Scientific Involvement:
2004-           Member, American Society of Hematology

2007-           Member, International Bone and Mineral Society
2008-           Member, ISEH-Society for Hematology and Stem Cells

Research Interests:
My research focuses on two major areas: understanding the role of cell cycle control in fate
decisions in the haemopoietic system and in generating models of human cancer. We use
haemopoiesis as the model system to understand the role of cell cycle regulation in cell fate
decisions, with a particular focus on the partitioning of self-renewal and differentiation fates of
haemopoietic stem cells and to understand the coupling of terminal cell cycle exit with
differentiation of erythroid and myeloid cells. We are also interested in generating faithful
models of human cancer, with our current efforts focused around models of osteosarcoma, the
most common tumour of bone.
