Research

Myelodysplastic Syndromes (MDS) and Acute myeloid leukaemia (AML) are both clonal diseases that harbour MDS stem cells (MDS-SC) and pre-leukemic cells, respectively. Various studies have demonstrated that acquired mutations in haematopoietic cells' genes can lead to clonal fitness and eventually to propagation of the disease. Understanding the switch between clonal haematopoiesis and clonal disease is one of the major challenges of the scientific community, which highlights the need to unravel how epigenetic/spliceosome stresses are integrated by stem cells and dictate their clonal fate.

In the lab we develop in-vitro and in-vivo modelling of MDS and AML diseases. Using primary human samples and multi-omics approaches including RNAseq (Bulk & single cell), Proteomics, Phosphoproteomics, Metabolomics and drug screening, we challenge normal and malignant haematopoiesis to unveil new therapeutic targets in myeloid malignancies.

Key words: Stem cells, patient samples, AML, MDS, splicing, RNA biology, metabolism and translation regulation.

Biography

Since 2018, I have led a team of 3-4 lab members in the Centre for Haemato-Oncology at the Barts Cancer Institute (QMUL). In September 2021, I was made tenured. I have acquired a national and international reputation as an expert in human haematopoietic stem cell biology, clonal evolution and haematological diseases modelling and have published seminal studies in different journals (including, Cell Stem Cell, Leukaemia, Haematologica, Nature Communications, British Journal of Haematology and Science Translational Medicine). My studies on myelodysplastic syndromes and acute myeloid leukaemia have pioneered important, robust methods for assaying clonal dynamic of hematopoietic stem cell function in health and disease, providing reference tools to the scientific community to screen drugs, to challenge putative target genes and study cross-talk between micro-environment and haematopoietic cells. Using cutting edge technologies on human primary cells we aim to reveal novel mechanisms regulating stem cells’ RNA biology and proteostasis.
