Current research news

We are looking for men with abdominal aortic aneurysms (AAA) to join our UK Aneurysm Growth Study research programme. More information can be found on the project page here.



I was initially appointed as a Clinical Lecturer in 2003 and, following the award of my CCT and a HEFCE Clinical Senior Lecturer Fellowship, was appointed as a Senior Lecturer in 2010. In 2016 I was promoted to the position of Professor of Vascular Surgery.

Research Interests

During my time with the department I have been involved in a continuing research programme investigating the pathogenesis and management of abdominal aortic aneurysms (AAA). My laboratory research mainly involves genomic studies of AAA and to date we have identified key novel associations between AAA and the LRP1, LDLR and SORT1 genes. My clinical research is focussed on the management of early-stage aneurysmal disease including screening.

With previous funding from the Circulation Foundation, and now the British Heart Foundation, I have set up the UK Aneurysm Growth Study, a large prospective cohort study of men with small AAA. This resource will be used to identify clinical and biological factors associated with the growth of AAA and bring together my previous laboratory research with my current clinical research.

I provided clinical input for the NIHR HTA project, “RESCAN”. Through the analysis of over 15,000 individual AAA patient datasets we were able to identify that lengthening the intervals between AAA surveillance scans was feasible whilst remaining clinically effective at preventing AAA rupture. These new surveillance intervals are currently under consideration by the NHS AAA Screening Programme and the primary results of this project were published in JAMA (2013).

I am currently working with colleagues from Cambridge, Brunel and Imperial College on an NIHR HTA funded project "Screening Women for Abdominal Aortic Aneurysms (SWAN)" to construct an economic model for AAA screening in women. In 2016 I obtained funding from the NIHR to conduct a pilot study of AAA screening in women, the "Female Aneurysm screening STudy (FAST)". Together these two projects will help the NHS decide whether to screen women for AAAs.
