He was the editor-in-chief of the 2018 Topol Review of NHS Technology and its impact on the workforce. Tarassenko was the driving force behind the creation of the Institute of Biomedical Engineering (IBME) at the University of Oxford, which he directed from its opening in April, 2008 to October, 2012. He established an £8m Centre of Excellence in Medical Engineering within the IBME, and led the Technology & Digital Health theme in the National Institute for Health and Care Research (NIHR) Oxford Biomedical Research Centre from its inception in 2007 until 2022. Under his leadership, the IBME grew from 110 to 220 academic researchers and it was awarded a Queen’s Anniversary Prize for Higher Education in 2015 for “new collaborations between engineering and medicine delivering benefit to patients”. Education Tarassenko completed his BA in Engineering Science in 1978 at Keble College, University of Oxford. Later he obtained his DPhil in 1985, also at the University of Oxford for his work on the early identification of brain haemorrhages in pre-term infants.
