Research Summary

Gliomas, the most common primary brain tumors, are universally fatal once they progress from low- into high-grade neoplasms. Although as neuropathologists we are pretty good at diagnosing gliomas histologically, our understanding of the molecular pathogenesis of both glioma formation and its malignant transformation is still rudimentary. While gliomas might not be identical in origin and composition, they commonly share abnormalities in signaling pathways that normally control proliferation and differentiation of glial progenitors.

My main research interest is to understand the cellular and molecular mechanisms responsible for the neoplastic transformation of normal human neural progenitors into primary brain tumors and the progression of low-grade to high-grade gliomas. I am applying my research experience in stem cell biology, which I obtained during my post-graduate training with Dr. Fiona Doetsch, and my PhD-expertise in epigenetics, towards understanding better the molecular pathogenesis of human brain tumors. In particular, the lab is interested in uncovering the role for epigenetic mechanisms of regulation in normal and neoplastic glial populations in humans via: DNA methylation, histone modifications, methyl binding protein enrichment, and microRNA regulation. Ongoing research projects include 1) endogenous purification of human neural progenitor cells by FACS and functional characterization of their properties in vitro; 2) analysis of the DNA methylation and chromatin remodeling status of human progenitor cell populations and low- and high-grade human gliomas, focusing on the promoter regions of specific genes; and 3) study of the global reorganization of the transcriptome and methylome during gliomagenesis. Students with interests in these or similar projects are encouraged to contact me.

Additional clinical interests of mine, in collaboration with other faculty on campus, include the role of neuroinflammation in normal and neoplastic CNS as well as the pathogenesis of clonality in autoimmune neurological disorders, such as polymyositis.
