Dr Samir Agrawal


Barts Health NHS Trust and Barts Cancer Institute, Queen Mary University of London, London, UK

Samir Agrawal is a Senior Lecturer in Haematology at the Queen Mary University of London and a Consultant Haemato-Oncologist at St Bartholomew’s Hospitals and The Barts Health NHS Trust, London UK.

Dr Agrawal qualified at the University of Bristol, UK, trained at The Royal Marsden Cancer Hospital, London, UK, and was awarded his PhD in Tumour Immunology from the University of Paris, France. He is Director of the Stem Cell Laboratory of the Barts Health NHS Trust, and has an interest in diagnostic immunophenotyping. He was a winner of the NHS Innovator Award in 2006 for the introduction of new diagnostic tests for the diagnosis of human leukaemias.

Dr Agrawal’s clinical activities stretch across all areas of haematological cancers, ranging from intensive chemotherapy for acute leukaemia to outpatient non-intensive chemo-immunotherapy for lymphoid diseases, particularly chronic lymphocytic leukaemia (CLL) and other lymphoid malignancies. Dr Agrawal has designed, funded, and implemented studies on myelodysplastic syndromes, invasive aspergillosis and CLL. A former member of the UK CLL Trials Committee, he is a trustee for CLLSA (the patient-led support organisation for patients in the UK with CLL), as well as a NICE reviewer and the haemato-oncology representative on the UK IVIg initiative. He is a member of the European group (ECIL) for guidelines for infection management.

Dr Agrawal’s research activities are focussed on CLL biology and developing novel approaches to treating this incurable disease; and improving patient experience with the development of the “remote patient monitoring programme”, which allows specialist follow-up without requiring attendance at the hospital. His current activities in the field of invasive fungal disease include a diagnostic study of high-risk haematology patients looking at improved and earlier diagnosis. He is also working to develop clinical guidelines and integrated care pathways for managing infection in the high-risk haemato-oncology setting and to promote best practice and highlight new developments through educational meetings.

Dr Agrawal has published over 70 papers in journals such as the Journal of Clinical Investigation, Journal of Immunology, Blood, the British Medical Journal, and the Journal of Clinical Oncology.

Dr Moritz Hundertmark

MD, DPhil Candidate

Clinical Research Fellow, Oxford Centre for Clinical Magnetic Resonance Research, Oxford University, UK

Dr. Hundertmark is a fully licensed doctor in both the UK and Germany.

He is currently a Senior Research Fellow at Oxford University where he is completing the final year of his DPhil (PhD), investigating new pharmaceutical targets for heart failure patients in clinical trials.

He sees NHS patients at the John Radcliffe Hospital, Oxford. Until August 2021 he also held a role in Cardiology and Cardio-Thoracic surgery at The Harley Street Clinic, London (HCA Healthcare UK) where he regularly saw oncology patients for interventional management, such as radiofrequency ablation of cancerous tissues, and pleurodesis for recurrent cancer related pleural effusions.

His research interest lies in the field of energy metabolism and how both pharmacological and lifestyle interventions may augment failing organ systems. He has recently concentrated on novel spectroscopy imaging techniques to further investigate patients with cardio-metabolic diseases and has published on these topics in high-impact journals, such as the European Heart Journal and Circulation.

During the early part of his career, he gained extensive international experience, completing his undergraduate degree, and qualifying as a doctor in Würzburg (Germany), Bern (Switzerland) and Johannesburg (South Africa). He then began to train in general internal medicine and cardiology at University Hospital, Würzburg, and his MD thesis investigated a mutation in a gene causing dilated cardiomyopathy. This was followed by a role in intensive care medicine at the University Clinic Halle (Germany) before relocation to UK to pursue an academic career in Oxford.

He now actively represents aspiring internal medicine physicians as the Chair of the working group for Europe’s biggest medico-scientific society (German Society for Internal Medicine, DGIM).

Dr Hundertmark’s strong clinical background and European experience, combined with a research focus on metabolic systems and pathways, makes him an excellent fit with the medical team at COC.
