Biography:
I was trained in Medicine at Cambridge, and took junior hospital posts around England before being appointed Clinical Lecturer in Cardiology at the University of Sheffield in 1994 and BCS Young Investigator of the Year 1995. I was trained in Cardiology in Sheffield, and in coronary angioplasty by Professor David Cumberland. I was appointed Senior Lecturer in 2000 and became Reader in Interventional Cardiology in 2014 and Professor in 2016. I am a member of the Cardiovascular Biomechanics theme, with strong links with the Medical Physics Group, within the Department of Infection, Immunity & Cardiovascular Disease, and the Insigneo Institute for in silico medicine.
Research Activities:
My higher degree was in the field of local coronary artery injury and healing, and my interests since then have exclusively centred on coronary artery disease (CAD), its endovascular treatment with percutaneous coronary intervention (PCI; angioplasty), the injury and healing resulting from that, and how we can improve upon the results of PCI. This research has spanned basic research, in vivo experimentation, translation into clinical studies and clinical decision making. Increasingly I am focusing on the application of computer models of coronary artery disease to develop ‘virtual’ coronary physiology based upon the coronary angiogram. I supervise Academic Clinical Fellows and students at BMedSci, MD and PhD level and welcome applications from students interested in undertaking projects in the field of computational modelling of coronary artery blood flow.
Teaching Interests:
I lecture to undergraduate medical students and enjoy bedside teaching. I also teach Cardiology trainees on a regional level. I am a trainer in PCI in Sheffield and lecture on advanced PCI techniques nationally and internationally. I also teach on the Molecular Medicine MSc course. I have taught 21 BMedSci, 7 MD and 8 PhD students.
Professional Activities:
I am Honorary Consultant Cardiologist at the Sheffield Teaching Hospitals NHS Foundation Trust and Lead for Acute Coronary Syndrome Pathways, Sheffield Teaching Hospitals Foundation Trust. I am Chairman of the Insigneo Cardiovascular Working Group. I am a member of the British Cardiovascular Society, and of the British Cardiovascular Intervention Society and its R&D committee. I am a Supervisor for the Wellcome 4Ward North Clinical PhD Programme, and Member of the EPSRC Image-guided therapies UK Newtork. I am reviewer for six Cardiology journals and for the BHF, MRC and NIHR.
Current Projects:
- Computer modelling of coronary artery disease and blood flow.
- Clinical decision making in coronary artery disease.
- Complex percutaneous coronary interventions.
- Translational clinical trials in these areas.
I currently hold NIHR, BHF and MRC-DPFS grants.
