QMUL Directory

My clinical and research interests are allogeneic haematopoietic stem cell transplantation (HSCT); graft-versus-host disease (GvHD)/graft-versus-tumour (GvT) effects; and adoptive immunotherapy.

Research Details

In the lab I focus on the development of novel approaches to improve efficacy and reduce toxicity of allogeneic HSCT and adoptive immunotherapy as treatments for blood cancers and other diseases.

Current funded research projects include pharmacological modulation of immune responses after allogeneic HSCT, genetic manipulation of donor cells to externally control their phenotype and examination of the metabolic pathways that trigger gastro-intestinal GvHD.

I now combine my laboratory and translational research programme with clinical practice with the Cancer Centre at Barts Health, with specific emphasis on the lymphoma service and development of the allogeneic transplant/immunotherapy programmes.


I developed my research interest during my MRC Clinical Research Training Fellowship at the Royal Free Hospital, London, where I studied ways to selectively deplete alloreactive donor T cells to reduce GvHD but maintain immune reconstitution after allogeneic HSCT. I was awarded the George Santos Award by the American Society for Blood and Marrow Transplantation for the best clinical research by a young investigator for this research.

In 2006, I joined the Dana-Farber Cancer Institute/Harvard Medical School as a junior faculty member in Medical Oncology. I performed translational research with Profs Lee Nadler and Eva Guinan using costimulatory blockade to induce allospecific anergy in donor lymphocytes, to reduce GvHD but preserve immune reconstitution and GvL effects after allogeneic HSCT.

During that time I also gained experience in other adoptive immunotherapy approaches to cancer treatment, and I was the recipient of a Career Development Award from the Leukaemia and Lymphoma Society and a New Investigator Award from the American Society for Blood and Marrow Transplantation.

In 2010 I joined the Centre for Haemato-Oncology in the Barts Cancer Institute as a Clinical Senior Lecturer funded initially as a Clinician Scientist by the MRC.
