Research Focus

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

Research

I have a research interest in B-cell Non-Hodgkin’s lymphoma. Our current focus is on follicular lymphoma, an indolent malignancy that remains incurable and for which the typical clinical course is one where patients relapse on several occasions eventually becoming therapy resistant. Our main 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 biomarkers that can be translated to clinical practice

To address these questions, we aim to utilise primary lymphoma samples in combination with cutting-edge tools, in vitro and in vivo approaches.

Biography

I graduated in medicine from the University of Cambridge and subsequently undertook my medical and specialty registrar haematology training in London. My research interests 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.

I returned to the Barts Cancer Institute as a Clinical Senior Lecturer in 2017 and will also be working with collaborators at the Francis Crick Institute.
