  • Biography icon plus

    Emma Drasar is a Consultant Haematologist working between UCLH and the Whittington NHS trust. She trained at St Barts and the Royal London School of Medicine, University of London and qualified in 2001 and was awarded MRCP in 2006. She completed her Haematology training at King's College Hospital being awarded FRCPath in 2015. She is a member of the British Society of Haematology and the UK Haemoglobinopathy Forum.

    Dr Drasar was appointed Clinical Lecturer in Sickle Cell Disease at King’s from 2009 to 2013. During this time she was awarded a PhD based on research into markers of severity and predictors of organ dysfunction in sickle cell disease and in 2013 was awarded the Early Stage Investigator prize from the British Society of Haematology. She is a Principle Investigator for the BELIEVE trial using luspatacept to improve anaemia in thalassaemia and a Sub-Investigator on a La Jolla trial looking at alternative approaches to iron chelation. She has published 20 papers in peer reviewed scientific journals and is currently an honorary Senior Lecturer at University College London.

    Dr Drasar is the Thalassaemia lead for the UK Peer Review process, assessing specialist centres for their compliance with the UK standards of care for haemoglobinopathy patients and is also the the Network Lead for the North Central London Red cell Network. During her time as network lead Dr Drasar has led on a number of initiatives to improve patient care. This includes holding joint educational days with the North Middlesex and East Anglia Network, standardising of clinical guidelines across the network, standardising the referral process for acutely unwell patients and setting up a weekly network MDT for elective queries. Both Whittington Health and UCLH were successful in fully achieving the requested standards for the NHSE Network CQUIN and have achieved specialist haemoglobinopathy team status. She has also led on establishing an automated apheresis service at the Whittington (including 24 hour emergency cover) via NHSBT and a transient elastography service to monitor patients with liver complications.

    She is passionate about teaching and improving trainee’s knowledge of managing red cell and iron disorders, helping to initiate a British Society of Haematology sponsored course in haematology for Core Medical Trainees. With Dr Noemi Roy (Oxford) she has also created the “Red Cell Roadshow” for Haematology trainees providing an introduction to haemoglobinopathies, targeted at low prevalence areas, which has been extremely successful. She also is a regular speaker at UK Thalassaemia Society and “Red Cells R Us” patients support meetings.
