I am an academic vascular surgeon. I am internationally recognised for my contributions to clinical and laboratory studies of abdominal aortic aneurysm (AAA). I have particular expertise in the genomics of AAA having led worldwide collaborations to deliver genome-wide association studies that have identified the majority of the known genomic risk loci for AAA. I have more recently developed a complementary research programme in AAA screening and have both led and contributed to clinical studies of AAA screening that are changing NHS practice.
