Research focus
My lab seeks to understand tumor ecosystems at single-cell resolution during the development and evolution of cancer. We develop analytical approaches for the integration and interpretation of multidimensional genomic data, including single-cell RNA-sequencing, whole genome sequence data, and emerging genomic technologies. A chief area of focus is the study of intratumoral heterogeneity and its relationship to clonal evolution, treatment response, and the tumor microenvironment in glioblastoma.
