Research Focus

My research focuses on understanding the genetic and molecular mechanisms that underlie the initiation and progression of non-Hodgkin's lymphomas in order to define clinically-relevant biomarkers.

Research

We are a translational lymphoma biology lab. Our key research questions are to:

  • Understand the molecular processes that govern lymphoma initiation
  • Characterise intra-tumour heterogeneity and evolution and their role in lymphoma progression
  • Define novel disease- and treatment-associated biomarkers that can be translated to clinical practice

To address these questions, we aim to leverage primary lymphoma samples, including from Phase II and III clinical trials, in combination with cutting-edge multi-omic technologies, in vitro models and computational biology approaches.

Biography

I graduated in medicine from the University of Cambridge and subsequently undertook my medical and specialty haematology training in London. My research interest in lymphoma biology was developed during my Kay Kendall funded Clinical Research Fellowship with Professor Jude Fitzgibbon at the Barts Cancer Institute where I investigated the genetic heterogeneity and tumour evolution underlying follicular lymphoma and its progression. I was awarded the Royal College of Pathologists Specialty Research Medal for this work. In 2017, I was selected as a scholar of the prestigious ASH-EHA Translational Research Training in Haematology (TRTH) program in 2018 and returned to the Barts Cancer Institute as a Cancer Research UK-funded Clinician Scientist to establish my own group. I am also a practising Consultant Haemato-Oncologist at St Bartholomew’s Hospital. I lead several of the translational science programs on UK lymphoma clinical trials.
