Research Interests

Our lab's goal is to identify molecular mechanisms of leukemia stem cell self-renewal in acute myeloid leukemia (AML). Self-renewal is a feature of leukemia stem cells that allow them to recapitulate leukemia and cause relapse. Since AML cells are highly heterogenous, we specialize in the application of single-cell, high throughput technologies (including mass cytometry/CyTOF and single-cell RNA sequencing) to address these research questions. We believe that this approach will identify effective therapeutic targets for this deadly disease.
