Mr Jonathan De Siqueira


I graduated from the School of Medicine (MBChB) at the University of Leeds in 2009. During my time as an undergraduate, I also undertook an intercalated degree in biomedical ethics (BA – First Class Honours). I then enrolled in full-time clinical postgraduate foundation and core surgical training and attained Membership to the Royal College of Surgeons (MRCS) in 2011. During core surgical training, I undertook Out of Programme Experience, working as a Leadership and Management Fellow within the Yorkshire School of Surgery; where I developed and delivered technical and non-technical simulation training programmes to enhance the skills development of surgical trainees.

Following Core Surgical Training, I joined the Endothelial Cell Biology Unit, at the University of Leeds, where my thesis explored the role of synthetic protein scaffolds in the detection and modulation of Lectin-like Oxidised Low Density Protein Receptor-1 (MD, 2014-2017). On the conclusion of my postgraduate research, I rejoined full-time postgraduate clinical training as a Higher Surgical Trainee in Vascular Surgery. In 2019, I was appointed as NIHR Clinical Lecturer in Vascular Surgery, a role which encompasses a 50% time commitment to research and 50% to clinical training. 

Research interests

My current area of research interest is in vascular access surgery for haemodialysis, particularly in the areas of patient selection, pre-operative work-up and fistula maturation.
