function, and associated disease.

In my laboratory, we use interdisciplinary approaches to study both glial development and ultimately, neurodegenerative diseases and glioma. Specifically, we are interested in dissecting the mechanisms underlying transcriptional regulation and chromatin architecture of glial cell development and applying these developmental concepts to glioma tumorigenesis. Methodologically, we utilize manipulation of both chick and mouse model systems in combination with biochemical and transcriptional assays to help elucidate these molecular underpinnings.
