Professional Summary

Research in my laboratory is focused around understanding the epigenetic landscape and regulation of transcriptomic programs critical for quiescence, self-renewal and multi-lineage differentiation, and malignant transformation of hematopoietic stem cells and progenitors (HSC/Ps). In addition, we model hematopoietic disorder using patient derived and gene-edited isogenic iPSCs, and hematopoietic cells regeneration from directed differentiation of healthy donor iPSCs.
Our research in the area of normal HSC/P biology,  leukemic stem cells (LSCs), hematopoietic cell regeneration and disease modeling using iPSCs  have been published in peer reviewed journals including Journal of clinical investigation, Blood, Nature communications, Cell reports, Stem cells translational medicine and Leukemia.
