Research Focus

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.

Research

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.

Biography

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.
