I joined ScHARR in 2004 and was appointed as a Research Fellow in 2007. In early 2011 I was appointed Senior Lecturer in Health Technology Assessment (HTA) and was the first Course Director of the MSc in International Health Technology Assessment, Pricing and Reimbursement (iHTA), with responsibility for developing and running the programme. The MSc is now in its eighth year. In 2014 I was promoted to Reader and made a University Senate Fellow for Excellence in Learning and Teaching. I stepped down as Course Director of the iHTA programme in mid-2015 and returned to working for the ScHARR Technology Assessment Group (TAG) conducting appraisals for NICE. I was previously the Lead for the systematic reviewers in HEDS (2017-18), and in 2018 was appointed Deputy Director of Health Economics and Decision Science and the REF co-ordinator for the School.
