We focus on understanding the pathogenetic mechanisms underlying leukemogenesis with a special focus on infant leukemia. In particular we are interested in unravelling the biological mechanisms that drive clonal evolution, the emergence of drug resistance, and the role of tumor heterogeneity in these processes, ultimately leading to new effective therapies. We use a combination of state-of-the-art genomic methods, including whole genome, RNA and Exome sequencing as well as single-cell DNA and RNA-sequencing and leukemia mouse models in our work.

We are currently working on the following aims

  1. To identify the complement of genetic and epigenetic changes in KMT2A-R leukemia from infancy to adulthood and determine how they contribute to cellular transformation
  2. To determine the clinical impact of tumor heterogeneity at single-cell resolution
  3. To uncover clonal evolution in serial samples during treatment
  4. To study how therapy impact clonal evolution in leukemia mouse models
