Research Description
I am interested in the signaling pathways regulating proliferation and differentiation in neural stem/progenitor cells and brain tumor cells. My long-term goals are to reveal how the normal proliferation and differentiation of stem cells is controlled in the brain, dissect how perturbations of these pathways results in neurological diseases, and leverage these findings to treat human disease. In my independent lab, I lead a group which includes a senior neurosurgery resident, practicing neuropathologist, and two graduate students. I work collaboratively with neurosurgeons, neurologists, developmental biologists, and cancer systems biology faculty to map cell-to-cell differences in proliferative signaling in neural stem cells, neurodevelopmental disorders, and all grades of brain tumors.

My laboratory uses cytometric approaches to 1) identify proliferative pathways that are differentially active within cell subsets in the stem cell niche of the ventricular-subventricular zone), 2) determine how this pattern of activation is altered in disease states, particularly pediatric neurological disorders and adult high-grade brain tumors, and 3) directly identify subpopulations of progenitor-like brain tumor cells using multiparameter single-cell protein analyses.

Research Keywords
We study the biology of brain tumors and the properties of stem cells in normal brain.
