Research

Our research focuses the dissection of mechanisms that underlie response and resistance to immunotherapies and on the longitudinal tracking of tumor cell evolution using single-cell lineage-tracing approaches based on interrogation of natural barcodes like somatic nuclear or mitochondrial DNA mutations.
