Research

My research is motivated by a translational goal: to understand the cellular architecture of glioblastoma (GBM) well enough to design therapies that target it precisely. Working in the Bhaduri Lab at UCLA, I combine clonal barcoding (CellTagging), single-cell transcriptomics, and in vitro and in vivo models to map progenitor hierarchies in patient-derived GBM and identify the cell populations that drive therapeutic resistance.

A central finding of my PhD is that GBM heterogeneity is not random. It is organized by restricted progenitor populations that give rise to predictable clonal lineages. This structure creates cell type-specific dependencies that can be targeted therapeutically.

A second line of work identified a neurovascular progenitor (NVP) state that sits at the convergence of multiple GBM lineage trajectories. This population expresses a hybrid transcriptional program bridging neural and vascular identities, and appears to play a central role in sustaining tumor plasticity.

Together, this body of work advances a framework of lineage-resolved progenitor organization as a foundation for rational, cell type-specific therapeutic targeting in GBM. My dissertation is titled Lineage-Resolved Progenitor Organization as a Framework for Therapeutic Targeting in Glioblastoma.
