Research

Leukaemia initiating cells (LIC) are required for initiation and maintenance of leukaemic growth.

Current therapies fail to target these deleterious subsets resulting in a persistent risk of relapse. My group's overarching aim is to gain fundamental insight into the underlying biology of LICs with the aim of revealing dependencies that are tractable targets for therapy.

My previous work established the dominance of “niche” derived factors in driving LIC activity over cell intrinsic oncogenes providing a rationale for niche based therapy. Our ongoing studies aim to evolve our understanding of the role of microenvironment in determining the phenotypes of LIC’s, in particular cellular dormancy, an essential mechanism conferring chemo protection.

Using tractable xenotransplanation models, cellular imaging, high resolution genomics and proteomics, we aim to provide a comprehensive and coherent portrait of the complex biology of ALL- LICs with the overall aim of informing strategies for minimising leukaemia recurrence.

My laboratory interests are complimented by my clinical expertise in adult ALL (Honorary Consultant, Dept of Haemato-Oncology, St Bartholomew’s hospital). I am a member of the National Cancer Research Institute adult ALL subgroup which leads the UK’s clinical trial portfolio.
