My major research interest is understanding the metabolism of chronic lymphocytic leukaemia and lymphoma with the aim that this will underpin the development of the next generation of anti-metabolic drugs for these diseases.

My research focus is investigating the interplay between BCR-signalling and metabolism in chronic lymphocytic leukaemia using a variety of proteomic and metabolomic techniques. We are particularly interested in the impact of deletions/mutations of p53 on the metabolism of CLL cells and how this relates to Richter syndrome and other high grade lymphomas.
I combine my laboratory and translational research programme with clinical practice with the Cancer Centre at Barts Health, with specific emphasis on the treatment of lymphoid malignancies including CLL and lymphoma. I have a particular interest in the role of targeted therapies, immunotherapy and bone marrow transplantation in the treatment of these diseases.

I qualified from Oxford University Medical School in 2003 and trained in haematology on the Imperial College training rotation based at Hammersmith hospital.
I developed my research interest during my CRUK Clinical Research Fellowship with Professor Gribben at Barts Cancer Institute where I studied the defects underlying impaired T-cell immunity in chronic lymphocytic leukaemia (CLL) focusing on the impact of lenalidomide, being awarded a PhD in 2013. I stayed in this laboratory for a period of post-doctoral work investigating the expression and function of integrins on CLL cells. I was awarded the Hamblin prize by the UK CLL forum in 2015 for my work documenting the particular differences associated with the presence of trisomy 12.
In 2016, I joined the Centre for Haemato-Oncology in the Barts Cancer Institute as a Clinical Senior Lecturer funded initially as an Intermediate Clinical Fellow by the Wellcome Trust. I have been working at the Francis Crick Institute to investigate the interaction between signalling and metabolism in CLL and lymphoma cells in collaboration with Professor Karen Vousden.
