I have accumulated over 40 years of experience in the fields of transfusion science and clinical transfusion. Qualifying in 1984 as a registered Biomedical Scientist while working for NHS Blood and Transplant, I later took on the management of the Transfusion Laboratory at Oldchurch Hospital before finally moving to North Middlesex University Hospital NHS Trust in the early 1990s. It is here that I became interested in the transfusion needs of patients with inherited red cell disorders. Thanks to the support and encouragement of Dr Anne Yardumian, the Red Cell Consultant Lead, I had the opportunity to become more deeply involved in an expanded patient-facing role, supporting the wider clinical needs of transfusion-dependent patients beyond ensuring the delivery of the right blood to the right patient.
I have a passion for my chosen career, loving transfusion science as much now as when I first started. I have actively encouraged this passion in others, being involved in the training and education of biomedical scientists, nurses and clinicians. At a national level, I have been instrumental in the development of the role of Transfusion Practitioners, sit on a number of specialist advisory boards, and have examined for the Institute of Biomedical Scientists and the Royal College of Pathologists. My work has been recognised internationally with invitations to speak at conferences and through publications.
It has been an honour and a privilege to have had the opportunity to work with patients having inherited red cell disorders. They have taught me so much, both in a professional and a personal capacity, about what is important and what is not so important in living with their disorder and its management. I am delighted to have been invited to be a trustee for the UK Forum for Haemoglobin Disorders and I hope that my background as an allied health professional, along with my passion for improving the quality and accessibility of care for all patients living with a red cell disorder, will bring a different perspective to the discussion and work of the committee.
