Professor Bijan Modarai is the KCL Chair in Vascular Surgery and a British Heart Foundation (BHF) Senior Clinical Research Fellow. He completed his Basic Surgical Training in London before being awarded a BHF Clinical PhD Studentship in 2002. He graduated with a PhD in Biochemistry in 2006 and completed his Higher Surgical Training as an NIHR Academic Clinical Lecturer at KCL and as an Endovascular Fellow at The Royal Prince Alfred Hospital in Sydney. He was appointed as a Senior Lecturer in Vascular Surgery at KCL and Honorary Consultant Vascular Surgeon at GSTT in 2012, having secured a BHF Intermediate Clinical Research Fellowship. He was awarded a Hunterian Professorship by The Royal College of Surgeons of England in 2017. 

He is a Council member of the British Society for Endovascular Therapy, examines for the Fellowship of European Board of Vascular Surgery and co-leads the GSTT/KCL Biomedical Research Centre School of Translational and Experimental Medicine.

His translational research leverages both basic science and clinical expertise to inform the management of patients with arterial disease.

The main area of research is aimed at developing novel therapeutic and diagnostic strategies for patients with critical limb ischaemia, including arteriogenic cell therapies, the use of biomaterials to enhance cell therapy and novel imaging techniques applied to the limb. This work has led to clinical studies that are currently underway in collaboration with national and international partners. These partners include fellow Principal Investigators in the BHF Centre for Vascular Regeneration. 

Other research focuses on the biological consequences of arterial interventions. Examples include studies on the deleterious effects of low dose radiation exposure during x-ray guided endovascular procedures and also work aimed at elucidating the pathophysiology of spinal cord ischaemia after endovascular aortic repair.
