I trained as an undergraduate at the 小欧视频 of Leeds, and as a postgraduate in the UK, Australia and New Zealand. I was an NHS Consultant Haematologist and Director of the Blood and Marrow Transplantation & Cellular Therapy Programme in Sheffield Teaching Hospitals NHS Foundation Trust, UK, from 2002 until my appointment as Professor of Haematology at the 小欧视频 of Sheffield in February 2025.
Nationally, I have held several key leadership roles in Blood and Marrow Transplantation (BMT) and Haemato-oncology, including Clinical Lead for various NICE Guidelines and Chair of the NHS England Clinical Reference Group for BMT (2016-20). From 2017-20, I was Chair of the Intercollegiate Committee on Haematology (ICH) to the Royal College of Physicians and Royal College of Pathologists. I was President of the British Society of Blood and Marrow Transplantation & Cellular Therapy (BSBMTCT) for 2021-22 and continued within the Board of Trustees as Past President (2023-24). In 2022, I was elected to the Board of Trustees of the British Society for Haematology (BSH).
Internationally, I have a long association with the European Society for Blood and Marrow Transplantation (EBMT) and the international accreditation organisation for transplant programmes, 鈥楯ACIE鈥, including JACIE Medical Director (2012-16) and Chair of the JACIE Committee (2015-20). I have served as a member of the EBMT Board and Scientific Council, initially as Autoimmune Diseases Working Party Chair (2016-20) and as Secretary to EBMT from 2020-24.
Academically, I have contributed to the fields of BMT, haematology-oncology and autoimmunity with authorship of over 400 publications (Google Scholar h-index 77, with over 21,000 citations), along with clinical trials, grant awards, educational meetings, teaching, supervision, examination, journal editorship and scientific peer review.
